Quick Answers

Which GPU is faster for gaming right now?

GeForce GTX 1660 Ti is the faster gaming card right now. In our data, it leads by 9.0% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon RX 6600S instead at 13,016 vs 12,747, so for this question the real-game FPS result matters more than the synthetic split.

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

Radeon RX 6600S is the safer long-term pick for 2026 and beyond. The case is simple: the newer feature stack, with FSR 3 (2023) and FSR Frame Generation + AFMF (2023), while GeForce GTX 1660 Ti is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 7nm process instead of 12nm, 28 vs 0 ray-tracing units, and a newer 2022 generation instead of 2019. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GeForce GTX 1660 Ti makes the most sense to buy today. It is $121 cheaper on MSRP at $279 vs $400, and it leads G3D-per-dollar by 40.4% (45.7 vs 32.5), so the value case lines up with the gaming result. If you are mainly targeting 1080p and lighter 1440p, GeForce GTX 1660 Ti is the easier value choice. If you care more about 1080p and lighter 1440p headroom, Radeon RX 6600S has the stronger long-term case.
