Ryzen CPUs with 3D V-CacheAt the stage of the ES version, it seems that 3D V-Cache was installed in each of the two CCDs.
YouTube channel invited to AMD’s labGamers Nexus, a prototype CPU was shown there. That is the 16C32T ES version Ryzen 9 5950X3D (AMD Eng Sample: 100-000000059-35_41/35_N).
The existing Ryzen 9 7950X3D and Ryzen 9 7900X3D have 3D V-Cache only on one CCD even if it is 2CCD,The ES version Ryzen 9 5950X3D has 3D V-Cache on each of the two CCDs, and has a total of 192MB of L3 cache.

In addition, 12C24T ES version Ryzen 9 5900X3D (AMD Eng Sample: 100-000000652-01_44/35_Y) was also shown. It also has two 3D V-Cache, for a total of 192MB of L3 cache.

AMD said that Ryzen 9 5950X3D and Ryzen 9 5900X3D were not commercialized for various reasons. However, there was also an opinion that I wanted to do highly productive processing, so I decided to make a 2CCD one (Ryzen 9 7950X3D / Ryzen 9 7900X3D).

According to AMD, having 3D V-Cache on each of the two CCDs will not help improve game performance. For these reasons, it seems that 3D V-Cache was finally installed in only one CCD.
One might imagine that two CCDs with 3D V-Cache would improve performance even more, but unfortunately it doesn’t seem to be that easy.
