    Micron offers 2X GDDR5 Speed in 2016




    The next generation
    Micron has promised to launch a new kind of memory that is twice the speed of mainstreams GDDR5 . This will be released during 2016 and will be company's answer to HBM.

    With speeds of 10 to 14 Gb/s the memory will outpace the existing 7.0 Gb/s of 4Gb GDDR5 memory chips from Micron. Even the new larger GDDR5 chips with 8Gb density will end up at 8.0 Gb/s data rate. The information has been confirmed by Kristopher Kido who is Director of Micron’s global Graphics Memory Business.
    With speeds from 10 to 14 Gb the next generation memory will be much faster and provide much needed bandwidth. Micron can easily call this memory GDDR6 as we have heard people from the graphics industry already using the term.
    The new memory will continue to use traditional component form factor, similar to GDDR5, reducing the burden and complexity of design and manufacturing.
    Many might ask why don’t Nvidia and AMD go after HBM 2.0 as this new memory standard offers great speeds and incredible bandwidth. But HMB 2.0 requires interposers that complicate the design of the GPU. The HBM 1.0 still suffers from severe shortages but we hear that things are getting better.
    It looks like that with 14 and 16nm GPUs the 2016 will definitely be a revolutionary year after more than four years being stuck with 28nm designs. Pascal GPU will have 17 billion transistors which is a high number. Combined with the faster memory standards including HBM 2.0 or GDDR6 we are off for some nice treats next year.
    A single GPU 4K resolution with maxiumum details might become reality soon.

    É bom ver que existem avanços ainda neste padrão e como já o tinha referido ontem, dificilmente veremos HBM a chegar ao mercado abaixo dos 250€ nos proximos anos, por isso é normal ver este tipo de avanços.
    Espero que os preços se mantenham no mesmo patamar, mas com a performance a aumnetar devido ás exigencias das altas resoluções que agora começam a ser usadas.

    GDDR6 Memory Being Developed by Micron, Coming to Mid-End Graphic Cards in 2016 – Alleges Report

    The next generation of graphic cards will be getting a big boost in raw processing power thanks to the jump to FinFET technology. However, as any enthusiast knows, memory and bandwidth can quickly become a very undesirable bottleneck. To solve this problem, AMD and JEDEC introduced HBM 1.0 to the market this year and the much more flexible HBM 2.0 standard is expected to debut next year in flagship products. But what about the middle end lineup? The answer to that (according to an exclusive report by Fudzilla), is an upcoming GDDR6 standard.
    A die shot and external analysis of the Fiji die by Chipworks. @ChipWorks.
    GDDR6 memory allegedly landing in 2016, developed by Micron

    Now here is the thing, reports of the upcoming GDDR6 standard have been present as far back as 2012 (example from VR Zone here). There are also a few oddities in what Fudzilla is reporting, which I would like to point out here for clarity’s sake. Firstly, the source is attributing the GDDR6 standard to Micron, while in actuality GDDR is a JEDEC standard and no such verification for GDDR6 currently exists. This new initiative also seems slightly confusing, because Micron is already working on a JEDEC approved GDDR5X standard which will offer around 2x the bandwidth of GDDR5.
    GDDR5X is based on the GDDR5 standard and primarily doubles the prefetch of the standard while preserving “most of the command protocols of GDDR5”. What that means is that while the bandwidth has been doubled, it is not, strictly speaking an improvement of the GDDR5 standard, rather a new branch of the same and arguably a completely new technology (contrary to what the ‘GDDR’X name might suggest). One of the examples given is DDR3 to DDR4, which also happens to be a good approximate analogy to think of the GDDR5 to GDDR5X jump. Unfortunately, we do not, at this point know what difference, if any, there is between GDDR6 and GDDR5X.
    Advertisements


