Quick Answers

Which GPU is faster for gaming right now?

CMP 40HX is the faster gaming card right now based on the synthetic data we have. It leads by 3.8% in PassMark G3D (8,749 vs 8,428), which is the best performance signal available in this matchup.

Which GPU is the safer long-term pick for 2026 and beyond?

Radeon PRO W6400 is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 6nm process instead of 12nm, and a newer 2022 generation instead of 2021. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon PRO W6400 makes the most sense to buy today. It is $470 cheaper on MSRP at $229 vs $699, and it leads G3D-per-dollar by 194% (36.8 vs 12.5), which is enough to swing the recommendation its way. CMP 40HX still makes more sense if max raw gaming performance matters more than value.
