28Core Intel Xeon-W vs 64Core AMD 7H12 EPYC

I got a 64-core EPYC 7H12.
I compare it with Intel Xeon-W3275M former my workstation CPU.
First, the Xeon-W 3275M has omitted the multi-socket function and got 64-lane PCI-E. On the other hand, EPYC has 128-lane PCI-E and has high performance, so both are very attractive CPUs as Workstation CPUs.

The Xeon W3275M is very similar to the Xeon Platinum 8280 with the main differences being the elimination of multi-sockets and an increase in the number of PCI lanes.
The clock is 4.6GHz according to ITBM3.0, but it is very rare to achieve that clock. Therefore I am disabling C-states and increasing the response. In that case, the maximum clock is 3.2 GHz.

〇 Test Configuration
Intel Xeon-W 3275M
CPU Cooling:Asetek 690LX-PN
MothrerBoard:SuperMicro X11SPA-T
RAM: 6x 32GB DDR4-2666
SSD: Intel 900P 480GB
OS:Windows10 pro for workstation

The EPYC 7H12 is a 7742 overclocked for some special customers. The clock is 3.3GHz and it is a CPU like the Ryzen Thread ripper 3990X. Rome's PCI-E gen4 is attractive, but at the moment there is no attractive device, but products such as Samsung 980 PRO and Nvidia Amper titan will come out soon.

〇 Test Configuration
CPU Cooling:LIQTECH TR4 280
MothrerBoard:Asrock rack ROMED8-2T
RAM: 8x 32GB DDR4-2666
SSD: Intel 905P 960GB
OS: Windows10 pro


①: I tested Cinebench R15 as a classic CPU benchmark.

As a result, the Xeon-W 3275M is 4306cb, while the EPYC 7H12 is 9551cb, which is more than double score. This is natural considering the number of cores, but in reality, with a 24-core EPYC 7402P, we obtained a performance of 4621cb, so AMD Rome is superior as a base performance.

②: Next, I did a 7-Zip compression/decompression test.
EPYC 7H12 compressed 164000 MIPS/decompression 196000 MIPS. Xeon W-3275M compression 157300 MIPS/decompression 166000 MIPS.
In this test, only 64 cores can be used, so the difference from 7H12 is not large.

③ Finally, I did some tests at AIDA.

CPU Queen is an AVX and AVX2 integer arithmetic test.
The EPYC 7H12 was 320659, and the Xeon W-3275M 165005 was CPU Queen. The difference in the number of threads is very large.

CPU PhotoWorxx is a test that attaches great importance to the performance of the physical core in the AIDA test.
EPYC 7H12 was 91143 MPixel / s, Xeon W-3275M was 74563 MPixel / s.

What about CPU AES?
EPYC 7H12 was 411350 MB / s, Xeon W-3275M was 100475 MB / s. This test seems very advantageous to the ZEN CPU.

More detailed tests will come later.

Finally, my recommendation for 2020 is EPYC 7402P. This CPU is very cheap but has a very high clock in this segment and has a lot of cores. More appeal will be created when PCI 4.0 becomes available.

any required tests?

I want to know how you got a 7H12!
Hi Patrick
STH news always entertains me.

My EPYC 7H12 was pulled from a Dell server for a My mini DGX A100 project.o_O
Currently, Tray is sold at Newegg.
I keep searching for EPYC 7F72 BOX but I still can't find stock...
