GeForce 8400 SE vs RADEON X600 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
2014Why buy it
- ✅Costs $49 less on MSRP ($50 MSRP vs $99 MSRP).
- ✅Delivers 101% more G3D Mark for each dollar spent, at 1.4 vs 0.7 G3D/$ ($50 MSRP vs $99 MSRP).
- ✅Draws 33W instead of 150W, a 117W reduction.
- ✅Measures 168mm instead of 170mm, a 2mm shorter card that is more SFF-friendly.
Trade-offs
- ❌Lower average FPS than RADEON X600 PRO across 50 tracked games in our benchmark data.
- ❌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 X600 PRO
2020Why buy it
- ✅2.0% more average FPS across 50 tracked games in our benchmark data.
- ✅GeForce 8400 SE is already obsolete for modern gaming, so RADEON X600 PRO is the less risky modern option long term.
- ✅More future proof: RDNA 1.0 (2019−2020) on 7nm with a newer platform for upcoming games.
Trade-offs
- ❌Older hardware, 512 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
- ❌98% HIGHER MSRP$99 MSRPvs$50 MSRP
- ❌Lower G3D Mark per dollar, at 0.7 vs 1.4 G3D/$ ($99 MSRP vs $50 MSRP).
- ❌354.5% higher power demand at 150W vs 33W.
