Hey moderator, thanks for the reply
You or I might not care about power draw, but looking at nvidia’s history of GPUs, it seems clear that for whatever reason, they want to keep their GPUs within a certain TDP (around 150-165W for x80 and 250W for x80ti).
This is a new release and they are competing against themselves, they have no reason to deviate from their historical TDP trend other than to ensure an acceptably higher level of performance over the 10 series cards.
With that in mind, you could even argue that nvidia is already pushing these cards harder than they would ideally have liked in order to meet adequate performance levels. If the 10 series was worse than it is, we might have seen even lower clocked 20 series cards with TDPs more in-line with previous cards than they are currently.
