The last item about the parties Zen 4’s V-Cache comes from Greymon55 who put up a cryptic tweet referring to the Ryzen 7000 3D V-Cache CPUs. There are reports of three Ryzen 3D V-Cache CPUs being rumored. Ryzen 9 7950X3D, Ryzen 9 7900X3D And Ryzen 7 7800X3D. Based on the SKUs, it looks like AMD will target the high-end market with V-Cache chips and traditional V-Cache parts could end up in retail later.
We don’t know what kind of SRAM (3D V-Cache) stack will be present on the Zen 4 components. The latest generation of V-Cache Zen 3 processors, such as the Ryzen 7 5800X3D, featured a single Zen 3 CCD with 64 MB LLC stacked vertically above the die. , for the Ryzen 7 7800X3D this may also be true as it will have a single Zen 4 CCD with 8 cores and 16 threads.
However, the Ryzen 9 7950X3D and Ryzen 9 7900X3D could be equipped with two Zen 4 CCDs with 12 cores and 16 cores respectively. We can’t say for sure yet whether AMD will have a single stacked CCD with a 3D cache stack or whether both Zen 4 CCDs will be stacked and it remains to be seen whether AMD will keep the 64MB cache stack or switches.
In any case, if AMD is going to use the existing 64 MB (3D V-Cache) SRAM stack, we have up to 104MB cache on the Ryzen 7 7800X3Das far as 140MB cache on the Ryzen 9 7900X3D and good 144MB cache on the Ryzen 9 7950X3D. That’s a 2.6x increase over the Ryzen 7 7700X, 85% over the 7900X and 80% over the Ryzen 9 7950X, but more importantly, it looks like AMD has reserved the 7800X SKU for the variant.3D.