    The source cited “internal sources” for the exclusive report, so it is possible that GDDR6 is actually GDDR5X rebranded (since the come from the same company). It is also possible (not probable!) that Micron is working on two different standard, in collaboration with JEDEC, namely GDDR5X and GDDR6 but that seems unlikely to me. At any rate, GDDR5 has evolved from its 60nm debut in 2007 to a much more sleek and efficient 20nm version in 2015. I wouldn’t be surprised if JEDEC finally decided to define the GDDR6 standard at the 20nm process in 2016. This transition to a lower node allows much higher clocks and low operating voltages – something that was not possible in the early days of the standard.
    In any case, the use of GDDR5X or GDDR6 remains a question in probability. The simple fact of matter is that most middle order graphic cards do not need more bandwidth than what the modern form of GDDR5 can already provide. And since all concerned parties have already achieved economies of scale with GDDR5 there would be very little reason to shift to a brand new standard such as GDDR5X/GDDR6 since HBM 2.0 will more than cater for the high end stuff, where bandwidth can quickly become an actual issue.
    That said, high bandwidth memory in economical packaging (as low as 2GB HBM) will also be arriving by 2016. Companies like SK Hynix have been getting over their initial learning curve and yields are getting more mature by the month. Soon enough, we will be able to get the low end HBM (memory) in mobile devices such as laptops where the energy efficiency of the standard will be able to do wonders. So even in the middle order, the decision of companies shifting to GDDR5X/GDDR6 remains a dubious proposition at best.

    Micron reportedly developing GDDR6 memory

    While HBM still seems set to be the next big thing when it comes to VRAM on high-end graphics cards, we may have another contender in 2016 as reports are claiming that Micron is currently developing GDDR6 memory. This isn’t the first time we have heard about a new version of GDDR memory as some of next year’s Pascal GPUs from Nvidia are rumoured to use GDDR5X memory.
    This information comes from an exclusive Fudzilla report, with the site claiming to be in touch with a source at Micron. The source confirmed that the new GDDR6 memory standard will offer bandwidths as high as 10 to 14 gigabits per 4GB module, in comparison GDDR5 offers 7Gbps per 4GB module.

    One of the benefits of GDDR6 memory will be its similarity to GDDR5, which will make it easy to manufacture and implement with new graphics cards. That said, the new memory may not be able to match the efficiency gains of HBM, on top of that, HBM 2 is also due out next year, which is set to increase performance and efficiency even further.
    Previous rumours have said that the new high-end GPUs from Nvidia and AMD will feature HBM 2, while lower tier cards will now make use of GDDR5X/GDDR6 memory. If this report is to be believed, then this seems like a likely outcome for next year’s new GPU launches.

    Boas!
    Será mais uma guerra de preços entre os fabricantes do que propriamente para nós...

    Micron comments on recent GDDR6 reports

    Earlier this week, reports began circulating surrounding the existence of GDDR6 memory for future graphics cards. The news originated from news site, Fudzilla, which claimed to be in contact with sources familiar with the matter but it seems that right now, Micron is looking to squash any talk about GDDR6 and make its plans for 2016 perfectly clear.
    While the original report claimed that we would see GDDR6 in 2016, Micron has sent out a statement to various press outlets (including KitGuru) to clarify that it will only be launching GDDR5X next year, which is currently tipped to be used on future Nvidia Pascal graphics cards and some of AMD’s future GPUs as well, in addition to HBM 2.

    “The new memory advancements coming from Micron in 2016 are going to be called GDDR5X, not GDDR6. GDDR5X and GDDR6 are not the same product and Micron has not announced any plans involving GDDR6.”
    The memory maker also went on to say that while GDDR5X is coming, it is not intended to be a competitor to HBM: “GDDR5X is intended to provide significant performance improvements to designs that are currently using GDDR5, therefore giving system designers the option of delivering enhanced performance without dramatically altering current architectures”.
    That last part makes a lot of sense, particularly since we have been hearing rumours that HBM 2 will be reserved for future high-end graphics cards, like the next Fury or Titan, while GDDR5X will be used to provide a boost on lower-tier cards, that would have been designed for GDDR5 anyway.

