GeForce 8400M GT vs RADEON X800 XL: 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 $299 less on MSRP ($50 MSRP vs $349 MSRP).
✅Delivers 577.8% more G3D Mark for each dollar spent, at 1.3 vs 0.2 G3D/$ ($50 MSRP vs $349 MSRP).
✅Draws 33W instead of 300W, a 267W reduction.

Trade-offs

❌Lower average FPS than RADEON X800 XL 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 X800 XL

2020

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 X800 XL 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.
❌
598% HIGHER MSRP
$349 MSRPvs$50 MSRP
❌Lower G3D Mark per dollar, at 0.2 vs 1.3 G3D/$ ($349 MSRP vs $50 MSRP).
❌809.1% higher power demand at 300W vs 33W.

Quick Answers

Which GPU is faster for gaming right now?

RADEON X800 XL 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 3% in PassMark G3D (69 vs 67), so the answer here is pretty clean.

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

RADEON X800 XL 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, 72 vs 0 ray-tracing units, and a newer 2020 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 $299 cheaper on MSRP at $50 vs $349, and it leads G3D-per-dollar by 577.8% (1.3 vs 0.2), 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 X800 XL has the stronger long-term case.
