Yes, because its basically the same thing. If IHV is telling use that their product's TDP is 400W, that means that it can dissipate 400W, which means it can accommodate GPU with 400W of power consumption. So unless IHV has purposely decided to shoot themselves in the foot by overestimating TDP(*), TDP=power consumption. <- my point * this does happen in some cut down lower chip versions, but it's just a simplification. Overestimating TDP does not happen with major products, when the eyes of the press and everyone else is glued on TDP. Or sometimes IHV can even cheat, and communicate lower TDP to the press, but that's dishonesty, and I am talking about the proper, the best attempt at TDP estimate. Ingame power consumption(averaged across 6-7 reviews) vs TDP. See the trend?