    JEDEC Announces Publication of GDDR5X Graphics Memory Standard

    JEDEC announced the publication of JESD232 Graphics Double Data Rate (GDDR5X) SGRAM. Available for free download from the JEDEC website, the new memory standard is designed to satisfy the increasing need for more memory bandwidth in graphics, gaming, compute, and networking applications.
    GDDR5X is your standard GDDR5 memory however, opposed to delivering 32 byte/access to the memory cells, this is doubled up towards 64 byte/access. And that in theory could double up graphics card memory bandwith. Early indications according to the presentation show numbers with the memory capable of doing up-to 10 to 12 Gbps, and in the future 16 Gbps. So your high-end graphics cardsthese days hover at say 400 GB/s. With GDDR5X that could increase to 800~1000 GB/sec and thus these are very significant improvements, actually they are competitive enough with HBM.
    Jedec:
    Derived from the widely adopted GDDR5 SGRAM JEDEC standard, GDDR5X specifies key elements related to the design and operability of memory chips for applications requiring very high memory bandwidth. With the intent to address the needs of high-performance applications demanding ever higher data rates, GDDR5X is targeting data rates of 10 to 14 Gb/s, a 2X increase over GDDR5. In order to allow a smooth transition from GDDR5, GDDR5X utilizes the same, proven pseudo open drain (POD) signaling as GDDR5.
    “GDDR5X represents a significant leap forward for high end GPU design,” said Mian Quddus, JEDEC Board of Directors Chairman. “Its performance improvements over the prior standard will help enable the next generation of graphics and other high-performance applications.”

    About JEDEC
    JEDEC is the global leader in the development of standards for the microelectronics industry. Thousands of volunteers representing nearly 300 member companies work together in 50 JEDEC committees to meet the needs of every segment of the industry, manufacturers and consumers alike. The publications and standards generated by JEDEC committees are accepted throughout the world. All JEDEC standards are available for free download from the JEDEC website.

    Micron reports early successes in GDDR5X production

    Micron Technology posted an early report on its production of GDDR5X chips today, and the results sound good. The company says it's gotten working silicon back from its fabs earlier than expected, and those parts are already hitting 13Gb/s speeds. That's already toward the top end of the expected speeds for GDDR5X, whose specified transfer rates range from 10 to 14 Gb/s. Micron says those results are "incredibly promising."
    The first Micron GDDR5X chips are being produced on the company's 20-nm process, and they'll be 8Gb (1GB) dies. The company expects mass production of these parts to begin in the summer of this year, and it'll announce sampling dates for the chips later this spring. Tantalizingly, Micron says that going off its early performance results, we could see GDDR5X chips exceed the 14 Gb/s speed range as time goes on. JEDEC standardized GDDR5X graphics memory just a couple weeks ago, so it's heartening to see production of this improved graphics RAM move so fast.

    Micron To Commence Mass Production of GDDR5X Memory in Summer – Early Samples Achieve 13 GB/s Data Rates

    Micron has officially released an update on the status of their GDDR5X memory solution. Last month, JEDEC published the specifications for the upcoming GDDR5X memory which will double the rate of data flow over the existing GDDR5 memory at around the same power envelope. Being a cheaper solution compared to the HBM (High-Bandwidth Memory) design, we might be looking at several next generation graphics cards that make use of the updated memory standard.

    Micron Commences GDDR5X Mass Production in Summer 2016 – Early Samples With 13 GB/s Data Rates

    Micron has officially stated that GDDR5X memory will be going under mass production in summer, this year. This suggests that the yields of the new DRAM will be high and early samples are already achieving speeds of 13 GB/s compared to the 14 GB/s or higher that it is expected to hit when the memory launches.
    Micron is currently ramping GDDR5X to mass production, and will be announcing sample dates later this spring. We plan to be in full volume production this summer. I also hope to give you an update later this year on performance specifications. via Micron
    Feature Benefit
    • QDR mode • Highest data rate in the industry – >13Gbps achieved to date
    • VDD/VDDQ 1.35V • Improved power per bit
    • 190-ball FBGA Package, 0.65mm pitch • Smaller outline – improved electrical performance
    For those who like to know what difference is between GDDR5 and GDDR5X, we know from the official specifications published by JEDEC the both memory standards are not a whole lot different from each other but they aren’t the same thing either. The GDDR5X solution is built upon the DNA of GDDR5 and has been updated to deliver twice the data rate. There are a lot of design changes that went in developing GDDR5X to achieve the faster transfer speeds, higher bandwidth and in a package that consumers just around the same power or even lower. Micron states that GDDR5X uses around 70% of the energy that is consumed by GDDR5.

