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
7 / 10 Expert Rating
One of the most power-efficient 1080p cards of its generation, weak only in ray tracing.
