NVIDIA RTX 3080 12GB
The RTX 3080 12GB is a refreshed version of the RTX 3080 with slightly more VRAM (12 GB vs 10 GB) and more CUDA cores. It delivers the same 912 GB/s memory bandwidth as the 3080 Ti for significantly less money used. In 2026, it's one of the best-value fast inference cards for 7-13B models.
Quick verdict
At ~$450-500 used, the RTX 3080 12GB offers incredible memory bandwidth for the price. 7B models run at 50+ tok/s. The 12 GB limit is frustrating but workable. If you find one cheap, it's a solid entry point.