    The GDDR5X memory supports a 64-bit wide memory access that has double the prefetch against GDDR5 which supports a 32-bit wide memory access. This allows the memory to offer double the bandwidth and at speeds of 1.75 GHz, the GDDR5X memory will achieve data rates of 14 GB/s that will offer bandwidth of 448 GB/s across a 256-bit memory interface. Currently, the fastest GDDR5 solutions like the GTX 980 Ti can achieve a theoretical bandwidth of 336 GB/s while having access to a large 384-bit bus interface clocked at speeds of 1.75 GHz.
    Micron’s GDDR5X program is in full swing and first components have already completed manufacturing. We plan to hit mass production this summer. The team at our Graphics DRAM Design Center in Munich, Germany is doing a fantastic job, too. Not only do we have functional devices earlier than expected, these early components are performing at data rates of more than 13Gb/s! Memory components mature as they move through the development and manufacturing process, so to see first silicon performing at nearly full performance specs was a pleasant surprise—these early results are incredibly promising. Our first generation GDDR5X is an 8Gb (1GB) density manufactured on our 20-nanometer process technology. via Micron
    Compared to GDDR5 which can push speeds of up to 8 GB/s data rate per DRAM, the GDDR5X has speeds of up to 14 GB/s. Currently, Micron has achieved their first breakthrough of 13 GB/s on the 20nm process technology which was used to design a 8 Gb (1 GB) density package. Micron officials however believe that due to such good speeds delivered on early samples, their GDDR5X solution has the potential to achieve speeds even beyond 14 GB/s which is currently the maximum data rate suggested by them.
    Based on the results so far, we believe that GDDR5X has the clear potential to achieve speeds of 14Gbps and potentially beyond. via Micron

    Will Discrete Graphics Cards From NVIDIA/AMD Utilize GDDR5X?

    Now the main question which everyone has in their minds is that who will utilize the new GDDR5X memory solution. The most obvious contender are discrete graphics cards built by both AMD and NVIDIA. Both companies are on the verge of launching 16/14nm based graphics cards codenamed Polaris and Pascal. Of all the samples which have been showcased, we haven’t seen a HBM based solution as of yet but we can’t really be sure since the samples are in early engineering phase.
    In fact, NVIDIA and AMD both have confirmed in their slides that HBM2 is going to be incorporated in their next generation cards and knowing that NVIDIA is going to have 1 TB/s bandwidth on their Pascal chips which is something only possible with HBM2, we will definitely be looking at HBM2 cards. The HBM standard remains a vital solution for the high-end cards, offering up to 1 TB/s of bandwidth. Even the current HBM1 solution offers more bandwidth than GDDR5X (512 GB/s vs 448 GB/s). But, GDDR5X isn’t necessarily meant to compete against HBM but both solutions are meant to exist for a range of discrete solutions.

    Image Credits: NVIDIA @ Flickr
    Since the last two generations, NVIDIA has offered a 256-bit wide bus solutions on their G**04 GPUs (GK104 and GM204). If cost of the GDDR5X DRAM is marginal, then we would see NVIDIA make a switch to GDDR5X and the switch would be easy since the command protocols for the memory is same. The GDDR5X solution is also a valid option for entry to mid-range offerings so that the higher-end could make use of the HBM standard which makes more sense. Cards such as the Radeon R9 390 and R9 390X offer great value and offer up to 8 GB of GDDR5 VRAM with bandwidth of 384 GB/s. Compared to the flagship Fiji based cards, the R9 390 series are often sighted as more better value. This would be the edge that GDDR5X might have over HBM1 and HBM2 however if mass production is expected to begin in Summer 2016, then we might get to see actual GDDR5X products in the second half of 2016.
    At SC15, NVIDIA pointed out that HBM is a great memory architecture which will be implemented across Pascal and Volta chips but those chips have max bandwidth of 1.2 TB/s (Volta GPU). Moving forward, there exists a looming memory power crisis. HBM2 at 1.2 TB/s sure is great but it adds 60W to the power envelope on a standard GPU. The current implementation of HBM1 on Fiji chips adds around 25W to the chip. Moving onwards, chips with access of 2 TB/s bandwidth will increase the overall power limit on chips which will go from worse to breaking point. A chip with 2.5 TB/s HBM (2nd generation) memory will reach a 120W TDP for the memory architecture alone, a 1.5 times efficient HBM 2 architecture that outputs over 3 TB/s bandwidth will need 160W to feed the memory alone. GDDR5 and GDDR5X themselves face increased I/O power when compared to HBM.
    This is not the power of the whole chip mentioned but just the memory layout, typically, these chips will be considered non-efficient for the consumer and HPC sectors but NVIDIA is trying to change that and is exploring new means to solve the memory power crisis that exists ahead with HBM and higher bandwidth. In the near future, Pascal and Volta don’t see a major consumption increase from HBM but moving onward in 2020, when new GPUs are expected to arrive, we will see introduction of a much more efficient memory interface for the discrete graphics solutions.

