Compare any two graphics cards:
GeForce 8800 GT 1GB vs Radeon HD 6770 1GB
IntroThe GeForce 8800 GT 1GB has a core clock speed of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit memory bus, and uses a 65 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 6770 1GB, which features a core clock speed of 900 MHz and a GDDR5 memory speed of 1050 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It features 800 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6770 1GB should theoretically be a small bit superior to the GeForce 8800 GT 1GB overall. (explain)
Texel RateThe Radeon HD 6770 1GB should be a small bit (about 7%) better at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6770 1GB is a better choice, 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 largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If 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 can be processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
