    A Intel mostrou outra versão da BG1, desta vez para desktops/workstations.

    Esta consegue fazer uns 45 no Destiny 2. Apesar de que não se sabe os settings.
    Vamos lá ver se com drivers melhores e melhorias do chip, o resultado sobe um bocado.

    Intel 10nm Alder Lake CPUs To Bring Smartphone’s big.LITTLE Philosophy To Desktop

    A very interesting post about Intel's upcoming 10nm-based Alder Lake processors was posted on Chinese PC shopping forums (via @momomo_us) recently. This post was very surprising because not only is Alder Lake quite far out on the horizon (It will be preceded by Rocket Lake which should succeed Comet Lake), it showcases the introduction of a philosophy that has been wildly successful in smartphones: big.LITTLE. It goes without saying, however, that this is just one leak and not substantiated as of this moment and should be taken with a grain of salt.
    Intel's Alder Lake CPUs based on 10++ process will feature 8 big and 8 little cores on the LGA 1700 socket

    While this particular leak is dedicated to desktop processors, if this technology is introduced in Alder Lake then you can be sure it will trickle down to the notebook parts as well - and it is there which should be able to add some serious value. The big.LITTLE philosophy (invented by ARM) allows processor manufacturers to selectively choose a high performance or a low energy cluster depending on need and demand. While it won't make a lot of difference in a desktop environment, it makes an absolutely huge impact in smartphone applications where TDP envelopes are usually constrained and power quite restricted. Before we go any further, here is a screenshot of the relevant slide:

    The three types shown here range from an 8+8+1 configuration (8 big, high powered cores; 8 little, low power cores; and 1 integrated GPU) to a standard 6+1 configuration (only 6 "big" cores with an integrated GPU). The notes also state that Intel is investigating with a 150W design. While it is unclear why Intel is worried about power envelopes in a desktop environment we can expect that the company will allow the big cores to clock fairly high. It will also be interesting to see whether all 16 cores can work in tandem (or only 8 at a time as is usually the case). Judging from the fact that both the 8+8+1 and 6+1 SKUs have the same TDP, however, it likely won't be possible for all cores to operate in tandem.
    Another piece of information that this leak reveals is that Alder Lake will utilize the LGA 1700 socket. Since Comet Lake has already shifted users to LGA 1200, it seems as if the stay on the new socket won't be long (and that Intel won't be following in AMD's lead anytime soon as far as sockets go). If you keep in mind Intel's statements at the Morgan Stanley TMT conference, we also know that Intel plans on aggressively pushing 7nm around the same timeframe Alder Lake is supposed to go live - which might mean that ADL-S is relegated to an experimental platform.
    Intel will be facing stiff competition form a fully mature AMD in 2021 and we will likely be seeing some serious price wars happening as both companies defend their market share. While Intel has a larger margin buffer, AMD's 7nm financial profile is stronger. That said, Intel has historically been able to achieve higher clocks and it remains to be seen whether this is a trend that will hold going into 10nm (roughly equivalent to TSMC's 7nm).
    É apenas um rumor, vindo de um site .....
    Por isso, sal, muito sal.

    Intel Processors Hit with LVI Security Vulnerabilities, Mitigation Hits Performance Hard

    A new class of security vulnerabilities affect Intel processors, which can cause them to leak out sensitive information if probed in a certain way, but that's not the worst news for Intel and its users. The software- or firmware-level mitigation for this vulnerability can inflict performance reductions "ranging from 2x to 19x," according to a report by The Register. A full mitigation for the new Load Value Injection (LVI) class of vulnerabilities requires Intel to redesign software compilers. The vulnerability is chronicled under CVE-2020-0551 and Intel-SA-00334. It is not a remote code execution threat, however, it puts multi-tenant machines, such as physical servers handling multiple tenants via virtual servers.

    "LVI turns previous data extraction attacks around, like Meltdown, Foreshadow, ZombieLoad, RIDL and Fallout, and defeats all existing mitigations. Instead of directly leaking data from the victim to the attacker, we proceed in the opposite direction: we smuggle — "inject" — the attacker's data through hidden processor buffers into a victim program and hijack transient execution to acquire sensitive information, such as the victim's fingerprints or passwords," the reasearchers write in the abstract of their paper describing the vulnerability. Anti-virus manufacturer BitDefender independently discovered LVI and shared its study with Intel. The company could publish its findings in February. Additional technical details are found in the group's website here.

    Comentário interessante nesse link da notícia.

    A própria Intel paga prémios para o pessoal que descobre essas vulnerabilidades... Daí aparecerem tantas xD



    Intel Bug Bounty Program

    Se alguém tiver o link do programa equivalente da AMD, agradeço, queria dar uma olhada mas não encontrei.

    Intel teases Xe-HP graphics processor – ‘Father of All’ GPUs

    The tweet by Intel Graphics presenting Jim Keller (Intel’s senior VP in Technology, Systems Architecture and Client Group and general manager of Silicon Engineering Group) on one photo and Raja Koduri (senior video president, chief architect, general manager for Architecture, Graphics and Software at Intel) in another photo, has generated a lot of attention. The third photograph shows a mysterious looking processor, with a package size estimated at 3700 mm2. That’s a huge device more than likely featuring multi-chip design (chiplets).
    We’ve asked anyone who could have shed some light on the processor because it looked like nothing we have seen so far. A future Xeon, FPGA, a new GPU? Well, it seems that the answer was, in fact, provided by Intel.

