Compare any two graphics cards:
GeForce GTX 660 vs Geforce GTX 760
IntroThe GeForce GTX 660 comes with a GPU clock speed of 980 MHz, and the 2048 MB of GDDR5 memory is set to run at 1502 MHz through a 192-bit bus. It also features 960 SPUs, 80 Texture Address Units, and 24 ROPs.
Compare all that to the Geforce GTX 760, which makes use of a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this specific model. It features 1152 SPUs along with 96 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Geforce GTX 760 is 33% faster than the GeForce GTX 660 overall, because of its greater bandwidth. (explain)
Texel RateThe Geforce GTX 760 is a bit (about 20%) more effective at texture filtering than the GeForce GTX 660. (explain)
Pixel RateThe Geforce GTX 760 is much (approximately 33%) faster with regards to full screen anti-aliasing than the GeForce GTX 660, and capable of handling higher resolutions better. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
