Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 760 are noticeably better than the Nvidia GeForce GTX 660.
The GeForce GTX 760 and the GeForce GTX 660 have the same core clock speed of 980 MHz, but the GeForce GTX 760 has 16 more Texture Mapping Units than the GeForce GTX 660. As a result, the GeForce GTX 760 exhibits a 15.7 GTexel/s better Texture Fill Rate than the GeForce GTX 660. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The GeForce GTX 760 and the GeForce GTX 660 have the same core clock speed of 980 MHz, but the GeForce GTX 760 has 8 more Render Output Units than the GeForce GTX 660. As a result, the GeForce GTX 760 exhibits a 7.9 GPixel/s better Pixel Fill Rate than the GeForce GTX 660. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The GeForce GTX 760 was released less than a year after the GeForce GTX 660, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GTX 760 and the GeForce GTX 660 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The GeForce GTX 760 has 48.1 GB/sec greater memory bandwidth than the GeForce GTX 660, which means that the memory performance of the GeForce GTX 760 is noticeably better than the GeForce GTX 660.
The GeForce GTX 760 has 1152 Shader Processing Units and the GeForce GTX 660 has 960. However, the actual shader performance of the GeForce GTX 760 is 1189 and the actual shader performance of the GeForce GTX 660 is 992. The GeForce GTX 760 having 197 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 760 delivers a significantly smoother and more efficient experience when processing graphical data than the GeForce GTX 660.
The GeForce GTX 760 requires 170 Watts to run and the GeForce GTX 660 requires 140 Watts. We would recommend a PSU with at least 500 Watts for the GeForce GTX 760 and a PSU with at least 450 Watts for the GeForce GTX 660. The GeForce GTX 760 requires 30 Watts more than the GeForce GTX 660 to run. The difference is not significant enough for the GeForce GTX 760 to have a noticeably larger impact on your yearly electricity bills than the GeForce GTX 660.
|Mini Review||GeForce GTX 760 is a mainstream Graphics Card based on the 28nm, Kepler architecture. |
It packs a Kepler GK104 Core and therefore offer 1152 Shader Processing Units, 96 TMUs and 32 ROPs on a 256-bit memory interface of fast GDDR5. While its central unit runs at 980MHz and goes up to 1032MHz, in Turbo Mode, the memory clock operates at 1502MHz. It draws up to 170W.
Benchmarks indicate its performance is superior to GeForce GTX 660 Ti and just a little beneath GeForce GTX 670.
Suited for a 1080p resolution, most modern games will run at the highest settings while extremely demanding games, such as Crysis 3 & Metro Last Light will require a more modest preset to be played optimally.
GeForce GTX 660 is a Performance Graphics Card based on the Kepler Architecture.
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.
It equips a GPU GK106-400-A1 which has 5 Stream Multiprocessors activated and thus offers 960 Shader Processing Units, 80 TMUs and 24 ROPs. The Central Unit is initially clocked at 980MHz and goes up to 1033MHz, in Turbo Mode.
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1502MHz.
With a rated board TDP of 140W, it requires at least a 450W PSU with one available 6-pin connector.
GeForce GTX 660 competes with Radeon HD 7850.
At 1920x1080, the best suited resolution for GeForce GTX 660, benchmarks indicate its performance is a little over the older GeForce GTX 570 and quite superior to Radeon HD 7850.
GeForce GTX 660 is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
