Nvidia RTX 4090 could shatter GPU speed records — but at a big cost

It’s a foregone conclusion that Nvidia’s next-gen RTX 40-series will be the most exciting upgrade we’ve seen thus far for its GPUs.

Rumors have already pointed toward the massive performance boost the upcoming boards will deliver, but a new report suggests that the GPU lineup will be even better than previously believed.

As reported by TechRadar, credible technology insider Kopite7kimi — who has been at the forefront of next-gen GPU rumors — recently stated that it should be “easy to reach 2.8GHz, at least not very hard” for Team Green’s AD102 GPU die, which is said to be the chip powering the RTX 4090.

Comparatively, the GeForce RTX 3090 sports a 1.79GHz base clock speed. In any case, it seems the aforementioned 2.8GHz figure and the assumption that it’s not difficult to hit that clock speed is actually an understatement, according to a new message from Kopite.

He has now provided a follow-up to his original tweet by stating that: “I must say we can expect a much higher frequency.”

Naturally, the presumption will now fuel rumors of a base clock speed of at least 3GHz for the RTX 4090. Hardware Times also highlights how custom liquid-cooled models will obviously push that number further.

Even with such unprecedented clock speeds for standard models, the website still believes the peak power draw will remain in the 400 to 450 watts range.

Elsewhere, Hardware Times points out how clock speeds of 3GHz could therefore theoretically see the RTX 4090 variant surpass the 100 TFLOPs limit. We’ve already heard rumors earlier this year regarding this GPU approaching that unheard-of TFLOP mark.

Still, “significant heat generation and an unreasonable power draw” are the drawbacks with such a high TFLOPs count, according to the website. It also reiterates how the RTX 4080 should hit the 50 TFLOPs mark, while the RTX 4070 should exceed 30 TFLOPs.

Either way, Nvidia is reportedly working on a GPU that will require a massive 900 watts of power, so you can only imagine what kind of TFLOP performance that particular video card will offer.

So how does a base boost clock of 3GHz compare with AMD’s own next-gen Radeon 7000-series? We’ll still have to wait and see until both companies officially introduce their new graphics cards. That said, rumors circulating around Team Red’s offerings suggest they may ultimately beat Nvidia in both efficiency and performance. Only time will tell who comes out on top.

Asus’ new RTX 4090 shattered GPU overclocking records, and you’ll be able to buy it soon
Asus ROG Matrix RTX 4090 graphics card.

If you thought that the RTX 4090 was already the best we'll see in this generation, Asus is here to prove you wrong. Nearly a year after the initial launch of Nvidia's top graphics card, Asus is about to release the ROG Matrix GeForce RTX 4090 -- a one-of-a-kind GPU that already has a new world record under its belt.

Nvidia DLSS 3: explaining the AI-driven gaming tech
Cyberpunk 2077 running on the Samsung Odyssey OLED G8.

Nvidia's Deep Learning Super Sampling (DLSS) has been a staple of PC gaming for several years now, but DLSS 3 turns the tech on its head. It promises impossibly high frame rates in demanding games like Portal RTX by using AI to generate frames all on its own.

It's a simple concept, but DLSS 3 is complex. We're here to catch you up on what DLSS 3 is, how it works, and what games you'll find it in.

I tested AMD’s RX 7800 XT against Nvidia’s RTX 4070, and there’s a clear winner

With the release of the Radeon RX 7800 XT and RX 7700 XT, AMD finally set foot in the mainstream gaming sector with its RDNA 3 lineup. Nvidia, its biggest rival, which also makes some of the best graphics cards, was the first to release competing cards with similar performance -- at least on paper. But are Nvidia's options better than AMD's in this generation?

The RX 7800 XT was, from the get-go, said to be the competitor to Nvidia's RTX 4070, but in reality, these GPUs differ both in price and performance. We've tested the RX 7800 XT and compared it to the RTX 4070, and we now know which of these two GPUs is the one to pick.
