Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs Radeon HD 6770
IntroThe GeForce GTX 560 Ti 448 features a GPU clock speed of 732 MHz, and the 1280 MB of GDDR5 memory runs at 900 MHz through a 320-bit bus. It also is comprised of 448 SPUs, 56 TAUs, and 40 Raster Operation Units.Compare those specifications to the Radeon HD 6770, which features GPU clock speed of 900 MHz, and 512 MB of GDDR5 memory running at 1050 MHz through a 128-bit bus. It also is comprised of 800 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 560 Ti 448 should in theory be much better than the Radeon HD 6770 overall. (explain)
Texel RateThe GeForce GTX 560 Ti 448 is a little bit (more or less 14%) faster with regards to AF than the Radeon HD 6770. (explain)
Pixel RateThe GeForce GTX 560 Ti 448 is much (approximately 103%) better at anti-aliasing than the Radeon HD 6770, 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: Bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
