✅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 G3D Mark per dollar, at 0 vs 14.9 G3D/$ (Unknown MSRP vs $250 MSRP).
❌100% higher power demand at 50W vs 25W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon 680M is the faster gaming card right now. In our data, it leads by 1.3% in average FPS across 50 tracked games in our benchmark data and by 3.1% in PassMark G3D (3,836 vs 3,720), so the answer here is pretty clean.

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: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 6nm process instead of 12nm, 12 vs 0 ray-tracing units, and a newer 2023 generation instead of 2020. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GeForce MX450 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 MX450 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 680M has the stronger long-term case.
