Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 6770
IntroThe GeForce GTX 660 Ti features a GPU clock speed of 915 MHz, and the 2048 MB of GDDR5 memory is set to run at 1500 MHz through a 192-bit bus. It also features 1344 SPUs, 112 Texture Address Units, and 24 ROPs.Compare those specs to the Radeon HD 6770, which features GPU core speed of 900 MHz, and 512 MB of GDDR5 RAM set to run at 1050 MHz through a 128-bit bus. It also features 800 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 660 Ti should be quite a bit faster than the Radeon HD 6770 overall. (explain)
Texel RateThe GeForce GTX 660 Ti will be a lot (about 185%) better at anisotropic filtering than the Radeon HD 6770. (explain)
Pixel RateThe GeForce GTX 660 Ti will be much (about 53%) better at anti-aliasing than the Radeon HD 6770, and also will be able to handle higher screen resolutions while still performing well. (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 data (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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.
