AMD EPYC 9664, a beast with 96 cores and 400W TDP


That AMD EPYC 9664 It will be the company’s next flagship in the high-performance server processor market. This processor contains nothing less than 96 cores and 192 threads, and we have already seen benchmarks of the AMD Epyc 9654P with the same number of cores conquering the market. As we shall now see this EPYC 9664 goes even further.

AMD EPYC 9664, the Zen 4 beast with more cores on the market and a TDP of 400W

AMD EPYC 9664The AMD EPYC 9664 retains the characteristics of the 9654P, such as 96 cores and 192 threads or the massive 384 MB L3 cache, but with higher frequencies: we know that the base would start at 2.25 GHz, This is already more than the maximum that 9654P will reach. Everything seems to indicate that it will achieve that 2.35GHz base frequency.

We don’t take into account the turbo frequencies, which would be enough 3.8GHz in this AMD EPYC 9664

Such low clock speeds are normal for server-class processors with such a high number of cores. It’s hard to feed such an animal and that leads to it TDP 400W, are more or less 4W TDP per core, That’s rude, Let’s think of the Ryzen 9 5950X with its 105 W TDP for 16 cores.

amd epyc 9000In addition, the low frequencies are compensated by the excellent AMD Zen 4 IPC. Then, Each core will be quite powerful despite the low frequency. In any case, it is clear that it is a CPU that should be used only where all cores are used, B. to split into virtual servers (VPS).

With 1 core and 2 dedicated threads per machine, you could run 96 virtual machines from a single server and 192 machines if we consider a dual socket server.

As we can see, all new EPYC processors except those with 16 and 24 cores have relatively low frequencies. This is in addition to the fact that TDP and manufacturing feasibility issues are to be expected We don’t have turbo frequencies, not quite known yet, but will reach 3.8 GHz in this AMD EPYC 9664.

Of course you would have to see which turbo works with the 96 cores.

Still, the AMD EPYC 9000 (Genoa) series is destined to become one Hard hit in the server CPU market.

We recommend reading the best processors on the market.

It should be the AMD EPYC 9664 the best x86 processor on the market in terms of multi-core performance. It is very important that AMD remains strong and competitive because there is no longer a single competitor We must also consider the evolution of servers with ARM processors.
