AMD Could Release Next Generation EPYC CPUs with Four-Way SMT

AMD has completed design phase of its "Zen 3" architecture and rumors are already appearing about its details. This time, Hardwareluxx has reported that AMD could bake a four-way simultaneous multithreading technology in its Zen 3 core to enable more performance and boost parallel processing power of its data center CPUs. Expected to arrive sometime in 2020, Zen 3 server CPUs, codenamed "MILAN", are expected to bring many architectural improvements and make use of TSMC's 7nm+ Extreme Ultra Violet lithography that brings as much as 20% increase in transistor density.

Perhaps the biggest change we could see is the addition of four-way SMT that should allow a CPU to have four virtual threads per core that will improve parallel processing power and enable data center users to run more virtual machines than ever before. Four-way SMT will theoretically boost performance by dividing micro-ops into four smaller groups so that each thread could execute part of the operation, thus making the execution time much shorter. This being only one application of four-way SMT, we can expect AMD to leverage this feature in a way that is most practical and brings the best performance possible.
AMD isn't the first to implement this kind of solution to its processors. IBM has been making CPUs based on POWER ISA for years now that feature four or even eight-way SMT and they are one of the key reasons why POWER CPUs are so powerful. Nonetheless, we can hope to see more details about Zen 3 core design decisions as we approach 2020 and launch of Milan CPUs.

AMD Commands 30%+ CPU Market Share For 1st Time in 12 Years According to Latest CPUBenchmark Data

AMD's 3rd Gen Ryzen Continues to Crush it in the DIY Hardware Channel - Outsells Intel 4 to 1

It's very important to point out that the cpubenchmark.net database tracks CPUs in use rather than CPUs sold, making it a much heavier needle to move than other indicators. However, once you understand that about the data from cpubenchmark you will find that it is highly consistent with what we’ve been seeing over the past several months. All of AMD’s high-end 3rd generation Ryzen 7 and Ryzen 9 processors are consistently sold-out across every major retailer we’ve seen in North America and Europe. In fact, latest data from Germany’s largest retailer shows AMD outselling Intel CPUs 4 to 1.

Se souberem continuar a aproveitar a arquitectura, podem realmente chegar a números interessantes uma vez que o lançamento do Ryzen 3 será dentro de 7/8 meses e não vejo a Intel a ter uma resposta à altura neste espaço de tempo.

Parece que os tipos encontraram o jackpot com esta arquitectura.

[LPC]

Boas!
Para mim as key features para o sucesso são:

- AM4 e longevidade das boards (pelo menos 3 gerações por socket)
- Bons Desevolvimentos em curto espaço de tempo mas mantendo a mesma compatibilidade
- Boas Features pelo Preço
- Boa Palavra dos Reviewers

Estas combinações ditaram o sucesso do Ryzen 3 até ao momento.

Vamos agora ver como se comporta a AMD avançando para o Zen 3 com os Ryzen 4.

Cumprimentos,

LPC

[MTPS]

A AMD "hit the jackpot" com esta arquitectura. Não esquecer que os Ryzen 3 vão sair já daqui a 7/8 meses!

A AMD "hit the jackpot" com esta arquitectura. Não esquecer que os Ryzen 3 vão sair já daqui a 7/8 meses!

E já há rumores de que vão ter um aumento de IPC de 8 a 10%, e um aumento de velocidade de 100 a 200 Mhz.
Não é um aumento enorme, mas já é muito bom para uma diferença de um ano.

Mais uma vitória para a AMD

AMD will power the UK's ARCHER2 Supercomputer - A massive win for EPYC

UK Research and Innovation (UKRI), the quasi-autonomous non-governmental organisation (QuANGO) that directs UK research funding, has announced that AMD will power the UK ARCHER2 Supercomputer using EPYC processors.

The system will feature 5,848 compute nodes, 748,544 total CPU cores and feature a total of 1.57 petabytes of combined system memory.
This gives each node access to128 Zen 2 CPU cores over two 64-core AMD ROME processors at 2.2GHz. This means that AMD has just sold almost 12,000 flagship-quality EPYC processors to a single user.

The UK's ARCHER 2 supercomputer will be built by Cray and be deployed at the University of Edinburgh, offering an estimated 28 PFLOPs of peak performance.
The system is due to be put into service in May 2020. On May 6th, a period of 30 days of continuous operation will be scheduled to stress-test the system to help resolve any and all issues before the Supercomputer enters full service.
The original ARCHER Supercomputer will end its operations on February 18th 2020, after which the UK's ARCHER 2 system will be installed.

Right now, it is estimated that the ARCHER 2 will be able to offer an 8.7x performance boost for CP2K workloads, 9.5x gains for OpenSBLI, 11.3x enhancements for CASTEP, 12.9x boosts for GROMACS, and 18.0x improvements for HadGEM3.

Below are the specifications of the UK's ARCHER2 supercomputer.

Hardware specifications:

- 28 PFLOP/s peak performance
- 5,848 compute nodes, each with dual AMD Rome 64 core CPUs at 2.2GHz, for 748,544 cores in total and 1.57 PBytes of total system memory
- 23x Shasta Mountain direct liquid cooled cabinets
- 14.5 PBytes of Lustre work storage in 4 file systems
- 1.1 PByte all-flash Lustre BurstBuffer file system
- 1+1 PByte home file system in Disaster Recovery configuration using NetApp FAS8200
- Cray next-generation Slingshot 100Gbps network in a diameter-three dragonfly topology, consisting of 46 compute groups, 1 I/O group and 1 Service group
- Shasta River racks for management and post processing
- Test and Development System (TDS) platform, to be installed in advance
- Collaboration platform with 4 x compute nodes attached to 16 x Next Generation AMD GPUs

Software stack:

- Cray Programming Environment including optimizing compilers and libraries for the AMD Rome CPU
- Cray Linux Environment optimized for the AMD CPU blade based on SLES 15
- Shasta Software Stack
- SLURM work load manager
- CrayPat as profiler
- GDB4HPC as debugger




The UK's ARCHER2 Supercomputer is estimated to cost £79 million. This may be the first of many new Supercomputing design wins for AMD.

Já seria de esperar...a performance dos ROME é monstruosa!

Os fanboys da Intel já andam a arranjar meia dúzias de teorias sobre esses resultados, pelos vistos não acreditam ser possível.
