If this rumor is true, the 7900 X3D would be particularly exciting! Why? Because doubling the L3 cache would result in even more L3 cache per core on a SKU where 12 cores share the same amount of L3 cache as 16 cores do - where each core starts with 33% extra L3 cache.
During its Zen 4 reveal event, AMD announced that the 3D V-Cache variants of the new CPUs are on their way. In line with our previous report about the Zen 4X3D SKUs releasing within six months of the Zen 4 launch, leaker Greymon55 suggests that AMD might take the wraps off the Zen 4 CPUs with 3D cache at CES 2023.
