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

Radeon 520

2017

Why buy it

✅Draws 50W instead of 100W, a 50W reduction.
✅More future proof: GCN 4.0 (2016−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than Radeon R7 G across 50 tracked games in our benchmark data.
❌2017 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
13% HIGHER MSRP
$78 MSRPvs$69 MSRP
❌Lower G3D Mark per dollar, at 11.2 vs 12.6 G3D/$ ($78 MSRP vs $69 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

Radeon R7 G is the faster gaming card right now. In our data, it leads by 72.6% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon 520 instead at 874 vs 870, so for this question the real-game FPS result matters more than the synthetic split.

Which GPU is the safer long-term pick for 2026 and beyond?

Radeon 520 is the safer long-term pick for 2026 and beyond. The case is simple: a 14nm process instead of 28nm and a newer 2017 generation instead of 2015. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon R7 G makes the most sense to buy today. It is $9 cheaper on MSRP at $69 vs $78, and it leads G3D-per-dollar by 12.5% (12.6 vs 11.2), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, Radeon R7 G is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 520 has the stronger long-term case.
