NVIDIA GeForce GTX 660M: specs and benchmarks

NVIDIA GeForce GTX 660M

Summary

NVIDIA started GeForce GTX 660M sales 22 March 2012. This is Kepler architecture notebook card based on 28 nm manufacturing process and primarily aimed at gamers. 1 GB of GDDR5 memory clocked at 2 GHz are supplied, and together with 128bit memory interface this creates a bandwidth of 64.0 GB / s.

Compatibility-wise, this is card attached via MXM-B (3.0) interface. Power consumption is at 50 Watt.

It provides poor gaming and benchmark performance at 7.48 percent of a leader's which is NVIDIA GeForce GTX 1080 SLI Mobile.
