AMD EPYC 9004 “Genoa-X” and “Bergamo” CPUs SKU lists leaks out, EPYC 9754 features 128 Zen4c cores

Citiraj:

AMD is yet to officially launch its Genoa data-center CPU series. The company also announced it is working on seperate series with 3D V-Cache and also density optimized Zen4c series. Both of those products have been included into the new, quite long, one should add, lineup of server CPUs. The naming convention for 9004 and 8004 series of Zen4 CPUs will be divided into two sockets: SP5 for 9004 series and SP6 for 8004. The new series will go range from 8 to 128 cores, but 112 and 128 configurations will be reserved to Zen4 based Bergamo CPUs. In fact, only the core count will tell customers if they are buying Bergamo or Genoa because the latter simply does not go above 96 cores.

Similarly to Milan-X, the upcoming Genoa-X series with 3D V-Cache will also carry the X moniker, differentiating it from P (1 socket) and F (high frequency) Genoa CPUs. Configurable TDP will vary from 200 to 400W depending on the model, however the high-core count and high-frequency variants are all above 290W. The EPYC 9754 “Bergamo” is to feature 128 Zen4C cores (with a stripped-down L3 cache) and up to 256 MB of L3 Cache. This CPU will boost up to 3.2 GHz and will have a TDP of 360W. With 16 cores fewer, there is EPYC 9734 with identical boost clock but also 40W lower TDP.

AMD is preparing four Genoa-X CPU, offering up to 96 cores, with the flagship part called 9684X featuring 96 cores and massive 1.1 GB of L3 Cache. This part has a TDP of 400W, which is the highest TDP from all 4th Gen EPYC CPUs.

AMD Bergamo next cloud CPUs to pack 160 Cores

Citiraj:

The cloud-oriented lineup succeeding Bergamo will push the core counts as high as 160. In other words, up to 20 eight-core CCDs. That’s a sizable jump from the 128-core Bergamo chips (with 16 CCDs) set to land early next year. The successor to Bergamo will likely leverage the Zen 5c core with a stripped-down L3 cache and lower clocks. These cores will be fabbed eight on the TSMC N4 4nm or the N3 3nm process node, thereby allowing for higher logic densities. Moving to Intel’s roadmap, Sapphire Rapids-SP is slated to land later this year, followed by Emerald Rapids-SP in 2023 (but in reality, 2024). The former will top out at 56 to 60 cores (depending on yields) plus the HBM variants while the latter will allegedly increase it to 64, a far cry from the 96-core powered AMD EPYC Genoa processors. These two Xeon lineups will consist of Golden Cove and Raptor Cove cores fabbed on the 7nm node. Meanwhile, the Sierra Forest family featuring the Gracemont (E-cores) will pack up to 128 cores, putting up a healthy fight against AMD’s Bergamo offerings, that is if they actually launch the same year. The Xeon-next parts should double down on the core front too but it’ll be the launch schedule that will determine their competitiveness.
