I am having a little confusion and couldn't find a clear cut solution. Is the cache (L1 and L2) size of AMD Radeon HD7660D in APU A10-5800K the same as that of CPU or is it different? The CPU has L1 = 64K and L2 = 4M. As far as i know, both CPU and GPU have their own caches even in case of APU. If they don't share the same caches, can anyone specify how to find these nos. for fused GPU?
