❌Lower G3D Mark per dollar, at 0 vs 8.4 G3D/$ (Unknown MSRP vs $450 MSRP).

Radeon R9 M485X

2016

Why buy it

✅19.0% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 8.4 vs 0 G3D/$ ($450 MSRP vs Unknown MSRP).

Trade-offs

❌2016 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌400% higher power demand at 250W vs 50W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon R9 M485X is the faster gaming card right now. In our data, it leads by 19.0% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon 680M instead at 3,836 vs 3,801, 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 680M is the safer long-term pick for 2026 and beyond. The case is simple: a 6nm process instead of 28nm, 12 vs 0 ray-tracing units, and a newer 2023 generation instead of 2016. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon R9 M485X 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, Radeon R9 M485X is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 680M has the stronger long-term case.
