Curious about this too. Anything more than 16 GPU cores seems like it'd too big to fit on die (share with CPU cores and everything else), so may need to be a discrete solution.
Would Apple then make discrete GPU solutions using PCIe5? Makes sense for the Mac Pro given the edge cases for requiring multi-GPU solutions.
- ksec 5y ago>Anything more than 16 GPU cores seems like it'd too big to fit on die 32 HP Core with 8 HE Core, 128 GPU Core give you ~650mm inclusive of L2 and SLC. Adding in I/O, NPU, ISP, VPU etc this chip should still be within the reticle limit of ~850mm2.
- tyingq 5y agoFor some very loose comparison, the Fujitsu A64FX is a 60mm square package and has 48 ARM cores and 32Gb of memory, though no GPU cores.

- ksec 5y agoThe A64FX has much smaller cores though using the similar design to the N1. Apple's HP Core are nearly double the die size ( Hence why it is faster, it is a trade off between transistor budget )
- SigmundA 5y agoThey have been talking up the advantages of unified memory so my guess is they will stick with integrated, but I would imagine they will end up supporting AMD or Nvidia discrete to some degree.
