NVIDIA GeForce GTX 660 technical specs and benchmarks

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 22.67 percent of a leader's which is NVIDIA Quadro P6000.

Info on video card type (desktop or notebook), its architecture and sales start time and price.

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.

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.

Parameters of memory installed on the video card - type, size, bus, clock and resulting bandwidth. GPUs integrated into processors don't have dedicated memory and use a shared part of system RAM.

Video connectors present on the video card. Mostly actual for desktop video cards since notebook ones' available video connectors vastly depend on the notebook model.

Technological solutions supported by the GPU. You'll probably need this information if you require some particular technology.

APIs supported by video card, sometimes including their particular versions.

Non-gaming benchmarks performance. Overall benchmark performance is measured in points in 0-100 range.

Video card cryptocurrency mining capabilities. Usually measured in megahashes per second.

How good for gaming a particular GPU is. Gaming benchmark results are measured in FPS. Overall gaming performance is a number in 0-100 range, and the older the game, the less impact it has on the overall grade of the video card.
