Nvidia RTX 4080 and RTX 4070 rumours suggest we're still a while away from a genuine launch
Proving that Nvidia's RTX 40-series graphics cards are seemingly no nearer an actual release, the rumoured specs for the RTX 4080 and RTX 4070 have changed. Again.
Now, obviously these aren't final, confirmed GPU specifications, just rumoured chip numbers, but the fact that the specs for two of the most important graphics cards of the entire Nvidia next-gen are still fluid would suggest they're still not in manufacturing proper.
Interestingly, it looks like Jen-Hsun giveth and Jen-Hsun taketh away, as the RTX 4070 is reportedly getting 12GB of GDDR6X memory now—as opposed to the 10GB it originally was rumoured to have—while the RTX 4080 is getting a cut to its CUDA core count.
Of course this is all based on the tweets of chatterbox Twitter leaker, Kopite7kimi, who has been throwing numbers around like an over-enthusiastic bingo caller for the past year or so. In the past day or so they have posted updated GPU specs, with potential 3DMark Time Spy Extreme scores to boot.
I'd say the most interesting is the RTX 4070 rumour, suggesting Nvidia has heard the unnecessary clamour for 'moar memories' from the ravening tech hordes unhappy at the prospect of only 10GB of GDDR6 on the third-tier AD104 Lovelace GPU, and thrown them another couple of gigabytes of quick VRAM to keep 'em quiet.
Aside from that, however, the increase to a 192-bit bus is more welcome, and the fact it's supposedly got the speedy 21Gbps memory now, too. But it is also getting a healthy extra dollop of CUDA cores if this latest leak is to be believed. The previous spec held 7168 cores, where the new number's 7680.
