Quick Answers

Which GPU is faster for gaming right now?

Radeon R9 M295X is the faster gaming card right now based on the synthetic data we have. It leads by 0.8% in PassMark G3D (5,150 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 M295X 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. That still leaves it as the safer long-term option on hardware alone.

Which GPU is the better buy today?

Radeon R9 M295X makes the most sense to buy today. It is $700 cheaper on MSRP at $300 vs $1,000, and it leads G3D-per-dollar by 235.9% (17.2 vs 5.1), so the value case lines up with the gaming result.
