Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 6750 1GB
IntroThe GeForce GTX 660 Ti features a core clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 192-bit memory bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 Texture Address Units, and 24 ROPs.
Compare all of that to the Radeon HD 6750 1GB, which has a core clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 720 SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 660 Ti is 125% faster than the Radeon HD 6750 1GB overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 660 Ti should be quite a bit (about 293%) faster with regards to AF than the Radeon HD 6750 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 660 Ti is the winner, by a large margin. (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 maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
