GeForce GTX 680M KY_Bullet Edition
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.
- ❌Lower G3D Mark per dollar, at 0 vs 20.1 G3D/$ (Unknown MSRP vs $180 MSRP).
- ❌306.7% higher power demand at 122W vs 30W.
T400
2021Why buy it
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 20.1 vs 0 G3D/$ ($180 MSRP vs Unknown MSRP).
- ✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
- ✅GeForce GTX 680M KY_Bullet Edition is already obsolete for modern gaming, so T400 is the less risky modern option long term.
- ✅Draws 30W instead of 122W, a 92W reduction.
Trade-offs
- ❌Older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
