❌Lower G3D Mark per dollar, at 0 vs 5.5 G3D/$ (Unknown MSRP vs $600 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

P102-100 is the faster gaming card right now based on the synthetic data we have. It leads by 2.5% in PassMark G3D (3,301 vs 3,221), which is the best performance signal available in this matchup.

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

Radeon 660M 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 16nm, 6 vs 0 ray-tracing units, and a newer 2023 generation instead of 2018. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

P102-100 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, P102-100 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 660M has the stronger long-term case.
