Compare any two graphics cards:
GeForce 9600 GSO 512MB vs Radeon HD 3870 512MB
IntroThe GeForce 9600 GSO 512MB makes use of a 65/55 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 96 SPUs along with 48 Texture Address Units and 16 ROPs.Compare that to the Radeon HD 3870 512MB, which makes use of a 55 nm design. AMD has set the core frequency at 775 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this specific card. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)
Texel RateThe GeForce 9600 GSO 512MB is a lot (more or less 152%) more effective at AF than the Radeon HD 3870 512MB. (explain)
Pixel RateThe Radeon HD 3870 512MB is a little bit (about 19%) better at FSAA than the GeForce 9600 GSO 512MB, and should be capable of handling higher screen resolutions without slowing down too much. (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 MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
