Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 7800M is the faster gaming card right now. In our data, it leads by 3.7% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce RTX 3080 Mobile instead at 16,214 vs 15,984, 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 7800M is the safer long-term pick for 2026 and beyond. The case is simple: 12 GB vs 8 GB of VRAM, the newer feature stack, with FSR 3 (2023) and FSR Frame Generation + AFMF (2023), while GeForce RTX 3080 Mobile is limited to DLSS 2 Super Resolution (2020) and no comparable frame-generation support, a 5nm process instead of 8nm, and 60 vs 48 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 7800M makes the most sense today based on the pricing and value data we have for this matchup.
