Radeon 740M vs Radeon HD 7790: Pros, Cons & Final Verdict

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

Radeon 740M

2024

Why buy it

✅Better long-term bet: RDNA 3.0 (2022−2026) on 4nm gives it a newer hardware base for upcoming games.
✅Draws 45W instead of 85W, a 40W reduction.
✅More future proof: RDNA 3.0 (2022−2026) on 4nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than Radeon HD 7790 across 50 tracked games in our benchmark data.
❌Lower G3D Mark per dollar, at 0 vs 20.7 G3D/$ (Unknown MSRP vs $149 MSRP).

Radeon HD 7790

2013

Why buy it

✅3.5% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 20.7 vs 0 G3D/$ ($149 MSRP vs Unknown MSRP).

Trade-offs

❌2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌88.9% higher power demand at 85W vs 45W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 7790 is the faster gaming card right now. In our data, it leads by 3.5% in average FPS across 50 tracked games in our benchmark data and by 1.5% in PassMark G3D (3,090 vs 3,045), so the answer here is pretty clean.

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

Radeon 740M is the safer long-term pick for 2026 and beyond. The case is simple: a 4nm process instead of 28nm, 4 vs 0 ray-tracing units, and a newer 2024 generation instead of 2013. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon HD 7790 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, Radeon HD 7790 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 740M has the stronger long-term case.
