That seems doubtful - TDP is supposed to denominate the necessary cooling of a board ("Thermal Design Power"), and (even with some minor heat output from the necessary voltage conversion) a USB port capable of outputting 25W doesn't increase the need for cooling on the board. Any heat from the power passing through the USB port will be generated in the HMD or whatever unit it's connected to, not on the GPU board. As such, I doubt it affects TDP at all.yeah if you compare 1080s with 2080s then off course. Considering the RTX 2070 will performing between a GTX 1080 and a GTX 1080Ti, I think that's good. BTW the 30W higher power draw is due the USB-C Port I guess.
The reason for the increased TDP is far more likely due to the massive increase in die size and the smaller increase in cores. Even with the process refinement going from 16nm to 12nm (which is really just a minor improvement on the same node), you can't increase die area like they've done here without a power penalty. While the RT and Tensor cores are rumored to take up ~50% of the die, and won't be used for the majority of games, you still have a 21%(Ti)/15%(2080)/20%(2070) increase in CUDA cores with no major process improvement to alleviate the increase. The lowering of base and boost clocks would seem to corroborate this (though those clocks might be lowered to account for throttling while running hybrid RT/Tensor workloads). In other words: we don't know, but increased TDPs definitely don't speak to lower power draw.
I don't suppose you'd care to show us this case? I for one am quite curious.Right. The case I built right now will be definitly not good to sell as a case. When I would want to sell a case I've another project. Maybe I will work on this sometime later. I feel very confident about what I want to do, I understand what it involves. I want people to be able to purchase complete builds from my site anyways at some time later in my life. Why not do it now. I will keep you all updated.
