After a very technical test from the ChipsandCheese site, it’s around a Chinese user to share the results of another Milan X CPU, namely the Epyc 7773X.
4.8 GHz and 1600 MB of cache for a dual socket 7773X?
A Chinese reviewer who was able to get his hands on a dual socket platform and 2 AMD Epyc 7773X processors has shared several tests to show the performance of this new CPU. This way we can make an opinion on the 3D V-Cache and finally know if this technology brings a significant gain.
The processors used in the test are 2 Epyc 7773X, the most high-end version, with 64 cores and 128 threads with frequencies ranging from 2.8 GHz in base and 3.5 GHz in boost in retail versions, on the cache side we are on 768 MB of L3. The system used is a dual socket, we are in the presence of a machine with 128 cores and 256 threads and more than 1.6 GB of L3, cooled by fans Noctua NH-U14S. The whole is coupled with 1TB of DDR4 ECC.
In front of the dual socket (128 cores), the reviewer placed an i9-12900K (16 cores), an Epyc 7T83 (64 cores) and a Xeon 8375c (32 cores). On Cinebench, the 7773X doesn’t really stand out, losing almost 35-40% performance to its counterpart without 3D V-Cache and only 64 cores. This is also close to the performance of an 8375C with 4 times less cores!
The CPU was then run under 3D Mark TimeSpy, where again, despite the addition of the cache, it does not shine and is still slower than the EPYC 7T83.
We also have the right to overclocking, where both processors are pushed to 4.5 GHz on 128 cores, reaching 37615 points on CPU Z, a score that seems low, in comparison a simple Threadripper pro 3995 WX exceeds 30000 points. The processor went up to 4.8 GHz without any “problem”, but could not go above 5 GHz.
Despite the average or even disappointing results, it should be remembered that we are dealing with server processors in ES version and that the 3D V-Cache allows a performance gain in very specific applications. On the other hand, we must qualify the overclocking results which will be the subject of much discussion. Indeed, it is unlikely that the 2 Epyc 7773X could really run at 4.8 GHz, as indicated by the software developer.
