Comment on Retrospectively Reverse-Engineering Apple's Neural EngineparentComments−woadwarrior0111hThis one's authored by a human, the other one is authored by Claude.Does the M4 and later ANE expose any additional capabilities, or is it just a higher-performance iteration of the same thing?IIUC, M4 introduced a fast path for INT8 weights and activations (w8a8). M5 Ultra, M6 and A20 have two ANEs.As an aside, the introduction to this article seems to conflate the ANE with the Neural Accelerators (NAX)Yeah, that part is true. NAX cores are matmult accelerators, closer to tensor cores in NVIDIA GPUs.