    While HBM in comparison to GDDR5 saves space and consumes less power, an interposer design is needed to house the memory stacks and GPU die. A lot more development is required to make a fully functional HBM product and that could be one main reason why we would see cards beneath the high-end stuff based on GDDR5 designs. The HBM2 designs are also entering mass production in early 2016 as announced by Samsung and will allow GPU makers to develop their flagship cards for HPC and Consumer markets. It will be interesting to see the new standard being incorporated in new graphics cards when they launch later in 2016.

    Micron Announces Sampling Of GDDR5X Memory For Faster Next Generation Graphics Cards

    Eventually we're going to see next-generation graphics cards outfitted with GDDR5X memory. It's a process getting to that point, and slowly but surely, things are moving along. To wit, JEDEC ratified the GDDR5X specification back in January of this year, and not even a full month later Micron announced that its GDDR5X program was in "full swing" with sampling to soon follow. Well, that time has come.

    We just got word straight from Micron that it has indeed started sampling GDDR5X memory to clients. That's a big deal because it's one of the last steps in the rather long process of introducing new technology into the consumer market. The next announcement you're likely to hear about GDDR5X memory is that it's making a debut on a graphics card.


    Why does any of this matter? GDDR5X memory pushes data rates to 10-14Gb/s. That's up to double the memory bandwidth of today's GDDR5 devices, and the best part for manufacturers is that it's not a completely new design—the memory architecture is largely the same, which will make transitioning to GDDR5X an easy and cost-effective affair.

    One thing to note is that GDDR5X isn't a replacement to High Bandwidth Memory (HBM). Only AMD is using HBM chips right now, though with the arrival of Pascal later this year, rumor has it NVIDIA will as well, at least on its high-end offerings. It's entry-level and perhaps even mid-range Pascal cards are likely to use GDDR5X memory.

    GDDR5X coming closer to reality, sampling begins to customers

    The dream of higher-bandwidth it a slightly lower cost compared to HBM is coming closer to reality now that Micron has begun shipping samples of their GDDR5X chips to customers for inclusion in prototypes. This means that AMD and NVIDIA are now able to properly test the increase in bandwidth compared to normal GDDR5 and even HBM(2).


    It looks like at the moment they're able to ship two different densities, 8Gb and 16Gb that can allow for VRAM of up to 16GB over a 256-bit wide memory bus. Each chip would be relegated to a single 32-bit channel. Don't fret, however, because even though it's a comparatively small memory bus, the internal changes to the structure still allow for far more bandwidth traveling over that bus. It's akin to increasing the speed limit, despite the lane being the same size. The result is that we could see up to 448Gbps of bandwidth, which is similar to first generation HBM, though without the restrictions on memory die size. Power-consumption, too, has been reduced slightly to offset any increase from higher clock speeds and more memory chips on the board.

    As of right now it looks like both AMD and NVIDIA are interested in using GDDR5X in their next generation products. From the Capsaicin event, we learned that HBM2 will not be making an appearance until Vega even though the first generation HBM has been confirmed to be part of Polaris alongside traditional GDDR5 and GDDR5X memory. NVIDIA on the other hand will be making great use of Micron's faster tech by likely including 8GB of it in their upcoming GTX 1080, which should be revealed at GTC in April.

    Micron Begins Sampling GDDR5X Memory – Production Planned For 2H 2016

    ´Last month, Micron officials stated that they will commence mass production of GDDR5X memory in Summer. Today, the company has started sampling the next generation GDDR5X memory to customers. With sampling initiated, consumers which mostly include GPU manufacturers will be able to leverage the performance of their upcoming graphics cards which are likely to hit market in mid-2016.

