Suspected specs AMD EPYC Genoa CPUs with Zen 4 cores appear online – Computer – News

The presumed specifications of AMD’s EPYC server processors codenamed Genoa and Zen 4 cores have surfaced online. The architecture would support up to 96 cores and 192 threads, supplemented by 12-channel DDR5-5200 memory and PCIe 5.0.

Of information comes from Twitter account ExecutableFix, where unannounced data about CPUs has appeared before. So placed last year, the user prematurely tested the specifications of AMD’s Ryzen 5000 laptop processors that turned out to be correct. Officially, AMD has not yet released any information about the AMD EPYC Genoa CPUs with Zen 4 cores. The company did make it clear earlier that the Genoa generation will appear next year and will be made on a 5nm process. These will be AMD’s first server processors with Zen 4 cores; the next generation, the AMD EPYC Milan server processors with Zen 3 cores, will not be released until next month.

The 96 cores would be made possible by a design of twelve chips with eight cores each, supplemented by a separate I / O die. That would mean that AMD would not further increase the number of cores per chiplet, but would be able to increase the total number of cores by integrating more chips. ExecutableFix places an image what the Genoa design could look like, which could be a more square design.

According to his information, there will be at least a new socket. In addition, the Genoa-EPYC server processors would support the PCIe 5.0 interface with 128 lanes, or 160 lanes in a two-socket configuration. The tdp would come out at 320W; that’s 40W higher than the upcoming Milan and current Roman CPUs with Zen 2 cores. The tdp could be configured with the Genoa CPUs for a maximum of 400W.

The new Genoa cores will appear in the El Capitan-supercomputer. This would have a computing power of 2.2 exaflops, which is much higher than the current most powerful supercomputer. In the context of this El Capitan supercomputer, AMD said earlier that the EPYC Genoa processors with its Zen 4 cores ipc will then deliver the upcoming Milan processors, but it is still unknown how big this improvement will be.
