GeForce 8400 SE vs RADEON X800 PRO: 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 8400 SE

2014

Why buy it

✅96.0% more average FPS across 50 tracked games in our benchmark data.
✅Costs $349 less on MSRP ($50 MSRP vs $399 MSRP).
✅Delivers 734.8% more G3D Mark for each dollar spent, at 1.4 vs 0.2 G3D/$ ($50 MSRP vs $399 MSRP).
✅100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).
✅Draws 33W instead of 250W, a 217W reduction.

Trade-offs

❌2014 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

RADEON X800 PRO

2020

Why buy it

✅GeForce 8400 SE is already obsolete for modern gaming, so RADEON X800 PRO 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

❌Lower average FPS than GeForce 8400 SE across 50 tracked games in our benchmark data.
❌Less VRAM, with 256 MB vs 512 MB for high-resolution textures and newer games.
❌Older hardware, 256 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌
698% HIGHER MSRP
$399 MSRPvs$50 MSRP
❌Lower G3D Mark per dollar, at 0.2 vs 1.4 G3D/$ ($399 MSRP vs $50 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

GeForce 8400 SE is the faster gaming card right now. In our data, it leads by 96.0% in average FPS across 50 tracked games in our benchmark data and by 4.6% in PassMark G3D (68 vs 65), so the answer here is pretty clean.

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

RADEON X800 PRO 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, 60 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 8400 SE makes the most sense to buy today. It is $349 cheaper on MSRP at $50 vs $399, and it leads G3D-per-dollar by 734.8% (1.4 vs 0.2), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, GeForce 8400 SE is the easier value choice. If you care more about 1080p and some 1440p headroom, RADEON X800 PRO has the stronger long-term case.
