Looking at the rumoured performance i'm not sure this was ever going to make it into an ITX form factor if the reported numbers are true. It seems to be quite close to 3070 performance in rasterisation and 3060 performance in ray tracing.
This would mean it's very close to nVidia's offering in performance per watt, and the 3070 was never going to run cool enough.
So the standard 6700 might well be the one to watch out for - assuming that's the card that is targeting circa 3060Ti performance.
