The RTX 5090 will reportedly require 600 watts of power

Rumors have been circulating about the RTX 5090 for a while, but we’re finally getting a clearer picture of how Nvidia’s flagship RTX 50-series GPU is shaping up. Well-known hardware leaker Kopite7kimi is claiming the RTX 5090, which seems destined to earn a spot among the best graphics cards, will come with an obscene power requirement of 600 watts.

The leaker shared specs for the RTX 5090 and RTX 5080 on X (formerly Twitter). We’ve seen vague claims from Kopite7kimi in the past concerning RTX 50-series graphics cards, but this is the first time the leaker has shared full specs. According to the leak, the RTX 5090 will require 600W of power and come with a staggering 32GB of GDDR7 memory across a 512-bit bus.

We’ve heard murmurs in the past few months that the RTX 5090 could reach as high as 600W, but this is the first time it’s been brought up alongside other specs. The RTX 4090, by comparison, requires 450W of power. However, the 16-pin power connection the RTX 4090 uses is capable of 600W, and it seems Nvidia could max out that connection with the next-gen RTX 5090. Despite the increased power demands, Kopite7kimi still claims the RTX 5090 will use a dual-slot cooler.

The leaker also shared details about the RTX 5080, claiming the GPU will require 400W and come with 16GB of GDDR7 memory on a 256-bit bus. That’s not a massive improvement in specs compared to the RTX 4080 Super, suggesting Nvidia will keep a large gap in performance between the RTX 5090 and RTX 5080 as it did with its RTX 40-series graphics cards.

Nvidia has yet to confirm that the RTX 5090 and RTX 5080 even exist, though we already know quite a bit about the next-gen Blackwell architecture the GPUs will use. Nvidia has already introduced this architecture to the data center, despite the fact that it was forced to delay the release of its enterprise Blackwell GPUs due to a design flaw.

It’s not clear when Nvidia will introduce its next-gen GPUs to gaming PCs. Following Nvidia’s normal release cadence, we would expect to see the GPUs in October or November — however, given the delay in the enterprise sector, it’s possible the GPUs could get pushed back to 2025.

Nearly two years later, AMD’s RX 7000 GPUs don’t even make up 1% of Steam players
RX 7900 XTX and RX 7900 XT on a pink background.

AMD's latest RX 7000 GPUs may be some of the best graphics cards you can buy, but they aren't popular among gamers, at least according to the latest Steam hardware survey. Only one of AMD's RDNA 3 graphics cards even shows up on the survey, with the RX 7900 XTX occupying just 0.37% -- down by 0.03% compared to last month.

It's worth noting that Steam doesn't list every GPU represented in the hardware survey each month, but it at least lists every GPU that represents a decent chunk of players. For context, the lowest-ranking GPU on the list is AMD's RX 5500 XT at just 0.16% of players. Other RX 7000 GPUs like the excellent RX 7900 GRE are likely represented further down, though with a share of only one-tenth of 1% or less.

The Nvidia app just added a feature I’ve wanted for years
A screenshot of the Nvidia app.

Nvidia just released a big update for its Nvidia app. If you're unfamiliar, Nvidia has been slowly integrating features and settings from GeForce Experience, the Nvidia Control Panel, and other apps like FrameView and ICAT into a single application, aptly named the Nvidia app, making it easier to manage your graphics card. And the latest update includes a feature that I've been wanting for years -- driver rollback.

It's a good idea to keep your GPU drivers up to date. New drivers come with performance improvements, as well as specific optimizations for new game releases. Still, driver releases aren't perfect. You can almost guarantee that some drivers on some configurations will run into strange bugs or performance issues. Here's just one example from a Steam user who saw crashes in Ghost of Tsushima after a driver update, and another who saw crashes in Farming Simulator 22. These issues are almost never widespread, but they're bound to happen to some gamers. Driver rollback gets around the problem.

Want an RTX 5090? Prepare to wait a little longer
RTX 4090.

Nvidia's upcoming top GPU is taking its sweet time to make it to the market, and by the sound of it, we won't see it anytime soon. According to a new report from Benchlife, as well as various other sources, Nvidia is planning to unveil the RTX 50-series at CES 2025 in January. This means that the RTX 5090 is unlikely to make an appearance any sooner than three to four months from now. On the upside, we just learned even more about what the card's going to offer.

After a few months of managing expectations, many GPU enthusiasts no longer expect the RTX 50-series to be released this year -- and leakers agree. Following the huge specification leak we got yesterday, at least two new publications (both Benchlife and The Verge) are now claiming that Nvidia won't announce its next-gen GPUs until 2025. Reputable hardware leakers like kopite7kimi have also previously said that early 2025 is the current target.
