Nvidia tests cooling for GPUs with a power of 600 W


First clues on the TGP of GeForce RTX 50 graphics cards reach us: Nvidia is testing cooling systems.

After the successive release of several models of graphics cards from the GeForce RTX 40 Super family at the start of the year, we are logically turning to the next generation of Nvidia GPUs. Based on the Blackwell architecture, which follows Ada Lovelace, the GeForce RTX 50 graphics cards are expected for 2025. Nvidia could make an exception and launch hostilities with the RTX 5080 at the end of 2024.

Waiting for, Benchlife gives us interesting information on tests carried out by the Greens concerning the cooling of its future products. Nvidia is reportedly working on heat dissipation systems to manage TGP (total graphics power) ranging from 250 to 600 W.

Powerful cooling for demanding GPUs?

If a 600 W TGP can be scary in terms of electricity consumption and therefore the energy bill, it should be remembered that Nvidia can very well aim for very high cooling performance in the laboratory for various reasons, and ultimately market graphics cards that will not reach such power. And if 600 W is really reached, only the GeForce RTX 5090 would be affected, a very expensive product which targets professionals or gamers who have very high financial means.

As a reminder, the GeForce RTX 4090 releases a TDP (thermal envelope) of 450 W. Its maximum TGP can go up to 600 W through overclocking, but this type of scenario is difficult to achieve. So we are already not that far from requiring cooling for 600 W currently.

All in all, the data that should perhaps attract our attention the most is the base power used for Nvidia’s tests: 250 W. Currently, an RTX 4060 displays a TDP of 115 W and a max TGP of 130 W. Several Cases are possible here to explain it:

  • The power of entry-level GPUs could increase considerably, which seems implausible;
  • The tests do not concern the least powerful GPUs, which should be released later than the high-end ones;
  • Nvidia is aiming high during its testing, but final products won’t need as efficient cooling.
