Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 7950
IntroThe GeForce GTX 660 Ti features a GPU core speed of 915 MHz, and the 2048 MB of GDDR5 RAM runs at 1500 MHz through a 192-bit bus. It also features 1344 SPUs, 112 TAUs, and 24 Raster Operation Units.Compare all of that to the Radeon HD 7950, which features a core clock frequency of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 384-bit bus, and uses a 28 nm design. It features 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 7950 should perform a lot faster than the GeForce GTX 660 Ti in general. (explain)
Texel RateThe GeForce GTX 660 Ti is a bit (more or less 14%) more effective at anisotropic filtering than the Radeon HD 7950. (explain)
Pixel RateThe Radeon HD 7950 is a bit (approximately 17%) more effective at full screen anti-aliasing than the GeForce GTX 660 Ti, and also will be able to handle higher resolutions more effectively. (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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
