Quick Answers

Which GPU is faster for gaming right now?

Radeon R9 M395X is the faster gaming card right now based on the synthetic data we have. It leads by 0.2% in PassMark G3D (5,120 vs 5,111), which is the best performance signal available in this matchup.

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

Radeon R9 M395X 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 and a newer 2015 generation instead of 2014. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon R9 M395X makes the most sense to buy today. It is $400 cheaper on MSRP at $600 vs $1,000, and it leads G3D-per-dollar by 67% (8.5 vs 5.1), so the value case lines up with the gaming result.
