Graphics playing cards are apparently simply getting larger and greater, and the Nvidia RTX 5090 may simply be essentially the most power-hungry mainstream graphics card of the final decade, at a reported 575 W TDP.
Over on X, leaker hongxing2020 reported the facility consumption of the RTX 5090 in a cryptic tweet, and well-regarded leaker kopite7kimi replied to this with “and RTX 5080 360 W.” These tweets have been initially noticed and reported on by Videocardz.
To place this energy consumption into perspective, the RTX 4090 has a TDP of 450 W, so the 50 collection iteration has a rise of 125W. That is an influence inflation of simply shy of 30%. Apparently, the 21,600 CUDA cores reported within the 5090 can be simply over a 30% bump from the 16,000 current within the 4090 card. Beforehand, this was rumoured to be 600 W and the precise determine may counsel that Nvidia has lastly locked in a quantity, maybe for communication at CES 2025 subsequent week.
For the RTX 5080, this is able to be a rise of simply 40 W, from the 320 W seen within the RTX 4080 graphics card. This was beforehand rumoured to be 400 W so each playing cards are a bit of decrease than anticipated.
Each playing cards use GDDR7, which is much less energy intensive than the GDDR6X seen within the 40 collection, which means that further energy effectivity is getting used elsewhere. Nevertheless, there’s not way more we will say in regards to the first outing of Nvidia’s Blackwell structure as of proper now, with out getting the specifics of the playing cards. We all know that further energy draw is indicative of extra energy from the playing cards themselves, and may anticipate a wholesome bump in efficiency, as you’d from any additional iteration from Nvidia, however we won’t counsel absolutely what that appears like from simply the TDP.
Nevertheless, what we will say from that is that you could be want an influence provide improve if you have not had one in a number of years. In November, Corsair introduced that a few of its PSU line helps next-generation graphics playing cards, which not solely says one thing in regards to the whole energy draw of next-generation rigs however that the connector will keep the identical too.
In the beginning of the 40-series launch, 12VHPWR connectors have been inflicting faults in essentially the most highly effective playing cards so Corsair’s confidence implies it’ll have examined out no matter Nvidia is cooking up with its energy provides. If you’d like a monstrous RTX 5090-equipped rig, you’ll seemingly want an equally monstrous energy provide to assist it, even when it is rather less power-hungry than initially thought.
