I am using an RTX2080TI at the moment to run Video Enhance AI. When upscaling PAL DVD to 400% I see approx 75% Load on the CUDA Cores, but the 11 GB of VRAM are completely hogged. The 8 Core 16 Thread Ryzen CPU is not loaded at all and cannot be the bottle-neck.
I plan to replace it with a RTX 3080 or RTX3090 once they are supported.
The 3090 has only a 20% advantage in number of CUDA cores for more than double the price. Will the 10 GB VRAM limit a RTX3080 so the 3090 has more than the 20% advantage? Or is the limit I am seeing with the 11GB VRAM 2080TI in the software stack?
