The Turing architecture in both GPUs bring faster processing than their Pascal predecessors and Nvidia says they're more power efficient as well.

Like its desktop version, the 1660 Ti sounds like a compelling performance sweet spot -- Nvidia claims 100-plus frames per second at 1080p for the most popular competitive games (like, you know, Fortnite), which leaves some room for it to deliver reasonable performance on more graphically intensive games at 1080p.
