Nvidia just announced an improved RTX 3080 GPU that offers 12GB of VRAM compared to the original, which has 10GB. There are also approximately 3% more CUDA cores, totaling 8960.
The upgrade in the memory translates into 20% more bandwidth also thanks to the wider 384-bit memory bus. As a result, the GPU draws about 30W more power than the original version, which requires 320W. However, Nvidia is still recommending a 750W-rated power supply.
The new variant should be available starting today from select board partners but the pricing remains unknown.
