And energy efficiency is also important.
AMD has officially announced the EPYC 9004 series processors, codenamed Genoa, they are designed for use in servers and data centers. The line of new chips, as in the case of the recently introduced Ryzen 7000, is based on the Zen 4 architecture and is manufactured using a 5 nm process technology.
Each Genoa series processor has twelve 5nm CCD chips (chiplets) with computing cores and one 6nm die with I / O interfaces. Each processor core has 1 MB of L2 cache, which is twice as much as the previous generation EPYC chips based on the Zen 3 architecture. Each CCD chiplet has 32 MB of L3 cache.
The new EPYC Genoa supports up to 6 TB of 12-channel DDR5-4800 RAM, 128 PCIe 5.0 interface lanes, CXL 1.1 and partially CXL 2.0 technologies. The socket for server processors has changed from SP3 to SP5, processors also support BFLOAT16, VNNU and AVX-512.
AMD also plans to release Genoa-X processors with additional V-Cache memory and Bergamo processors based on Zen 4C cores with 128 cores (maximum configuration) in the future. The release plans also include Epyc Siena processors based on the Zen 4 architecture, but for the new SP6 socket. As for the current models, their range, specifications and prices recommended by the manufacturer are collected in a single plate:
As you can see, the base clock frequencies are in the range from 2.25 to 4.1 GHz, and the boost frequencies are from 3.7 to 4.4 GHz. In some models, TDP can reach up to 400 watts. The prices are even more interesting and completely different from the consumer market, which is all too obvious: from 2730 to 11 805 dollars for a processor in a batch of 1000 pieces.
AMD has also been talking a lot about the energy efficiency of the new Genoa processors, pointing to the increase in the cost of maintaining server systems per kilowatt of power consumed over the past year. The manufacturer assured that systems based on EPYC Genoa will be much cheaper in maintenance than systems based on competitive solutions – up to 52%.
