AMD’s secret Zen 3 gaming CPU had 128MB of game-boosting L3 cache but never saw the light of day
A Ryzen 9 5900X3D, if AMD had released it, would surely have given it a run for its money. This comes from AMD integrating 64MB of 3D V-Cache onto one of the two Core Complex Dies (CCDs) inside the chip. The CPU-Z screenshot also shows a 4,649 MHz clock speed, which is likely the boost clock.
