GeForce GTX 680MX vs Radeon 680M: 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 680MX

2012

Why buy it

✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).

Trade-offs

❌Lower average FPS than Radeon 680M across 50 tracked games in our benchmark data.
❌2012 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌144% higher power demand at 122W vs 50W.

Radeon 680M

2023

Why buy it

✅8.9% more average FPS across 50 tracked games in our benchmark data.
✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅Draws 50W instead of 122W, a 72W reduction.

Trade-offs

❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.

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 8.9% in average FPS across 50 tracked games in our benchmark data and by 1% in PassMark G3D (3,836 vs 3,799), 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 28nm, 12 vs 0 ray-tracing units, and a newer 2023 generation instead of 2012. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon 680M makes the most sense today based on the pricing and value data we have for this matchup.
