Quick Answers

Which GPU is faster for gaming right now?

RadeonT 660M is the faster gaming card right now based on the synthetic data we have. It leads by 1% in PassMark G3D (2,221 vs 2,200), which is the best performance signal available in this matchup.

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

RadeonT 660M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs Unknown of VRAM, the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 6nm process instead of 14nm, and 6 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?

RadeonT 660M makes the most sense today based on the pricing and value data we have for this matchup.
