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

Radeon R5 340

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 340 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.

Radeon R7 340

2015

Why buy it

✅50.5% more average FPS across 50 tracked games in our benchmark data.

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.
❌100% higher power demand at 100W vs 50W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon R7 340 is the faster gaming card right now. In our data, it leads by 50.5% in average FPS across 50 tracked games in our benchmark data and by 2.7% in PassMark G3D (960 vs 935), so the answer here is pretty clean.

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

Radeon R5 340 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 340 makes the most sense to buy today. It is priced the same on MSRP at $99 vs $99, and it leads G3D-per-dollar by 2.7% (9.7 vs 9.4), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, Radeon R7 340 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon R5 340 has the stronger long-term case.
