I mean, TDP vs. TGP shenanigans and all. The 6800 XT is bios-locked to 255 W on default settings like the rumors said, but is rated at 300 W, so I'm assuming it'll be the same as Nvidia's for now.

That tweet is from last year, when the chip was supposed to give 75 TFlops, but if it now performs better, it wouldn't be strange if it also uses more power.

Some of the the more prominent 'leakers' like MLID still says around 450W tops (TGP) https://www.youtube.com/watch?v=uVcJ3X8eU5s around 9:55. Not that it can't happen.. I just don't see it going anywhere near 600W.

Remember when 350 watts seemed like a lot?

I remember when people went crazy over Fermi. How times have changed lol.

Now we need 1000W+ PSUs and probably some air con to go with them

For the past decade pre-Ampere, "650 watt power supply is more than enough."

Now? 1000 Watts power supply? LOL. Need 2000 Watts if you want to future proof it!

Yeah, my 750W PSU was future proofing when I bought it. Now I may need twice that for this next upgrade.

I guess that the insane power consumption numbers are the result of the fake node shrinks we get now. Like TSMC's N4 that Hopper, and maybe Ada, will use, that's just a refined N5.

I remember needing an extra power connector instead of just the AGP/PCIe slot was considered an extreme solution for overclockers early on...

Now, now, take it easy, grandpa. We don't want you to get too excited about this.
