Ranked guide
Best workstation GPU for AI
Workstation and professional boards, where 48GB of memory loads models no consumer card can hold. Ranked the same way as every other guide: by the largest model each one runs cleanly, then memory, then price.
How we rank
By the largest model each card loads cleanly (quality quantization, no CPU offload, 8K context), then by VRAM, then by price. No benchmark scores and no tokens-per-second claims — we publish speed as a tier, never a number. Full methodology. Pool: Workstation-class GPUs only.

Ranking a card is not the same as checking your machine. Run the exact check for the model you have in mind, or build a full stack from a budget.
