I'm very curious on why games benefit so much from a 50% larger L3 cache, I'm checking the technical aspects of Ryzen 7 9800X3D and Ryzen 9 9950X, L1 and L2 caches are smaller in the X3D one while the L3 cache is bigger. Can someone help me better understand this? Okay, the CPU can move more things to the cache die when building the frames, less memory fetch, but it seems the performance difference is too big (according to the reviews) for +32MB L3 when comparing those two CPUs. 64MB of L3 on 9950X is still A LOT of cache.
