NVIDIA’s Blackwell graphics cards of the GeForce variety are on target for later this year, and are set to offer the “biggest ever” generational performance lift from Team Green, if a new rumor is to be believed.

This comes from AGF on X (formerly Twitter), a leaker who has been quiet for some time, but has just appeared back on the scene.

In a fresh tweet (highlighted by RedGamingTech over on YouTube), AGF claims the gen-on-gen performance boost will be the largest stride forward NVIDIA has ever taken – at least in the contemporary era of GPUs, we assume – mainly because Blackwell was initially designed to go up against a monster RDNA 4 MCM flagship graphics card.

Although of course that’s a tack AMD has now abandoned, if the grapevine is correct, with pretty much everyone now believing that RDNA 4 will top out at the mid-range.

Even so, NVIDIA is still going to push hard with RTX 5000 GPUs, AGF believes, because the Blackwell generation is expected to hold the fort against RDNA 5, not just go up against RDNA 4. (With the latter not offering any high-end competition anyway, as noted – but RDNA 5 will, or so we’re told, anyway).

What will the mentioned biggest generational leap entail, then? Well, AGF doesn’t put any figures to this assertion, not even ballpark percentages – but elsewhere we have heard the possibility that the RTX 5090 might be 70% faster than the RTX 4090. At least that’s mentioned as a best-case scenario, we should add as a caveat. (Although the lower-tier Blackwell cards will likely be a very different story, of course).

The RTX 4090 is typically seen as a 60% to 70% leap over the RTX 3090 (though quantifying that precisely depends on a whole lot of variables), so as far as we can tell, the suggestion here is we’re getting a 70% uplift, or maybe a touch more even, from the RTX 5090.
