Trade-offs
- ❌2018 hardware with 2 GB of VRAM already sits in legacy territory for modern games.
- ❌6.9% HIGHER MSRP$170 MSRPvs$159 MSRP
- ❌Lower G3D Mark per dollar, at 21.8 vs 23.9 G3D/$ ($170 MSRP vs $159 MSRP).
- ❌33.3% higher power demand at 40W vs 30W.
T400 4GB
2021Why buy it
- ✅Costs $11 less on MSRP ($159 MSRP vs $170 MSRP).
- ✅Delivers 10% more G3D Mark for each dollar spent, at 23.9 vs 21.8 G3D/$ ($159 MSRP vs $170 MSRP).
- ✅Quadro P620 is already legacy-tier future-proofing, so T400 4GB is the less risky modern option long term.
- ✅Draws 30W instead of 40W, a 10W reduction.
Trade-offs
- ❌Older hardware, 2 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
