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

GeForce GT 755M SLI

2013

Why buy it

✅15.7% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 16.4 vs 0 G3D/$ ($200 MSRP vs Unknown MSRP).
✅Draws 2W instead of 40W, a 38W reduction.

Trade-offs

❌2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon 660M

2023

Why buy it

✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than GeForce GT 755M SLI across 50 tracked games in our benchmark data.
❌Lower G3D Mark per dollar, at 0 vs 16.4 G3D/$ (Unknown MSRP vs $200 MSRP).
❌1900% higher power demand at 40W vs 2W.

Quick Answers

Which GPU is faster for gaming right now?

GeForce GT 755M SLI is the faster gaming card right now. In our data, it leads by 15.7% in average FPS across 50 tracked games in our benchmark data and by 1.8% in PassMark G3D (3,280 vs 3,221), so the answer here is pretty clean.

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: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 6nm process instead of 28nm, 6 vs 0 ray-tracing units, and a newer 2023 generation instead of 2013. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GeForce GT 755M SLI makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, GeForce GT 755M SLI is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 660M has the stronger long-term case.
