See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
GeForce GT 520MX
2013Why 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
2019Why 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$50 MSRPvs$45 MSRP
