NVIDIA RTX 3070 Ti
The RTX 3070 Ti is a mid-range Ampere GPU with 8 GB of GDDR6X memory at 608 GB/s - notably faster memory than the regular RTX 3070. In 2026, used prices around $300-350 make it a decent option for running 7B models at speed, but 8 GB VRAM is the limiting factor for larger models.
Quick verdict
The 3070 Ti has respectable memory bandwidth for 7B model inference (50+ tok/s), but the 8 GB VRAM ceiling is frustrating. It's only worth considering if found very cheap used - otherwise an Intel Arc B580 (12 GB, $250) is a better AI value.
