Sure, but 8 CUs @ N3P are going to be tiny anyway and don't increase the APUIOD's cost all that much.High-end laptop owners are probably going to use dGPUs anyway.
This is likely mostly a matter of this construct having better PPW and smaller package than using 2x CCD + 4nm IOD, plus probably the main reason for this anyway:
NPUs with 80 TOPs will probably be required for Copilot++ certification, and neither the 12C-CCD nor the desktop IOD will have that.
