See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
GeForce GTX 485M
2011Why buy it
- ✅66.2% more average FPS across 50 tracked games in our benchmark data.
Trade-offs
- ❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
- ❌No equivalent frame-generation stack like FSR Frame Generation (2023).
- ❌2011 hardware with 2 GB 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 21.8 G3D/$ (Unknown MSRP vs $109 MSRP).
- ❌100% higher power demand at 100W vs 50W.
Radeon RX 550X
2018Why buy it
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 21.8 vs 0 G3D/$ ($109 MSRP vs Unknown MSRP).
- ✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
- ✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
- ✅GeForce GTX 485M is already obsolete for modern gaming, so Radeon RX 550X is the less risky modern option long term.
- ✅Draws 50W instead of 100W, a 50W reduction.
Trade-offs
- ❌Lower average FPS than GeForce GTX 485M across 50 tracked games in our benchmark data.
- ❌2018 hardware with 4 GB of VRAM already sits in legacy territory for modern games.
