GeForce 8400M GT vs RADEON X700: Pros, Cons & Final Verdict

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

GeForce 8400M GT

2014

Why 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

2021

Why 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.

Quick Answers

Which GPU is faster for gaming right now?
RADEON X700 is the faster gaming card right now. In our data, it leads by 2.0% in average FPS across 50 tracked games in our benchmark data and by 9% in PassMark G3D (73 vs 67), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
RADEON X700 is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 7nm process instead of 28nm, 36 vs 0 ray-tracing units, and a newer 2021 generation instead of 2014. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
GeForce 8400M GT makes the most sense to buy today. It is $99 cheaper on MSRP at $50 vs $149, and it leads G3D-per-dollar by 173.5% (1.3 vs 0.5), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, GeForce 8400M GT is the easier value choice. If you care more about 1080p and some 1440p headroom, RADEON X700 has the stronger long-term case.
