NVIDIA GeForce GTX 660: specs and benchmarks
Summary
NVIDIA started GeForce GTX 660 sales 6 September 2012 at a recommended price of $229. This is Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at gamers. 2 GB of GDDR5 memory clocked at 6.0 GB/s are supplied, and together with 192-bit GDDR5 memory interface this creates a bandwidth of 144.2 GB / s.
Compatibility-wise, this is 2-slot card attached via PCIe 3.0 x16 interface. Its manufacturer default version has a length of 9.5" (24.1 cm). one 6-pin power connector is required, and power consumption is at 140 Watt.
It provides poor gaming and benchmark performance at 21.46 percent of a leader's which is NVIDIA GeForce GTX 1080 SLI Mobile.
