GeForce GTX 660M vs Radeon RX Vega 6: Pros, Cons & Final Verdict

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

GeForce GTX 660M

2012

Why buy it

✅100+% more VRAM for high-resolution textures and newer games (2 GB vs Unknown).
✅Radeon RX Vega 6 is already obsolete for modern gaming, so GeForce GTX 660M is the less risky modern option long term.
✅Draws 50W instead of 295W, a 245W reduction.

Trade-offs

❌Lower average FPS than Radeon RX Vega 6 across 50 tracked games in our benchmark data.
❌2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon RX Vega 6

2017

Why buy it

✅200.7% more average FPS across 50 tracked games in our benchmark data.
✅More future proof: GCN 5.0 (2017−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with Unknown vs 2 GB for high-resolution textures and newer games.
❌2017 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌490% higher power demand at 295W vs 50W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon RX Vega 6 is the faster gaming card right now. In our data, it leads by 200.7% in average FPS across 50 tracked games in our benchmark data and by 2.8% in PassMark G3D (1,492 vs 1,452), so the answer here is pretty clean.

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

GeForce GTX 660M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs Unknown of VRAM. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX Vega 6 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p, Radeon RX Vega 6 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce GTX 660M has the stronger long-term case.
