Not true. It performs 20-30% better than a RTX A6000 (I have both). Except it has more than 10 times the VRAM. For a comparison with newer Nvidia cards, benchmarks say it does substantially better than a 5070ti, a bit better than a 4080, and a bit worse than a 5080. But once again, it got 30 times the vram amount of the mentioned cards, which for AI workloads are just expensive toys due to lack of vram indeed.
