Quick Answers

Which GPU is faster for gaming right now?

GeForce GTX 1660 Ti (móvel) is the faster gaming card right now. In our data, it leads by 74.0% in average FPS across 50 tracked games in our benchmark data and by 3.8% in PassMark G3D (10,128 vs 9,756), so the answer here is pretty clean.

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

Radeon 8040S 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 4nm process instead of 12nm, 16 vs 0 ray-tracing units, and a newer 2025 generation instead of 2019. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon 8040S makes the most sense today based on the pricing and value data we have for this matchup. GeForce GTX 1660 Ti (móvel) still makes more sense if max raw gaming performance matters more than value.
