See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GeForce 770M

2013

Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

❌Lower average FPS than Radeon 660M across 50 tracked games in our benchmark data.
❌Less VRAM, with 512 MB vs 2 GB for high-resolution textures and newer games.
❌2013 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌87.5% higher power demand at 75W vs 40W.

Radeon 660M

2023

Why buy it

✅13.2% more average FPS across 50 tracked games in our benchmark data.
✅300% more VRAM for high-resolution textures and newer games (2 GB vs 512 MB).
✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅Draws 40W instead of 75W, a 35W reduction.

Trade-offs

❌Fewer clear downsides in this head-to-head, aside from the usual pricing and availability swings.

Quick Answers

Which GPU is faster for gaming right now?

Radeon 660M is the faster gaming card right now. In our data, it leads by 13.2% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce 770M instead at 3,246 vs 3,221, 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 660M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs 512 MB of VRAM, the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 6nm process instead of 28nm, 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?

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