Verdict
NVIDIA Quadro RTX A6000
7.9 / 10 Expert Rating
Still a genuinely useful 48GB workstation card on the secondhand market, even four years after launch - just expect a real gap versus current RTX PRO Blackwell cards in ray tracing and AI performance.
NVIDIA RTX PRO 5000 72GB Blackwell
8.8 / 10 Expert Rating
A smart memory-capacity-focused variant - genuinely useful for teams whose bottleneck is VRAM rather than compute, at meaningfully lower power draw than the flagship.
