Verdict
AMD Instinct MI210
7.3 / 10 Expert Rating
A practical, PCIe-slot-friendly way to get CDNA 2 compute into a standard server, useful for smaller HPC and AI deployments, but clearly the entry point of its generation next to the dual-die MI250X and now well behind the MI300 series.
NVIDIA RTX A4000
7.2 / 10 Expert Rating
Still one of the best VRAM-per-slot workstation cards for CAD and inference work; not the pick for gaming, but excellent at what it's built for.
