Rumor: RTX 4070 with 7680 CUDA cores and 12GB G6X 192b memory

Kopite7kimi has an update on RTX 4070 specs.

After a few disappointing rumors about the RTX 4070 getting 10GB and 160-bit memory configuration, NVIDIA may have changed their mind (again) and will launch a 12GB 192-bit model instead. Not only that, but this graphics card would also have faster memory than the previously mentioned 18 Gbps modules. A faster 21 Gbps memory is now rumored to be used by RTX 4070 SKU, same as alleged RTX 4090 and 4080. A wider bus and faster memory will enable 504 GB/s of maximum bandwidth, 36.5% higher than the previous RTX 4070 specs.

Furthermore, the PG141-SKU331 is rumored to feature 7680 CUDA cores, this is actually the full configuration of the AD104 die with 60 Streaming Multiprocessors. Such configuration was previously rumored for RTX 4070 Ti.

Kopite now claims that the 3DMark TimeSpy Extreme performance for such a configuration would increase from 10K points to 11K points, which now means it outclasses GPUs such as RTX 3090 Ti from the current generation.

Nevertheless, the specifications are not set in stone and are likely to change. This does not mean that current specs are wrong, on a contrary. A good example is the RTX 3050 model which had its first internal specs around December 2020. After receiving 3 major specs updates NVIDIA shelved the SKU till January this year. The point is, NVIDIA tends to shuffle the specs a lot and what Kopite is reporting are those frequent internal updates.
