Radeon HD 7400G

2025

Why buy it

✅Better long-term bet: RDNA 3.0 (2022−2026) on 6nm gives it a newer hardware base for upcoming games.
✅Draws 43W instead of 200W, a 157W reduction.
✅More future proof: RDNA 3.0 (2022−2026) on 6nm with a newer platform for upcoming games.

Trade-offs

❌
66.7% HIGHER MSRP
$50 MSRPvs$30 MSRP
❌Lower G3D Mark per dollar, at 5.3 vs 9.0 G3D/$ ($50 MSRP vs $30 MSRP).

Radeon HD 8400

2012

Why buy it

✅Costs $20 less on MSRP ($30 MSRP vs $50 MSRP).
✅Delivers 69.2% more G3D Mark for each dollar spent, at 9.0 vs 5.3 G3D/$ ($30 MSRP vs $50 MSRP).

Trade-offs

❌2012 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌365.1% higher power demand at 200W vs 43W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 8400 is the faster gaming card right now based on the synthetic data we have. It leads by 1.5% in PassMark G3D (271 vs 267), which is the best performance signal available in this matchup.

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

Radeon HD 7400G is the safer long-term pick for 2026 and beyond. The case is simple: a 6nm process instead of 28nm, 28 vs 0 ray-tracing units, and a newer 2025 generation instead of 2012. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon HD 8400 makes the most sense to buy today. It is $20 cheaper on MSRP at $30 vs $50, and it leads G3D-per-dollar by 69.2% (9.0 vs 5.3), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, Radeon HD 8400 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon HD 7400G has the stronger long-term case.
