Rumour has it that Nvidia is developing two slightly upgraded versions of the RTX 5070 and RTX 5070 Ti, both with more video memory.
According to Kopite7kimi on X (formerly Twitter), the RTX 5070 SUPER will pack the GB205-400 GPU, suggesting it’ll have the full GPU specs. This model is expected to come with 6,400 CUDA cores—a modest 4% bump over the original RTX 5070’s 6,144 cores.
The bigger change is in the memory, which is said to jump to 18GB of GDDR7, up from 12GB on the standard 5070.
That said, the memory bus will stay at 192-bit, and the speed won’t change, meaning bandwidth will remain the same at 672 GB/s. The card’s power draw is also getting a slight increase, with a TGP of 275W—25W higher than the non-SUPER version. Don’t expect these new GPUs to launch soon, though. They’ll likely arrive early next year at the earliest.
As for the RTX 5070 Ti SUPER, it’s rumoured to use the GB203-350 GPU, keeping the same 8,960 CUDA cores as the regular 5070 Ti.
The big upgrade here is in memory capacity, which is expected to jump to 24GB thanks to newer 24Gbit (3GB) GDDR7 modules. The memory speed and bus width (28 Gbps, 256-bit) will stay the same, so bandwidth won’t see any improvements.
Power consumption is going up, too, with a TDP of 350W—a 50W increase over the non-SUPER model.
If the leaks are accurate, these SUPER variants will offer more memory but won’t bring major performance leaps beyond that.
Don’t expect these GPUs to drop anytime soon—they probably won’t arrive until early next year at the earliest.