    Sampling of a new memory standard is usually the last phase in the process prior to its introduction as a totally complete, consumer-ready product. NVIDIA and AMD are the two major customers which are reviving samples of the new memory chips and will be able to fine tune their graphics cards which will hit the market in a couple of months.
    The first chips that will be hitting production are 8 Gb DRAMs which are the same size as currently available on GDDR5 standard. It can go up to 16 Gb with GDDR5X so we can see graphics cards with even beefier amount of VRAM on board but the latter is planned for production later on. The 8 Gb DRAM chips will comply to the new standard and feature much faster bandwidth and speeds compared to current generation GDDR5 memory. The specifications are mentioned in detailed, below:

    GDDR5X features faster data transfer rates at the same frequencies!
    Micron has officially stated that GDDR5X memory will be going under mass production in summer, this year. This suggests that the yields of the new DRAM will be high and early samples are already achieving speeds of 13 GB/s compared to the 14 GB/s or higher that it is expected to hit when the memory launches.
    Micron is currently ramping GDDR5X to mass production, and will be announcing sample dates later this spring. We plan to be in full volume production this summer. I also hope to give you an update later this year on performance specifications. via Micron

    For those who like to know what difference is between GDDR5 and GDDR5X, we know from the official specifications published by JEDEC the both memory standards are not a whole lot different from each other but they aren’t the same thing either. The GDDR5X solution is built upon the DNA of GDDR5 and has been updated to deliver twice the data rate. There are a lot of design changes that went in developing GDDR5X to achieve the faster transfer speeds, higher bandwidth and in a package that consumers just around the same power or even lower. Micron states that GDDR5X uses around 70% of the energy that is consumed by GDDR5.

    A slide showcasing the benefits of GDDR5X over GDDR5 memory standard.
    The GDDR5X memory supports a 64-bit wide memory access that has double the prefetch against GDDR5 which supports a 32-bit wide memory access. This allows the memory to offer double the bandwidth and at speeds of 1.75 GHz, the GDDR5X memory will achieve data rates of 14 GB/s that will offer bandwidth of 448 GB/s across a 256-bit memory interface. Currently, the fastest GDDR5 solutions like the GTX 980 Ti can achieve a theoretical bandwidth of 336 GB/s while having access to a large 384-bit bus interface clocked at speeds of 1.75 GHz.
    Micron’s GDDR5X program is in full swing and first components have already completed manufacturing. We plan to hit mass production this summer. The team at our Graphics DRAM Design Center in Munich, Germany is doing a fantastic job, too. Not only do we have functional devices earlier than expected, these early components are performing at data rates of more than 13Gb/s! Memory components mature as they move through the development and manufacturing process, so to see first silicon performing at nearly full performance specs was a pleasant surprise—these early results are incredibly promising. Our first generation GDDR5X is an 8Gb (1GB) density manufactured on our 20-nanometer process technology. via Micron

    A detailed chart highlighting the differences between the different memory standard.
    Compared to GDDR5 which can push speeds of up to 8 GB/s data rate per DRAM, the GDDR5X has speeds of up to 14 GB/s. Currently, Micron has achieved their first breakthrough of 13 GB/s on the 20nm process technology which was used to design a 8 Gb (1 GB) density package. Micron officials however believe that due to such good speeds delivered on early samples, their GDDR5X solution has the potential to achieve speeds even beyond 14 GB/s which is currently the maximum data rate suggested by them.
    Based on the results so far, we believe that GDDR5X has the clear potential to achieve speeds of 14Gbps and potentially beyond. via Micron
    Since GDDR5X comes around the same time when first Pascal and Polaris chips will be available to the market, there’s a possibility that we will see the new memory type being embedded on the latest graphics boards. The Pascal and Polaris GPUs have been rumored to feature as much as 8 GB of VRAM with 256-bit (Polaris) and 384-bit (Pascal) memory interfaces. GDDR5X can help a lot to achieve higher bandwidth on the upcoming graphics boards so it will be really interesting to see what graphics card makers have to offer with their next-gen parts.

