GeForce GTX 870M vs T400: 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 GTX 870M
2014Why buy it
- ✅50% more VRAM for high-resolution textures and newer games (6 GB vs 4 GB).
Trade-offs
- ❌2014 hardware with 6 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌Lower G3D Mark per dollar, at 0 vs 20.1 G3D/$ (Unknown MSRP vs $180 MSRP).
- ❌233.3% higher power demand at 100W vs 30W.
T400
2021Why buy it
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 20.1 vs 0 G3D/$ ($180 MSRP vs Unknown MSRP).
- ✅GeForce GTX 870M is already obsolete for modern gaming, so T400 is the less risky modern option long term.
- ✅Draws 30W instead of 100W, a 70W reduction.
Trade-offs
- ❌Less VRAM, with 4 GB vs 6 GB for high-resolution textures and newer games.
- ❌Older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
