Compare any two graphics cards:
GeForce 9600 GSO 512MB vs Radeon HD 6850
IntroThe GeForce 9600 GSO 512MB uses a 65/55 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this card. It features 96 SPUs as well as 48 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 6850, which features a core clock frequency of 775 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It features 960 SPUs, 48 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6850 should be 122% quicker than the GeForce 9600 GSO 512MB overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 6850 should be a small bit (about 19%) faster with regards to AF than the GeForce 9600 GSO 512MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6850 is superior to the GeForce 9600 GSO 512MB, by a large margin. (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 information (measured in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, 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 most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
