See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
GeForce 8400M GT
2014Why buy it
- ✅Costs $99 less on MSRP ($50 MSRP vs $149 MSRP).
- ✅Delivers 173.5% more G3D Mark for each dollar spent, at 1.3 vs 0.5 G3D/$ ($50 MSRP vs $149 MSRP).
- ✅Draws 33W instead of 175W, a 142W reduction.
Trade-offs
- ❌Lower average FPS than RADEON X700 across 50 tracked games in our benchmark data.
- ❌2014 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
RADEON X700
2021Why buy it
- ✅2.0% more average FPS across 50 tracked games in our benchmark data.
- ✅GeForce 8400M GT is already obsolete for modern gaming, so RADEON X700 is the less risky modern option long term.
- ✅More future proof: RDNA 2.0 (2020−2025) on 7nm with a newer platform for upcoming games.
Trade-offs
- ❌Older hardware, 256 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
- ❌198% HIGHER MSRP$149 MSRPvs$50 MSRP
- ❌Lower G3D Mark per dollar, at 0.5 vs 1.3 G3D/$ ($149 MSRP vs $50 MSRP).
- ❌430.3% higher power demand at 175W vs 33W.
