Verdict
AMD Radeon Pro W6800X
6.2 / 10 Expert Rating
A sensible mid-tier Mac Pro GPU option offering the same VRAM as the flagship for less; still platform-locked with no upgrade path outside that one machine.
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.
