A Change Is Coming To The Server Room
AMD’s next generation of server chip, EPYC Genoa will be available in just over two weeks. These Zen 4 based chips will offer a variety of new features that sysadmins will appreciate, such as the ability to use DDR5 memory in up to 12 channels. The new chips will also offer PCIe Gen5, connected to the new 6096-pin SP5 socket which will be introduced at the same time.
The naming conventions of the processors have changed, though thankfully not it the same way AMD proposed to change their desktop lineup. You will also need to be aware of their power requirements, as EPYC Genoa will range from a TDP of 260W up to 360W. Assuming that the leaks were accurate, the lineup will range from a 200W, 16 core, 32 thread EPYC 9124 running at 2.60 GHz to 2.70 GHz with 64MB of L3 cache up to the massive EPYC 9754 with 128 cores and 256 threads, all running between 2.0 GHz to 2.15 GHz, It will be well endowed with 384MB of L3 cache, but you will need to deal with a 360W TDP.
The EPYC Genoa chips are expected to contain 12 chiplets, each comprised of eight Zen 4 cores. The lower end SKUs will not have all these chiplets enabled, though they will still support all the features of the high end SKUs.
Get ready. I saw the press release from AMD and confirmed with our Editor-in-Chief Patrick that this is happening. The next-generation AMD EPYC Genoa is officially launching on November 10, 2022.
