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 GeForce RTX 4090 Laptop GPU
8 / 10 Expert Rating
Still a genuinely fast mobile GPU, and a smart buy at a discount now that Blackwell laptops have taken over the flagship spot.
