Processors from 96 to 256 cores and up to 600 W

New arrivals and all fresh, as we usually like. And it is that AMD has revealed through its official leaks its plans for high-performance server processors that will compete with Intel for dominance and performance supremacy in data centers and enterprises. The new ones AMD EPYC 7004 and 7005 they have important news to know and especially dates closer than you think. If you thought Intel had stepped on the accelerator, wait and see what AMD will do.

There is a lot of information available and it helps to be clear about concepts and organize them well mentally. From what we know now, there will be two different outlets focused on two different product lines: SP5 and SP6numerous configurations available and as expected the number of cores and their consumption will be the factor of definition and diversification of AMD towards these.

AMD EPYC Zen 4: two sockets, two architectures, one lens

The epic is not that it goes very hand in hand with AMD, but those of Lisa Su have been keen to make small the blue giant that had subjugated them a few years ago. Knowing the segments of one and the other socket, we will begin by relating the advantages of the lesser of them.

the SP6 socket focuses on an as yet unrevealed microarchitecture, which is responsible for implementing the 3D V-Cover in servers and will therefore house processors of 32 cores up to 64 based in Zen 4where they will have a consumption of 70 watts up to 225 watts. SP6 will be single socket, it will not have 2P, but it 6 channels of DDR5, 96 PCIe 5.0 lanes with 48 lines focused on CXL as well as 8 reserved for PCIe 3.0.

the SP5 socket It is a bit more complex, as it has two product lines, one of which will get an upgrade. We are talking about Genoa and Genoa-X, the latter is the first time it is mentioned and therefore it is special, while the other update branch for SP5 is carried by Bergamo. To shed a little more light we will start with the first two.

Genoa and Genoa-X They differ only in that the second will have 3D V-Cache and will arrive for the fourth quarter of this year. Genoa continues on its current trajectory winning the 96 cores (12 CCDs) by flag with between 200 and 400 watts to his credit where we already know he’s facing delays so that’s going to condition his upgraded version and it’s possible we’ll almost go to 2023.

In addition, we have Bergamo which, with a TDP of 320 to 400 watts increases the number of cores to 128 cores (16 CCDs) with 3D V-Cache, so it will be AMD’s best for this architecture. To get an idea of ​​Bergamo’s potential, each core will have 16 MB of L3, SMT, AVX-512, SDCI, SDXI and an unknown vertical cache, but it will be by far the fastest ever created… For now.

Zen 5 with EPYC 7004 and 7005 pending, will it also experience delays?

The slide quotes him for the fourth quarter 2023 under the Turin architecture, where once again AMD will raise the bar to 256 cores thanks, apparently, to including the 3nm from TSMC. What we do know is that it will be backwards compatible with the sockets named above and they will be a bit of a game changer as they won’t have SMT so they are 256 “pure” hearts.

This seems to rely on its high consumption, since it will once again rise to no less than 600 watts. Rumors claim that it will be the processor with hbm of the highest capacity ever built so we don’t know if it will have 3D V-Cache as such so we’ll really have to wait for a new leak to get more first hand info on these new EPYC 7004s and 7005
