Quick Answers

Which GPU is faster for gaming right now?

Radeon RX Vega M GH is the faster gaming card right now. In our data, it leads by 23.0% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon 780M instead at 6,906 vs 6,548, 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 780M is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs Unknown of VRAM, a 4nm process instead of 14nm, 12 vs 0 ray-tracing units, and a newer 2024 generation instead of 2018. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon 780M makes the most sense today based on the pricing and value data we have for this matchup. Radeon RX Vega M GH still makes more sense if max raw gaming performance matters more than value.
