Verdict
AMD Radeon PRO W7800
8 / 10 Expert Rating
A well-balanced mid-flagship workstation card - most of the W7900's VRAM value at a friendlier price.
NVIDIA RTX A5500
7.6 / 10 Expert Rating
A meaningfully better RTX A5000 for a modest premium - a sensible pick if you're shopping the Ampere-generation workstation lineup specifically.
