Quick Answers

Which GPU is faster for gaming right now?

Radeon PRO W6600X is the faster gaming card right now. In our data, it leads by 22.3% in average FPS across 50 tracked games in our benchmark data and by 3.3% in PassMark G3D (13,113 vs 12,692), so the answer here is pretty clean.

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

Radeon PRO W6600X is the safer long-term pick for 2026 and beyond. The case is simple: 8 GB vs 6 GB of VRAM, the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 7nm process instead of 12nm, and 32 vs 0 ray-tracing units. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce GTX 1660 SUPER makes the most sense to buy today. It is $470 cheaper on MSRP at $229 vs $699, and it leads G3D-per-dollar by 195.4% (55.4 vs 18.8), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and lighter 1440p, GeForce GTX 1660 SUPER is the easier value choice. If you care more about 1080p and lighter 1440p headroom, Radeon PRO W6600X has the stronger long-term case.
