NVIDIA GeForce GTX 660: specs and benchmarks

NVIDIA GeForce GTX 660

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 dual-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 15.19 percent of a leader's which is AMD Radeon RX 6900 XT.

Benchmark performance

Non-gaming benchmark performance of GeForce GTX 660. Note that overall benchmark performance is measured in points in 0-100 range.

Overall score

This is our combined benchmark performance rating. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.

3DMark Fire Strike Graphics

Fire Strike is a DirectX 11 benchmark for gaming PCs. It features two separate tests displaying a fight between a humanoid and a fiery creature seemingly made of lava. Using 1920x1080 resolution, Fire Strike shows off some realistic enough graphics and is quite taxing on hardware.

5040

Passmark

This is probably the most ubiquitous benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.

Octane Render OctaneBench

This is a special benchmark measuring graphics card performance in OctaneRender, which is a realistic GPU rendering engine by OTOY Inc., available either as a standalone program, or as a plugin for 3DS Max, Cinema 4D and many other apps. It renders four different static scenes, then compares render times with a reference GPU which is currently GeForce GTX 980. This benchmark has nothing to do with gaming and is aimed at professional 3D graphics artists.