    Micron Begins to Sample GDDR5X Memory, Unveils Specs of Chips


    This past week Micron has quietly added its GDDR5X memory chips to its product catalogue and revealed that the DRAM devices are currently sampling to partners. The company also disclosed specifications of the chips they currently ship to allies and which potentially will be mass-produced later this summer. As it appears, the first samples, though running at much higher data rates than GDDR5, will not be reaching the maximum data rates initially laid out in the GDDR5X specification.
    The first GDDR5X memory chips from Micron are marked as MT58K256M32JA, feature 8 Gb (1GB) capacity, and are rated to run at 10 Gb/s, 11 Gb/s and 12 Gb/s in quad data rate (QDR) mode with 16n prefetch. The chips use 1.35 V supply and I/O voltage as well as 1.8 V pump voltage (Vpp). Micron’s GDDR5X memory devices sport 32-bit interfaces and come in 190-ball BGA packages with 14×10 mm dimensions. As reported, the GDDR5X DRAMs are manufactured using 20 nm process technology, which Micron has been using for over a year now.
    The GDDR5X memory standard, as you might remember from our previous reports, is largely based on the GDDR5 specification, but has three crucial improvements: significantly higher data-rates (up to 14 Gb/s per pin with potential up to 16 Gb/s per pin), higher and more flexible chip capacities (4 Gb, 6 Gb, 8 Gb, 12 Gb and 16 Gb capacities are supported) and better energy efficiency thanks to lower supply and I/O voltage.
    The first samples of GDDR5X memory chips fully leverage key architectural enhancements of the specification, including quad data rate (QDR) data signaling technology that doubles the amount of data transferred per cycle over the memory bus (compared to GDDR5) and allows it to use a wider 16n prefetch architecture, which enables up to 512 bit (64 Bytes) per array read or write access. However, the maximum data rates of Micron's sample chips are below tose initially advertised, possibly because of a conservative approach taken by Micron and its partners.
    The addition of GDDR5X samples to Micron’s parts catalog has three important implications. First, the initial development of Micron’s GDDR5X memory chips is officially complete and the company has achieved its key goals (to increase performance of GDDR5X without increasing its power consumption). Second, one or more customers of Micron are already testing processors with GDDR5X memory controllers, which means that certain future GPUs from companies like AMD or NVIDIA do support GDDR5X and already exist in silicon. Third, the initial GDDR5X lineup from Micron will consist of moderately clocked ICs.

    Thanks to GDDR5X memory chips with 10 Gb/s – 12 Gb/s data rates, developers of graphics cards will be able to increase peak bandwidth of 256-bit memory sub-systems to 320 GB/s – 384 GB/s. Which is an impressive achievement, because this amount of bandwidth is comparable to that of AMD’s Radeon R9 290/390 or NVIDIA’s GeForce GTX 980 Ti/Titan X graphics adapters. The latter use 512-bit and 384-bit memory interfaces, respectively, which are quite expensive and intricate to implement.

    Micron originally promised to start sampling of its GDDR5X with customers in Q1 and the company has formally delivered on its promise. What now remains to be seen is when designers of GPUs plan to roll-out their GDDR5X supporting processors. Micron claims that it is set to start mass production of the new memory this summer, which hopefully means we're going to be seeing graphics cards featuring GDDR5X before the end of the year.

    Parece-me que esta vai ser o novo satandard a emergir face ao HBM, pelo menos enquanto o HBM não se tornar acessíveol a todos.
    Por outro lado o GDDR5X poupa trabalho, já que é compatível com o anterior esquema da GDDR5 presente nos PCBs das placas.

    SK Hynix GDDR5 8Gbit coming in 2H 2016



    Samsung already has mass production

    Chaps from the memory manufacturers that like to talk to Fudzilla have confirmed that 8Gbit GDDR5 memory will hit volume production in the second half of 2016.

    The 8Gbit memory chips would enable cards with much more memory than the usual 6GB / 8GB but the question remains if this is absolutely necessary. Nvidia did release a Quadro M6000 card with 24GB memory and this one might be based on already available Micron or Samsung 8Gbit memory chips.
    The Quadro M6000 24GB is quite an expensive card, and 24GB GDDR5 memory with 384-bit memory interface can make up to 317 GB/s bandwidth. This might be the first graphics card to use the 8Gbit chips for what we know, but our article focuses on the gaming cards. The gaming cards with GDDR5 8Gbit chips can be expected in the second half of 2016 with possible launch in June 2016.


    At this time, we hardly see any need for 8GB cards, let alone for anything more than that. Even when you are playing with 4K games, you are quite ok for the time being. The high end gamers with $ / €2000 PCs do believe in the future proof concept, where more memory should provide a higher chances of future proof computer.
    If you think about it, Titan X has 24 memory chips with 512 MB each, and the 24 memory chips with 8Gbit density would get you to 1GB per chip, or total of 24GB card. It remains to be seen if such GTX Titan graphics will launch but there is definitely a possibility, at least for leadership and marketing purposes.
    We would not be surprised to see 12GB cards launching with the Pascal GPUs.
