Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 5850
IntroThe GeForce GTX 660 Ti features a GPU clock speed of 915 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1500 MHz through a 192-bit bus. It also is made up of 1344 SPUs, 112 Texture Address Units, and 24 ROPs.Compare those specifications to the Radeon HD 5850, which makes use of a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this specific model. It features 1440(288x5) SPUs along with 72 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 660 Ti should theoretically be a small bit superior to the Radeon HD 5850 overall. (explain)
Texel RateThe GeForce GTX 660 Ti is much (about 96%) better at texture filtering than the Radeon HD 5850. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 5850 is superior to the GeForce GTX 660 Ti, but not by far. (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 max amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once 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 AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be 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 the texel rate, the better the graphics card will be at handling 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 that the graphics chip can possibly write to the 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
