Will Zen 4 processors eventually offer up to 128 cores?

Broly_X1 on your twitter account usually brings news about upcoming AMD products, and it’s the same now. We are learningthat older information from the Chiphell server about up to 128 Zen 4 processor cores should be true. At the same time, AMD did not state anything like the maximum number of cores in Zen 4 processors, and we have officially confirmed hardly that these processors are really going.-

At the same time, Zen 4 is expected to use eight-core chiplets, thanks to which this image could be created, showing the idea of ​​the ExecutableFix leaker about the form of Genoa processors. Here, however, it is expected that they will have a maximum of 96 cores in 12 chipsets.

In other words, for a 128-core EPYC / Threadripper, AMD would need to fit a total of 16 chipsets on the processor board, and it must be said that there is no problem with this. After all, the socket should be large enough to fit such a number on the substrate, and we must not forget that it should be 5nm chips, which will be potentially smaller than today’s 7nm.

AMD could indeed retain room for maneuver to increase the number of cores by adding more chipsets, according to Intel’s development, although this would have to be taken into account when designing a new I / O chip that is connected to chipsets and needs to be the corresponding equipment in the form of the Infinity Fabric interface.

But the ExecutableFix just mentioned questions this information. He admits that Zen 4 could have up to 128 cores in some cases, but according to him, 96 cores still apply to the EPYC Genoa generation.

So far, we can only wait and see what develops from it and whether in time there will be any evidence that the 128-core Zen 4 is really on the way. We will also see if and how AMD can use its new V-Cache memory in the upcoming server processors, expanding the total capacity of the L3 cache. Thanks to it, it is possible to reach a capacity of 96 MB in the case of Zen 3 chipsets today, ie such a 128-core EPYC could offer an incredible 1536 MB L3 cache, even if AMD does not increase its capacity per chiplet in Zen 4.
