AMD’s secret Zen 3 gaming CPU had 128MB of game-boosting L3 cache but never saw the light of day
A user from the Chinese Chiphell forums shows off AMD's unreleased Ryzen 9 5900X3D, the X3D variant of the Ryzen 9 5900X.
AMD's Ryzen 9 5900X3D, a prototype chip once rumored to be released, boasted an impressive 128MB of L3 cache and was poised to challenge the Ryzen 9 5900X for gaming supremacy. This engineering sample, discovered on the Chiphell forums, showcased 64MB of 3D V-Cache integrated onto one of the two Core Complex Dies, resulting in a 4,649 MHz boost clock.
While the 192MB L3 configuration was also tested on 16-core Zen 3 chips, AMD ultimately opted for an eight-core, single-CCD design for their gaming-oriented Ryzen processors, ensuring optimal performance and minimal cross-die latency.
