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 GeForce RTX 5090 D
8.9 / 10 Expert Rating
A very fast card held back only by a few percent of artificially capped performance; still the fastest GeForce card available in its home market.
