See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
GRID K520
2013Why buy it
- ✅Competitive enough if your priority is price, power, or specific feature preference.
Trade-offs
- ❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
- ❌2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌1899.4% HIGHER MSRP$3,599 MSRPvs$180 MSRP
- ❌Lower G3D Mark per dollar, at 1.0 vs 20.1 G3D/$ ($3,599 MSRP vs $180 MSRP).
- ❌650% higher power demand at 225W vs 30W.
T400
2021Why buy it
- ✅Costs $3,419 less on MSRP ($180 MSRP vs $3,599 MSRP).
- ✅Delivers 1952.3% more G3D Mark for each dollar spent, at 20.1 vs 1.0 G3D/$ ($180 MSRP vs $3,599 MSRP).
- ✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
- ✅GRID K520 is already obsolete for modern gaming, so T400 is the less risky modern option long term.
- ✅Draws 30W instead of 225W, a 195W reduction.
Trade-offs
- ❌Older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
