Intel's L3 cache is for CPU only, Apple's is propably shared with the GPU. Also some Intel CPU's have 128MB of "L4" cache to primarily speed up the GPU.

- DiabloD3 11y agoIt isn't for CPU only, Haswell and up GPUs can zero-copy their command buffers out of it (thus making a large number of GPU compute situations "free"); they can't usefully use such a small amount of L3 for texture and framebuffer stuff (not like the highly optimized prefetch and caching systems in Radeons and Geforces can; that is sometimes a work of art). But yes, I highly suspect the bigger L3 on these serves the same purpose as the L4 on Crystalwells.
