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

2015

Why 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

2019

Why 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.

Quick Answers

Which GPU is faster for gaming right now?
GeForce 845M is the faster gaming card right now. In our data, it leads by 6.1% in average FPS across 50 tracked games in our benchmark data and by 0.8% in PassMark G3D (1,487 vs 1,475), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon 550X 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 14nm process instead of 28nm, and a newer 2019 generation instead of 2015. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Radeon 550X makes the most sense today based on the pricing and value data we have for this matchup. GeForce 845M still makes more sense if max raw gaming performance matters more than value.
