A possible AMD EPYC 7004 'Genoa' CPU engineering sample has been spotted within Geekebench 5 database. The sample doesn't provide us with much information if its truly a Genoa chip but there's one aspect that may confirm that it might indeed be the case.

AMD 5nm EPYC 7004 'Genoa' CPU Engineering Spotted Within Geekbench 5: Features 32 Zen 4 Cores, 32 MB L2 Cache, 128 MB L3 Cache & Up To 4.6 GHz Clocks

The leaked chip is identified as an AMD Engineering sample with the '100-000000866-01' codename and it looks very much like an upgraded version of the previous Genoa sample that leaked out back in March.

This specific AMD EPYC Genoa chip is fabricated on the 5nm process node and will rock a total of 32 Zen 4 cores and 64 threads. In terms of clock speeds, the CPU is reported to feature a base clock of 1.20 GHz while the all-core boost is rated at 4.60 GHz.

This is an increase of 35% over the previous chip which was running at a max clock speed of 3.4 GHz. Now, these are preliminary clock speeds and we can't say for sure how well those clocks were being maintained throughout the tests. Our guess is not that good considering the lower scores compared to the 3.4 GHz sample.

As for the cache, the L3 cache remains 32 MB per CCD and this 32 core chip packs four Zen 4 CCDs which will give 128 MB of L3 cache. The L2 cache on the other hand sees a huge bump with a 2x increase over the current Zen 3 design. The AMD EPYC Genoa CPU packs 1 MB of L2 cache per core so that's 32 MB of L2 cache on the chip whereas a 32 core variant within the Zen 3 lineup would feature only 16 MB of L2 cache. Do note that this is only a four-chiplet chip whereas the flagship Genoa chips will carry as many as 12 chiplets for a total of 96 MB L2 cache.

The platform featured 384 GB of memory which should be DDR5 since Genoa rocks a DDR5 IMC rather than DDR4 on existing Zen 3 EPYC CPUs. The Pegatron platform it was tested on featured NVIDIA's A100 80 GB PCIe accelerators. The AMD EPYC Genoa CPUs based on the 5nm process node will be offering up to 96 cores when they land on the new SP5 platform later this year. We are expecting some huge improvement in both single and multi-core performance and this leak is evident of that.
