About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

GeForce GTX 880M vs T400 4GB: 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 880M

2014

Why buy it

  • ✅300% more VRAM for high-resolution textures and newer games (8 GB vs 2 GB).
  • ✅Measures 1mm instead of 156mm, a 155mm shorter card that is more SFF-friendly.

Trade-offs

  • ❌2014 hardware with 8 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 23.9 G3D/$ (Unknown MSRP vs $159 MSRP).
  • ❌306.7% higher power demand at 122W vs 30W.

T400 4GB

2021

Why buy it

  • ✅Delivers 100+% more G3D Mark for each dollar spent, at 23.9 vs 0 G3D/$ ($159 MSRP vs Unknown MSRP).
  • ✅GeForce GTX 880M is already obsolete for modern gaming, so T400 4GB is the less risky modern option long term.
  • ✅Draws 30W instead of 122W, a 92W reduction.

Trade-offs

  • ❌Less VRAM, with 2 GB vs 8 GB for high-resolution textures and newer games.
  • ❌Older hardware, 2 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
  • ❌15500% longer card at 156mm vs 1mm.

Quick Answers

Which GPU is faster for gaming right now?
GeForce GTX 880M is the faster gaming card right now based on the synthetic data we have. It leads by 0.6% in PassMark G3D (3,826 vs 3,803), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
T400 4GB is the safer long-term pick for 2026 and beyond. The case is simple: a 12nm process instead of 28nm and a newer 2021 generation instead of 2014. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
T400 4GB makes the most sense today based on the pricing and value data we have for this matchup. GeForce GTX 880M still makes more sense if max raw gaming performance matters more than value.
