GeForce GTX 1660 Ti (Mobile)
2020Why buy it
- ✅Draws 50W instead of 72W, a 22W reduction.
Trade-offs
- ❌Less VRAM, with 6 GB vs 8 GB for high-resolution textures and newer games.
- ❌Older hardware, 6 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
- ❌Lower G3D Mark per dollar, at 0 vs 4.3 G3D/$ (Unknown MSRP vs $2,345 MSRP).
L4
2023Why buy it
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 4.3 vs 0 G3D/$ ($2,345 MSRP vs Unknown MSRP).
- ✅33.3% more VRAM for high-resolution textures and newer games (8 GB vs 6 GB).
- ✅Better long-term bet: Ada Lovelace (2022−2024) on 5nm gives it a newer hardware base for upcoming games.
Trade-offs
- ❌44% higher power demand at 72W vs 50W.
