The Zen 4 architecture will become AMD’s next great evolution for the high-performance CPU industry, both for general consumption and for the HEDT (high-performance computing) and server industries. A couple of days ago, we shared in MC an article where we analyzed the most important keys of this architecture, including one of its most relevant advances, the possible increase in the density of cores per chiplet, which it would go from 8 cores in Zen 3 to 16 cores in Zen 4. It’s not confirmed, but it makes sense.
The use of the chiplet in processors aimed at the professional sector, such as AMD’s Threadripper and EPYC, has an important consequence, and that is that these chips tend to be very large, due to the space occupied, horizontally, by each of the chiplets that are interconnected to achieve very high core and thread configurations, a reality that, according to a recent leak that we have seen, will not change with EPYC 7004, the successors of the current EPYC 7003.
In the image we can see a prototype of an AMD EPYC 7004 Genoa processor, designed to work with the new SP socket (LGA-6096), and which would be based on the Zen 4 architecture. This chip will have up to 96 cores and 192 threadsFigures that, together with the IPC improvement that this new architecture will offer compared to Zen 3, should be more than enough to make it the most powerful processor in its class.
Genoa, codenamed EPYC 7004, will be manufactured on TSMC’s 5nm node, although the I / O chip will use the 6nm process. Will offer DDR5 memory support, it will support configurations up to 12 channels, will have a maximum of 128 PCIE Gen5 lanes, and its maximum TDP will be 400 watts. AMD itself confirmed that Genoa will arrive in 2022, although we do not have an exact date yet, and we do not know the exact working frequency that this new generation of high-performance professional processors will have.
With regard to Bergamo, which is a version that falls within the same generation and architecture, its launch is also scheduled for this year. It will use the Zen 4c architecture, and will feature up to 128 cores and 256 threads. It will not be a major leap against Genoa, but its successor, Turin, which will be based on the Zen 5 architecture, does promise to mark an important turning point, as it will have up to 256 cores and 512 threads. Yes, you read correctly, 256 cores in a single socket.
