Compare any two graphics cards:
GeForce GTX 660 Ti vs Geforce GTX 670
IntroThe GeForce GTX 660 Ti makes use of a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this model. It features 1344 SPUs along with 112 Texture Address Units and 24 ROPs.
Compare that to the Geforce GTX 670, which features a clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 670 will be 33% faster than the GeForce GTX 660 Ti overall, because of its greater data rate. (explain)
Texel RateBoth cards have the exact same texel rate, so theoretically they should be equally good at at AF. (explain)
Pixel RateThe Geforce GTX 670 should be a lot (about 33%) better at FSAA than the GeForce GTX 660 Ti, and should be able to handle 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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
