Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 7900M is the faster gaming card right now. In our data, it leads by 37.7% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce RTX 3070 Mobile instead at 23,025 vs 22,385, 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 7900M is the safer long-term pick for 2026 and beyond. The case is simple: 16 GB vs 8 GB of VRAM, the newer feature stack, with FSR 3 (2023) and FSR Frame Generation + AFMF (2023), while GeForce RTX 3070 Mobile is limited to DLSS 2 Super Resolution (2020) and no comparable frame-generation support, a 5nm process instead of 8nm, and 72 vs 40 ray-tracing units. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX 7900M makes the most sense today based on the pricing and value data we have for this matchup.
