Suspected lineup of AMD EPYC Genoa CPUs with Zen 4 cores appears online
A possible lineup of AMD’s EPYC Genoa CPUs has been shared on Twitter. It concerns eighteen server CPUs, six of which are still engineering samples. In line with previous rumors, the 4nm CPUs will have a maximum of 96 cores and 192 threads, and a maximum TDP of at least 360W.
Of the twelve CPUs which according to leaker YuuKi-AnS ready for production, there is only one that actually has 96 cores and 192 threads: the EPYC 9654P. This CPU would have a clock speed of 2.00 to 2.15GHz and a TDP of 360W. This top model also has the most cache: 384MB. The boost clock rates are not mentioned.
The EPYC 9174F has the lowest number of cores with sixteen cores, but that means that the 320W TDP fits the highest clock speeds of all models. Those clock speeds vary with this CPU from 3.6 to 3.8GHz. The line-up also mentions two engineering samples with a tdp of up to 400W. The cache on these models is not the 3D V-Cache that some other AMD CPUs have. Genoa-X CPUs with 3D V-Cache will appear next year.
The Genoa-Zen 4 CPUs work with the new SP5 socket. This socket is said to support 128 PCIe Gen 5.0 lanes, or 160 lanes if two sockets are used. In addition, the new platform must support DDR5-5200 memory. According to Wccftech the platform may support twelve DDR5 channels, with two dimms per channel. The AMD EPYC Genoa CPUs are expected to be released in the second half of the year.
