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

Mobility Radeon HD 4270

2009

Why buy it

✅Costs $450 less on MSRP ($49 MSRP vs $499 MSRP).
✅Delivers 866.4% more G3D Mark for each dollar spent, at 1.9 vs 0.2 G3D/$ ($49 MSRP vs $499 MSRP).
✅100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).
✅Draws 30W instead of 300W, a 270W reduction.

Trade-offs

❌2009 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 XT

2020

Why buy it

✅Mobility Radeon HD 4270 is already obsolete for modern gaming, so RADEON X800 XT 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

❌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.
❌
918.4% HIGHER MSRP
$499 MSRPvs$49 MSRP
❌Lower G3D Mark per dollar, at 0.2 vs 1.9 G3D/$ ($499 MSRP vs $49 MSRP).
❌900% higher power demand at 300W vs 30W.

Quick Answers

Which GPU is faster for gaming right now?

RADEON X800 XT is the faster gaming card right now based on the synthetic data we have. It leads by 5.4% in PassMark G3D (98 vs 93), which is the best performance signal available in this matchup.

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

RADEON X800 XT is the safer long-term pick for 2026 and beyond. The case is simple: a 7nm process instead of 55nm, 72 vs 0 ray-tracing units, and a newer 2020 generation instead of 2009. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Mobility Radeon HD 4270 makes the most sense to buy today. It is $450 cheaper on MSRP at $49 vs $499, and it leads G3D-per-dollar by 866.4% (1.9 vs 0.2), which is enough to swing the recommendation its way.
