The flagship graphics cards of recent generations have been trending upwards in maximum power consumption. TheRTX 4090can pull more than 450W, theRTX 3090 Ticould do the same, while AMD’sRX 7900 XTXis rated for 355W. Factory overclocked models are typically a bit higher than that. But those are rookie numbers. It’s been reported that Nvidia’s next generation GB200 AI accelerator can pull up to 1,000W.
Clarke’s actual quote is “Our characterization in the thermal side, you really don’t need direct liquid cooling to get to the energy density of 1,000 watts per GPU. That happens next year with the B200.”
Note that he refers to the B200, but there’s actually no B200 on Nvidia’s roadmap. Its next generation flagship enterprise GPU is referred to as the B100. It’s based on theBlackwell architecture. However, there is a GB200, which combines the B100 GPU with the Grace CPU. It’s likely Clarke simply misspoke and is referring to the latter.
Datacenter GPUs are very different beasts to consumer gaming GPUs, where things like fan speeds, physical size and power consumption are secondary considerations compared to outright performance. The GB200 is all about performance. The different variants of Blackwell based accelerators will eventually form the backbone of cloud AI systems in 2025 and beyond.

I can’t imagine we’ll ever see a 1,000W desktop graphics card. That’s really a step too far for a typical ATX PC, but with 450W becoming a new baseline for high end gaming GPUs, I would expect things to take a step up again. The 500W barrier has pretty much come and gone already, and if Nvidia chooses to release an RTX 4090 Ti, I could imagine 600W or more becoming a reality. Just look at theleaked images of a gargantuan quad slot Founders Edition cooler.

Personally, I loathe the idea of cards using that much power. I use a 450W RTX 4090 regularly, and it really does heat up my office room during long sessions. I hate to think what a 600W+ card would do during the warmer months of the year.
No matter what final form the future RTX 5090 takes, it’ll be a hot and power thirsty card. If high end Blackwell based GPUs have TDPs above 500W, we can expect quad slot or AIO cooled cards to become the norm, particularly overclocked models.
Hopefully cards like the RTX 5060 and RTX 5070 keep the excellent power efficiency and performance per watt characteristics of cards like theRTX 4060and recently releasedRTX 4070 Super.
