Compare any two graphics cards:
GeForce 9600 GT 1GB vs Radeon HD 3870 X2 512MB
IntroThe GeForce 9600 GT 1GB has a core clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit bus, and makes use of a 65/55 nm design. It features 64 SPUs, 32 TAUs, and 16 ROPs.Compare those specifications to the Radeon HD 3870 X2 512MB, which makes use of a 55 nm design. AMD has set the core speed at 825 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this specific card. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 3870 X2 512MB should be quite a bit faster than the GeForce 9600 GT 1GB in general. (explain)
Texel RateThe Radeon HD 3870 X2 512MB is a lot (about 27%) more effective at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 3870 X2 512MB is the winner, 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
