Aren‘t they based on Turing with the exception of the top SKU ?An RTX 3090 gets around 120 MH/s at 300W or so, which suggests that if the chip layout really is like that, then it's clocked to something like 400 MHz - which doesn't make any sense at all. I think I'll stick with my original assumption that the CMP HX range is simply made from duff GA10x chips and be disappointed with the promo die shot appearing to be nothing more than an intern's vivid imagination with Photoshop.
That would explain the poor hash rate / power consumption compared to RTX 3xxx cards.
Still don‘t see who would buy these mining cards considering very low resale value unless they are priced very attractively.
