It looks like NVIDIA's refresh of the RTX 3080 graphics card isn't just going to add more VRAM and bus width. CUDA core counts are also said to have gone up towards 8960 coming from 8704 shader cores for the RTX 3080 10GB.
It goes without saying that the GA-102 chip will continue to be used by the card. An expected increased memory bus width of 384-bits will also bring about an increase in memory bandwidth, at 912 GB/s similar to the RTX 3080 Ti (760 GB/s for the RTX 3080).
The RTX 3080 12GB will have a thermal design power of 340-350W, which is almost as high as the RTX 3080 Ti, which has more cores but the same memory configuration. Because the clock speeds are not specified, it is possible that they are the same as those found in the 10GB SKU.
