Via @9550pro‘s Twitter account, we can take a first look at the performance offered by an AMD Epyc 9755. However, this preview is based on the 7-Zip benchmark. Fortunately, we have a comparison with a current-generation Epyc, the 9754.
Epyc 9755: how does it perform on 7-Zip?
In terms of features, the 9755 is a real monster with a total of 128 Zen 5 cores and 256 threads. It also benefits from a massive amount of cache memory, 650 MB in total, with 512 MB of L2, 128 MB of L2 and 10 MB of L1. In terms of frequencies, this model comes with a base speed of 2.70 GHz, rising to 4.10 GHz when turbocharged. In short, a real beast, especially compared with its predecessor, the Epyc 9654, which has :
- 96 Zen 4 cores (not to be confused with the Epyc 9754 with 128 Zen 4C cores)
- 384 MB cache
- 2.4 GHz base speed and 3.7 GHz turbo speed
Nevertheless, the leaker gives us the scores of the Epyc 9754, an equivalent in number of cores, even though it is equipped with 128 Zen 4C cores, efficient cores in AMD’s sauce.
As far as the scores are concerned, we logically find ourselves with a doped 9755, with a decompression rate of 4,445,781 KB/s, compared with 2,221,490 KB/s for its opponent. The Zen 5 model is therefore twice as fast, and the same applies to compression, where the new-generation Epyc boasts 346,409 KB/s compared with 171,643 for its rival.
However, it would have been interesting to see the figures for the Epyc 9654, the older generation model. So be careful…
