AMD's latest leaked roadmap shows the number of cores available in the company's next generation of server processors. Launched in 2022, AMD Zen 4 server processors are in the EPYC Genoa 7004 and EPYC Embedded 3004 series.
According to this roadmap , Zen 4 processors or at least EPYC processors with this architecture will be released in 2022. The 7004 series processors will probably arrive first in 2022 and then the 3004 series in the first quarter of 2023.
AMD server processors called EPYC Genoa will be equipped with 96 cores and 192 threads, which will be based on the Zen 4 architecture. This architecture is expected to significantly improve the performance of future AMD processors.
According to rumors, the instructions per cycle (IPC) of these new processors will improve by 29% compared to "Milan" CPUs, and of course, in general, we will see a 40% increase in their performance.
AMD goes for 12 CCDs per chip to be able to use 96 cores in EPYC Genoa processors. Each CCD contains 8 cores based on the Zen 4 architecture. This number of cores will mean an increase in socket size, and its overall dimensions will be larger than current EPYC processors.
The thermal design power of these chips is in the range of 120 to 320 watts, which of course can be configured up to 400 watts. These processors will be compatible with the LGA 6096 socket, which becomes the largest socket at the time.
Next-generation AMD server processors will support 128 lines of PCIe Gen 5.0 and 5200 MHz DDR5 RAM. At its highest, these chips can use up to 3 terabytes of RAM with 128GB modules.
The 3004 Series processors also use the Zen 4 architecture and a multi-module solution. These chips will have 32 to 64 cores and their thermal design power will be in the range of 65 to 120 watts.
