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.


◆Intel
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
GPU: nVIDIA RTX8000
OS:Windows10 pro for workstation


◆ AMD
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
AMD EPYC 7H12
CPU Cooling:LIQTECH TR4 280
MothrerBoard:Asrock rack ROMED8-2T
RAM: 8x 32GB DDR4-2666
SSD: Intel 905P 960GB
GPU: nVIDIA TITAN RTX
OS: Windows10 pro

Test

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?

Thanks

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...
