At the Wells Fargo 6th Annual 2022 TMT Summit., AMD’s CTO Mark Papermaster shared some relevant information about the EPYC Bergamo Zen 4c processor and the Instinct MI300 APU.
AMD EPYC Bergamo is optimized for compute-intensive applications, targeting ARM server processors. With up to 128 cores, EPYC Bergamo is targeting Xeon processors using HBM, as well as higher core-count ARM server products from Apple, Amazon, and Google. It will use the same SP5 socket as the current Genoa, the difference between the two is that Genoa is optimized for higher clocks, while Bergamo has more cores and is optimized for higher throughput work.
AMD said that EPYC Bergamo will ship in the first half of 2023, and use the same code as Genoa, but the code is half the size of Genoa. Since this processor competes with ARM processors, the peak clock is not particularly important, but a certain number of cores is required to ensure throughput. An example of a workload for Bergamo is Java, where the extra cores can definitely come in handy, and Bergamo’s successor, the TCO-optimized Siena series on the SP6 platform, will expand AMD’s key role in TAM growth in the server space.
The Genoa-X with 3D V-Cache technology will be put into production from the beginning of the first quarter to the end of the third quarter of 2023. The release time is probably in the middle of 2023. The current Milan-X has an L3 cache of up to 768MB, and the number of cores of Genoa-X has increased from 64 to 96, so its L3 cache capacity will exceed 1GB, so the SP5 platform will have three different EPYC processors.
