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

GeForce GTX 660

2012

Why buy it

✅Costs $221 less on MSRP ($229 MSRP vs $450 MSRP).
✅Delivers 87.9% more G3D Mark for each dollar spent, at 17.6 vs 9.4 G3D/$ ($229 MSRP vs $450 MSRP).
✅50% more VRAM for high-resolution textures and newer games (3 GB vs 2 GB).
✅Draws 140W instead of 250W, a 110W reduction.

Trade-offs

❌Lower average FPS than Radeon Ryzen 7 6800U across 50 tracked games in our benchmark data.
❌2012 hardware with 3 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon Ryzen 7 6800U

2020

Why buy it

✅170.0% more average FPS across 50 tracked games in our benchmark data.
✅GeForce GTX 660 is already obsolete for modern gaming, so Radeon Ryzen 7 6800U is the less risky modern option long term.
✅More future proof: RDNA 2.0 (2020−2025) on 7nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with 2 GB vs 3 GB for high-resolution textures and newer games.
❌Older hardware, 2 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌
96.5% HIGHER MSRP
$450 MSRPvs$229 MSRP
❌Lower G3D Mark per dollar, at 9.4 vs 17.6 G3D/$ ($450 MSRP vs $229 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

Radeon Ryzen 7 6800U is the faster gaming card right now. In our data, it leads by 170.0% in average FPS across 50 tracked games in our benchmark data and by 4.6% in PassMark G3D (4,225 vs 4,040), so the answer here is pretty clean.

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

Radeon Ryzen 7 6800U 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 7nm process instead of 28nm, 60 vs 0 ray-tracing units, and a newer 2020 generation instead of 2012. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GeForce GTX 660 makes the most sense to buy today. It is $221 cheaper on MSRP at $229 vs $450, and it leads G3D-per-dollar by 87.9% (17.6 vs 9.4), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, GeForce GTX 660 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon Ryzen 7 6800U has the stronger long-term case.
