GeForce 845M vs Radeon 550X: 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 845M
2015Why buy it
- ✅6.1% more average FPS across 50 tracked games in our benchmark data.
- ✅Draws 33W instead of 50W, a 17W reduction.
Trade-offs
- ❌2015 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌Lower G3D Mark per dollar, at 0 vs 13.5 G3D/$ (Unknown MSRP vs $109 MSRP).
Radeon 550X
2019Why buy it
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 13.5 vs 0 G3D/$ ($109 MSRP vs Unknown MSRP).
- ✅GeForce 845M is already obsolete for modern gaming, so Radeon 550X is the less risky modern option long term.
- ✅More future proof: GCN 4.0 (2016−2020) on 14nm with a newer platform for upcoming games.
Trade-offs
- ❌Lower average FPS than GeForce 845M across 50 tracked games in our benchmark data.
- ❌2019 hardware with 512 MB of VRAM already sits in legacy territory for modern games.
- ❌51.5% higher power demand at 50W vs 33W.
