Verdict
AMD Radeon Pro W6900X
6.5 / 10 Expert Rating
The best GPU Apple ever offered for the Intel Mac Pro, but a dead-end platform-locked product with no upgrade path outside that one machine.
AMD Radeon PRO W7900
8.4 / 10 Expert Rating
The best AMD professional GPU for VRAM-hungry workloads, held back only by narrower renderer/AI software support compared to NVIDIA's CUDA ecosystem.
