GeForce GT 520MX vs Radeon R3: 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 GT 520MX

2013

Why buy it

  • Costs $5 less on MSRP ($45 MSRP vs $50 MSRP).
  • 100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).

Trade-offs

  • Lower average FPS than Radeon R3 across 50 tracked games in our benchmark data.
  • 2013 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon R3

2019

Why buy it

  • 26.9% more average FPS across 50 tracked games in our benchmark data.
  • GeForce GT 520MX is already obsolete for modern gaming, so Radeon R3 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

  • Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
  • 2019 hardware with 512 MB of VRAM already sits in legacy territory for modern games.
  • 11.1% HIGHER MSRP

Quick Answers

Which GPU is faster for gaming right now?
Radeon R3 is the faster gaming card right now. In our data, it leads by 26.9% in average FPS across 50 tracked games in our benchmark data and by 7.9% in PassMark G3D (314 vs 291), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon R3 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 2013. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
GeForce GT 520MX makes the most sense to buy today. It is $5 cheaper on MSRP at $45 vs $50, and it leads G3D-per-dollar by 3% (6.5 vs 6.3), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, GeForce GT 520MX is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon R3 has the stronger long-term case.
