AMD officially announces the "EPYC 7000" series for servers such as super high-performance 32-core model which is 47% higher than Intel's 22 core Xeon & super-discount model from 16 core with more than 70,000 yen

Consumer CPU "Ryzen" series adopting AMD microarchitecture "Zen" impressed AMD restoration with high cost performance overwhelming the CPU of Intel. Server for CPU using that Zen "EPYC 7000AMD officially announced the series. The 32 core "EPYC 7601" which is 47% higher than the 22 core Intel Xeon, and 16 cores / 32, which is a performance exceeding the 22 core Intel Xeon in order to rob the enterprise market boasting the high profit margin directly connected with AMD's performance recovery from the absolute champion Intel A lineup including a low-end model "EPYC 7281" showing overwhelming cost performance from threads of 650 dollars (about 72,000 yen) was disclosed.

AMD's Future in Servers: New 7000-Series CPUs Launched and EPYC Analysis

AMD EPYC 7000 Series Server Processors Officially Launched

◆ Outline of EPYC
In EPYC of CPU called codename "Naples" (Napoli) developed for servers, the four Zeppelin dies support 2ch memories with up to 8 cores including two "CPU Complex" (CCX) respectively. Up to 32 cores / 64 threads, 8ch memory support is realized.

The four CCXs are connected with the new interconnect "Infinity Fabric" and have a high bandwidth of up to 42.6 GB / s.

Since EPYC is CPU for server, it corresponds to dual socket. In addition, the CCX crossing the CPU is also connected by the Infinity Fabric, but this bandwidth is 37.9 GB / s maximum.

Infinity Fabric enables high-speed connection between CPU and 3 GPUs. It supports 16 memories per CPU with 8 ch support, and the dual CPU has a maximum capacity of 4 TB with a maximum of 32 memories.

Each Zeppelin die creates two PCI - Express (× 16) links, and the whole CPU has 128 lanes. In the figure below, the green indicates Infinity Fabric, the blue indicates PCI-Express, and the dark blue indicates SATA, which can support 8 SATA in every 16 lanes. In the case of NVMe, it can support up to 32 storages.

Also, because EPYC includes "Sever Controller Hub" which has 4 USB 3.0, SM bus, I 2 C, SPI, eSPI, TPM, GPIO, timer, UART, etc., it is not exactly CPU but SoC It is getting.

◆ EPYC 7000 series
On June 20, 2017 AMD announced the EPYC 7000 series.

Regarding the line-up in advanceleakIt is the same as what was being done. It covers a wide price range from high-end 32 cores / 64 threads "EPYC 7601" to low-end 8 cores / 16 threads "EPYC 7251".

Attention performance is as follows. The 32-core / 64-thread high-end model "EPYC 7601" is up to 47% higher than the Intel 22 core / 44 thread "Xeon E5-2699A V4" with integer operation (SPECint_rate_base 2006) performance ... ...

Floating point arithmetic operation (SPECfp_rate_base2006) performance is over 75% higher.

The memory bandwidth of STREAM Triad is 2.5 times.

EPYC loaded server on exhibition hall.

A demonstration to overwhelm the Intel machine with a test to compile the Linux kernel with eight virtual machines was made.

In addition, AMD is appealing to be superior to competing Intel Xeon E5 V4 models in all price ranges.

Also, even a relatively inexpensive single CPU model is overwhelming rival Intel.

Depending on the model, AMD says that dual CPU Intel Xeon can be sufficiently replaced with a single CPU EPYC.

The price is revealed for some models of EPYC. From the slide below, the low-order model of 32 cores / 64 threads (EPYC 7501) is expected to be $ 3400 (about 380,000 yen). It is also announced that the top model "EPYC 7601" is about 4000 dollars (about 450,000 yen), and Intel Xeon E 5 - 2699 A V 4 (22 cores / 44 threads ) Is likely to be a powerful rival. Also, EPYC has a lower model (EPYC 7401) of 24 cores / 48 threads and $ 650 (about 72,000 yen) as a lower model (EPYC 7281) of 16 cores / 32 threads, It is likely to break Intel's stronghold with its overwhelming cost performance.

High-performance & low-priced EPYC is likely to overwhelm the current Broadwell-EP generation Xeon, Xeon of Skylake-SP generation that is being developed as a CPU for the next generation server and scheduled to be released within 2017 has appeared Until we do, Intel is going to have a hard fight.
