GeForce 5090 rumored to be a 600w GPU

If we can believe all rumours, NVIDIA is nearing the finalization of its next-generation "Blackwell" graphics cards, specifically the GeForce RTX 5090 and RTX 5080 models. According to sources close to BenchLife, NVIDIA aims to finalize the design specifications for these cards by September. This timeline suggests a possible unveiling at CES 2025, with a market release shortly after. Early information indicates that the RTX 5090 could have a Total Graphics Power (TGP) of up to 550W, a 22% increase over the RTX 4090. The RTX 5080, on the other hand, is expected to feature a TGP of 350W, marking a 9.3% increase from the RTX 4080.

 

Recent leaks from Kopite7kimi suggest that the RTX 5090’s power consumption could potentially reach 600W. Meanwhile, the RTX 5080 could peak at 400W, although these values remain speculative until NVIDIA confirms the official specifications. Sources from cooling module manufacturers indicate that a 400W cooling system was under development but has since been suspended, whereas a 600W module is still progressing.

I believe it.

It's certainly possible, but I'd remind folks pre-release rumors of the 4090 also said "600W+ card" and it released instead as a 450W card.

Yea that's true, but I think the previous rumors were based on real things they were testing out. I bet they're still testing it out and if they can get the thermals to work out without being rediculous, they would probably do it.

I think I might need to upgrade my 850w PSU finally lol

...at least the early (1.10 V max) custom 4090s had a 450 W base and 600 W oc bios right form the factory (same for the founders edition)...even with that one and plenty of cooling, my stock Giga-G-OC vbios would have transient spikes of 670 W+. I actually run the Galax HoF vbios (~670W before spikes) since November '22 on it, and also have (but only tested gingerly) the Asus XOC 1000 W bios. At the end of the day though, the 4090 is so powerful that I actually restrict the power budget to 90% (out of a possible 122 %). 

 

Custom 5090s likely use the same base-PCB as the custom 4090s, perhaps with some upgraded components. The same power on a smaller node with architectural improvements and GDDR7 should yield plenty of additional performance...cooling the hotspots (which have input to the boost algorithm) will be paramount for good sustained performance

Are they going 3nm for Blackwell? Will be interesting to see how this turns out. Part of the massive gains the 4090 enjoyed over Ampere was due to going from Samsung 8nm (a 10nm node), all the way to TSMC Nvidia 4nm (a 5nm node). 

 

I imagine much more of Blackwell's gains will be underlying architecture changes in addition to the switch to GDDR7. In that sense, you guys are right that they could try to push more power again if they aren't gaining much from the move to 3nm from 4nm.

Blackwell (data centre) is a custom 5nm, labeled as 4nm. I believe it’s called 4NP.

 

Consumer GPUs must be the same but I agree with the sentiment. Architecture changes, GDDR7, and other technologies will drive the efficiencies and performance improvements. If consumers GPUs were on a node more advanced than the data centres in today’s AI hype train age, I’d be hella impressed.

It will be interesting to see what the custom PCB vendors will be allowed to get away with in terms of PL for 5090s...many custom 4090s are already above 660W. Hopefully, the 5090s come with 'better' ATX 3.x power connectors (preferably two for the top cards).

 

I have had my 4090 for almost two years and the 7950X3D for just over a year now - I like to build something new but would need to be convinced of the value in terms of extra performance. While I already have CL34 8000 48 GB (below) and also a functional CL30 6400 96 GB profile, MSFS 2024 (release November 19th) has an 'ideal spec' of 64 GB

I don't find the 4090 as performant as I'd like for VR, so I will definitely go for the 5090 but I dont expect it to be flawless in VR either.

It'll be interesting to see what they do, but I'm guessing stock it will not be 600W. 4090 certainly does gain above 450W stock, but it really is in the diminishing returns category for the amount of power needed to push additional performance. Hell, doesn't lose much dropping to 350W. The 450W stock was definitely choses because of the performance to power curve.

Fresh batch of rumours. Edit: Added additional link, hot off the press!

For what it's worth, we don't know what the W rating refers to. I suspect that might be the rating of the cooler (TDP) rather than actual graphics draw (TGP) under full load.

Yeah Tom's Hardware posted the leak too.

Leak claims RTX 5090 has 600W TGP

 

600 watts... that's a BIG power draw!

They're using both terminology interchangeably (TDP and TGP) so it's difficult to say. All we know is based on Ada, it seems unlikely that the products will ship in a configuration where that is default power draw.  Unless its an engineering unit but I would suspect until they announce the products, we'll likely see a change.

 

The other notable point is the raw compute and vram gap between the 5080 and 5090. It's significant! I hope the 5080 is a bit more... performant, regardless of what the specs on paper say. Targeting a 20% boost to current 4090 performance would be ideal.
