Radeon R9 M485X vs Radeon RX 550X (móvel): Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

Radeon R9 M485X

2016

Why buy it

  • 71.0% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

  • No equivalent frame-generation stack like FSR Frame Generation (2023).
  • 2016 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 1185.7% HIGHER MSRP
    $450 MSRPvs$35 MSRP
  • Lower G3D Mark per dollar, at 8.4 vs 108.6 G3D/$ ($450 MSRP vs $35 MSRP).
  • 400% higher power demand at 250W vs 50W.

Radeon RX 550X (móvel)

2018

Why buy it

  • Costs $415 less on MSRP ($35 MSRP vs $450 MSRP).
  • Delivers 1185.4% more G3D Mark for each dollar spent, at 108.6 vs 8.4 G3D/$ ($35 MSRP vs $450 MSRP).
  • Access to a newer frame-generation stack with FSR Frame Generation (2023).
  • Radeon R9 M485X is already obsolete for modern gaming, so Radeon RX 550X (móvel) is the less risky modern option long term.
  • Draws 50W instead of 250W, a 200W reduction.

Trade-offs

  • Lower average FPS than Radeon R9 M485X 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 R9 M485X is the faster gaming card right now. In our data, it leads by 71.0% in average FPS across 50 tracked games in our benchmark data and by 0% in PassMark G3D (3,801 vs 3,800), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon RX 550X (móvel) is the safer long-term pick for 2026 and beyond. The case is simple: native frame generation with FSR Frame Generation (2023), while Radeon R9 M485X has no comparable frame-generation support, a 14nm process instead of 28nm, and a newer 2018 generation instead of 2016. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Radeon RX 550X (móvel) makes the most sense to buy today. It is $415 cheaper on MSRP at $35 vs $450, and it leads G3D-per-dollar by 1185.4% (108.6 vs 8.4), which is enough to swing the recommendation its way. Radeon R9 M485X still makes more sense if max raw gaming performance matters more than value.
