Radeon RX 550X (móvel)

2018

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 108.6 vs 0 G3D/$ ($35 MSRP vs Unknown MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation (2023).

Trade-offs

❌Lower average FPS than Radeon 680M across 50 tracked games in our benchmark data.
❌Older hardware, 2 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.

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 43.7% in average FPS across 50 tracked games in our benchmark data and by 0.9% in PassMark G3D (3,836 vs 3,800), 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: a 6nm process instead of 14nm, 12 vs 0 ray-tracing units, and a newer 2023 generation instead of 2018. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon RX 550X (móvel) 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 RX 550X (móvel) is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 680M has the stronger long-term case.