    Raja Koduri retweeted the picture with a note ‘beep of all is back’. From there it only took minutes for Wccftech to connect the dots. In Hindi ‘baap’ means father, thus we can say that Intel is teasing ‘Father of all” (GPUs) aka Xe-HP. This is not a marketing term we just came up with. It is a term that was already used Koduri when we was presenting the team behind the Xe HP processor back in December. In other words, Raja confirmed that the GPU is Xe HP.

    It is worth noting that this is likely not Ponte Vecchio because that Graphics processor would rely on Xe-HPC architecture. The Xe-HP is designed for media transcoding, workstation and possibly even gaming. An educated guess is that Xe-HP is NVIDIA Quadro or AMD Radeon Pro competitor.

    Isto é um chip enorme.....

    Parece que o DLSS vai ter concorrência.






    This new AI upscaling technique is called QW-Net. According to the teams, QW-Net is a neural network for image reconstruction, where close to 95% of the computations can be implemented with 4-bit integers.


    “This is achieved using a combination of two U-shaped networks that are specialized for different tasks, a feature extraction network based on the U-Net architecture, coupled to a filtering network that reconstructs the output image. The feature extraction network has more computational complexity but is more resilient to quantization errors. The filtering network, on the other hand, has significantly fewer computations but requires higher precision. Our network uses renderer-generated motion vectors to recurrently warp and accumulate previous frames. This produces temporally stable results with significantly better quality than TAA; a widely used technique in current games.”


    “Concurrent to our work, Xiao introduced a reconstruction technique based on U-Net. Using an optimized inference implementation they reconstruct a 1080p image in 18 to 20 ms on a high-end GPU. In comparison, DLSS reconstructs a 4K image in under 2 ms. Both these approaches can reconstruct images at a higher resolution than the input render.”

    Raja Koduri to Present at Samsung Foundry Forum amid Intel's Outsourcing Efforts

    Intel's chief architect and senior vice president of discrete graphics division, Mr. Raja Koduri, is said to be scheduled to present at Samsung Electronics Event day. With a presentation titled "1000X More Compute for AI by 2025", the event is called Samsung Foundry SAFE Forum. It is a global virtual conference designed to be available to everyone. So you might be wondering what is Mr. Koduri doing there. Unless you have been living under a rock, you know about Intel's struggles with node manufacturing. Specifically, the 10 nm node delays that show the company's efforts to deliver a node on time. The same is happening with the 7 nm node that also experienced significant delays.

    Intel has a contract to develop an exascale supercomputer at Argonne National Laboratory, called Aurora. That supercomputer is using Intel's CPUs and the company's upcoming Xe GPUs. Since the company has problems with manufacturing and has to deliver the products (it is bound by several contracts) to its contractors and customers, it decided to look at external manufacturers for its products, specifically Xe graphics. Being that Mr. Koduri tweeted an image of him visiting Samsung Giheung Fab in Korea, and now presenting at the Samsung Foundry event, it is possible that Intel will tap Samsung's semiconductor manufacturing process for its Xe GPU efforts and that Samsung will be the contractor in charge.

    Intel acquires Nvidia developper of ray tracing and DLSS technology

    Anton Kaplanyan, a former Nvidia researcher, has joined Intel. That information is available on his LinkedIn profile. He will be the Intel AXG Group's Vice President of Graphics Research.
    Kaplanyan established the groundwork at Nvidia for Turing and Ampere's ray tracing capabilities, as well as for deep learning super sampling (DLSS). For example, he is the first to have 'applied machine learning to real-time graphics,' and his brainchild is real-time denoising using one sample per pixel. He was also a principal investigator in Facebook's artificial intelligence and rendering research group. While it is unknown what he will develop at Intel, it is clear that Xe Supersampling (XeSS) will be a significant effort. This is the Intel equivalent of dlss.

    Boas!
    Só espero que a INTEL não vá pelo caminho da Nvidia, e crie mais um sistema fechado para reconstrução de imagem e que tenha que ser de propósito implementado nos jogos para fazer alguma coisa...
    Quanto muito deveria apostar na continuidade do FSR, mesmo que o chame por outro nome...

    Pode ser que a Intel veja a AMD como aliada, contra a nVidia e assim, faça um solução aberta.

    Intel unveils ARC graphics roadmap, Xe-Cores and XeSS super resolution technology



    Intel DG2 GPUs will be build using Xe-Cores, those will be grouped in Render Slices. Each Xe-Core will be build using 16 Vector Engines (256-bit) and 16 Matrix Engines (1024-bit per engine). Under each Xe-Core there is a single Ray Tracing Unit (without a fancy name like AMD’s or NVIDIA’s). Thus, DG2 GPUs will have an equal number of Xe-Cores and Ray Tracing Units. The DG2 GPUs feature Memory Fabric which is a large L2 Cache.Intel has released a block diagram of the flagship DG2 (Arc Alchemist) GPU, the 512EU variant:



    Intel XSS will be powered by DP4a and XMX instructions which are present in either already-released DG1 GPUs (Xe-LP) or the upcoming Intel Xe-HPG series (DG2). The XMX Matrix Engines are the building block of AI acceleration on next-generation Arc “Alchemist” GPUs. Each DG2 chip will feature 16 Matrix Engines and 16 Vector Engines
    Intel discloses that frame render time will be higher than traditional upscaling methods, but it will also be significantly lower than rending native 4K images. Those values are not tied to any numbers, it is just a conceptual diagram.
    Intel XeSS is temporal-based upscaling technology that will account for motion vectors (velocity) and the history of previous frames. This data will be processed by XeSS XMX instructions before they reach postprocessing.
