The 48-core, 96-thread AMD EPYC 7643 server chip has been tested on Geekbench 4 and has come up with a gigantic multi-core score of 121,080 points. The Zen 3 Milan part also wields 256 MB L3 cache and has clock rates of 2.30 GHz to 3.60 GHz. Astonishingly, AMD has even more-powerful CPUs than the EPYC 7643 waiting in the wings.

EPYC by name and nature as once again a Milan server chip from AMD has been spotted on Geekbench running up a giant multi-core score. We already have details about both the EPYC 7543 and EPYC 7513, and thanks to Tum Apisak we now have an idea of how well the AMD EPYC 7643 can perform. The single-core score of 5,850 points won’t break any records, but the 48-core processor’s 121,080 points in the multi-core benchmark is certainly an eye-opener.

Other details found on the Geekbench listing for the EPYC 7643 chip, which was operating inside a Wiwynn SV302A-U server, include a frequency range that settled at around 3.44 GHz, so closer to the maximum rate for this Milan part. L3 cache was listed at 32.0 MB x8, for a huge total of 256 MB (L2 24 MB). The processor was at an early stepping 1 stage and was part of a system running on Linux OS.

It’s an impressive result by the AMD EPYC 7643 chip that holds up very well against rivals from Intel’s Xeon Platinum series on this particular benchmark. But it appears Team Red has more to come, as there is still the EPYC 7663 48-core part, which will no doubt have a higher TDP than the EPYC 7643 (225 W), and the 64-core, 128-thread EPYC 7763 that have yet to make their likely show-stopping entrances.
