Nvidia RTX 4080 and RTX 4070 rumours suggest we’re still a while away from a genuine launch

Evidence that Nvidia’s RTX 40-series graphics cards aren’t seemingly getting any closer to an actual release, rumors about the specs for the RTX 4080 and RTX 4070 have changed. Again.

Obviously these aren’t definitive, confirmed GPU specs, just chip number rumors, but the fact that the specs for two of the core graphics cards across the entire Nvidia next-gen are still running smoothly would indicate they’re still out of date. manufacturing correct.

Interestingly enough, it appears that Jen-Hsun is giving and Jen-Hsun taking away, as the RTX 4070 now reportedly gets 12GB of GDDR6X memory – as opposed to the 10GB it was originally said to have – while the RTX 4080 is discounted. on its CUDA core count.

This, of course, is all based on the tweets of chatterbox Twitter leaker, Kopite7kimi, who has been lying around for the past year as an over-enthusiastic bingo baller with numbers. In the past day, they’ve posted updated GPU specs, with possible 3DMark Time Spy Extreme scores to boot.

I’d say the most interesting is the RTX 4070 rumor, suggesting that Nvidia has heard the needless call for “moar memories” from the grueling tech hordes unhappy with the prospect of just 10GB of GDDR6 on the AD104 Lovelace GPU. from the third row, and throwing them another few gigabytes of fast VRAM to keep them quiet.

Other than that, though, the expansion to a 192-bit bus is more welcome, and the fact that it now also has the fast 21Gbps memory. But it also gets a healthy extra dollop of CUDA cores if we are to believe this latest leak. The previous specification contained 7168 cores, while the new number is 7680.

The opposite has happened with the new future RTX 4080 GPU, which has the latest AD103 chip specification with 9,728 CUDA cores as opposed to the 10,240 promised earlier.

That means the RTX 4080 has 512 cores less, while the RTX 4070 has 512 more cores. Which probably equates to four streaming multiprocessors (SMs), though it probably won’t make a huge difference in the overall gridded performance. However, it can make a difference in ray tracing performance as you gain or lose another four RT cores in the mix.

I’m not a chatterbox, but I need to make some updates. I hope you do not mind. a possible RTX 4080, PG136/139-SKU360AD103-300-A19728FP32256bit 16G 21Gbps GDDR6Xtotal power ~420WTSE ~15000Now I have completed the latest update for 4090, 4080 and 4070.August 5, 2022

Still, the (probably not fully fabricated) Time Spy Extreme scores are tempting, putting the RTX 4070 on par with the RTX 3090 Ti, and the RTX 4080 some 33% higher. In addition to the very best of our last-generation scores, it’s a potential step change in performance.

But you know, all of this means it’s becoming increasingly unlikely that we’ll see more than one RTX 40-series GPU this year, and it probably won’t be the one you want. We’ve spoken to insiders who have said it probably won’t be a big launch this year, capitalizing on expectations that only the hyper-expensive, mostly unattainable RTX 4090 will be the green team’s only truly new graphics card in 2022.

And that’s pretty depressing.
