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.
AMD Radeon RX 6600 XT
7 / 10 Expert Rating
A solid mainstream pick if its price and 8GB VRAM allocation match your target resolution.
