Verdict

NVIDIA RTX A4500

7.1 / 10 Expert Rating

A solid, unglamorous mainstream workstation card - good value on the refurbished market for CAD work that doesn't need cutting-edge ray tracing or AI performance.

NVIDIA RTX PRO 4000 Blackwell SFF

7.7 / 10 Expert Rating

A genuinely useful niche card - the only realistic way to get 24GB of workstation VRAM into a truly small chassis.
