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 7800M
7.3 / 10 Expert Rating
A genuinely powerful mobile RDNA 3 GPU, competitive with high-end NVIDIA mobile parts, limited mainly by regional availability outside China.
