AMD Ryzen 9 7950X3D spotted with dual 32MB 3D V-Cache stacks, huge 192MB total cache

Someone has gotten their hands on an AMD Ryzen 9 7950X3D processor with 3D V-Cache stacks on both Zen 4 core dies, for a total of 192MB cache.

Someone has purchased an AMD Ryzen 9 7950X3D processor with 3D V-Cache stacks on both Zen4 core dies, which is 64MB more L3 cache than a retail 7950X3D chip.

A user posted on Bilibili, with their purported Ryzen 9 7950X3D featuring 192MB of L3 cache, which is 64MB more L3 cache than retail Ryzen 9 7950X3D. The obvious red flags: this could be an error with CPU-Z which lists 192MB, it could be a modification, or something else.

This could be an engineering sample Ryzen 9 7950X3D with 3D V-Cache stacks on both Zen 4 core dies, as the Ryzen 9 7950X3D (and Ryzen 9 7900X3D) feature just one 3D V-Cache stack. Maybe this is a bigger discovery, an engineering sample 7950X3D with 192MB of L3 cache that never hit the market... very cool. Or, to spoil the party, this could just be a simple error.

AMD's flagship Ryzen 9 7950X3D processor features two CCDs on the chip each with 64MB of L3 cache (32MB per CCD) and a single 3D V-Cache stack with 64MB of additional cache. Each and every X3D processor from AMD has a single stack of 3D V-Cache, so this new stack on this purported 7950X3D is a big deal.

But, having more 3D V-Cache isn't just automatically better. There's increased latency for both gaming and professional workloads, which is why the Ryzen 7 7800X3D is the best of all the X3D processors, and my personal recommendation for a new CPU.

AMD's Ryzen 7 7800X3D is a higher performing CPU over the 7900X3D which has a single 3D V-Cache stack on a single 8C/16T CCD. Whereas the 7900X3D and 7950X3D have dual CCDs and a single stack of 3D V-Cache, so if any work is being split between the CCDs (there are more cores and threads, thus bigger, and different workloads) then latency gets in the way, which leads the 7800X3D as the better CPU for gaming.
