NVIDIA GeForce GTX 660 technical specs and benchmarks

Summary

NVIDIA started GeForce GTX 660 sales 6 September 2012 at a recommended price of 229 USD. This is a 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). An additional One 6-pin power connector is required, and power consumption is at 140 Watt.

It provides poor gaming and benchmark performance at 21.34 percent of a leader's which is NVIDIA TITAN Xp.

Technical specs

Quantitative parameters such as shaders number, GPU core clock, manufacturing process, texturing and calculation speed. These parameters indirectly say of video card performance, but to be more precise you have to review it's benchmark and gaming test results.

Compatibility, dimensions and requirements

Information on video card compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus - if the video card is inserted into the slot instead of being soldered to the notebook motherboard.
