Do cards with intentionally handicapped FP64 actually use anywhere near their TDP when doing FP64? It's my understanding that FP64 performance is limited at the hardware level--whether by fusing off the extra circuits, or omitting them from the die entirely--in order to prevent aftermarket unlocks. So I would be quite surprised if the card could draw that much power when it's intentionally using only a small fraction of the silicon.
