With 80CUs I really don't see it being 500mm².
As I have said with Renoir density you can fit 21B xtors into around 350mm² which is large enough for 80CUs, TMU updates for Ray tracing, 384 bit bus and a bit more cache. We also know that Renoir clocks well and has an excellent power profile.
That would make so much more sense than some 500mm2 80CU part because AMD could use fewer wafers to build the same number of GPUs allowing for more Renoir parts to be built for the laptop OEMs which is a far more important market for AMD.
