Compare any two graphics cards:
GeForce 9600 GT 512MB vs Radeon HD 3870 1GB
IntroThe GeForce 9600 GT 512MB has core speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 64 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the Radeon HD 3870 1GB, which has a clock speed of 775 MHz and a GDDR4 memory speed of 1125 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It is made up of 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 3870 1GB is 25% faster than the GeForce 9600 GT 512MB in general, due to its higher data rate. (explain)
Texel RateThe GeForce 9600 GT 512MB will be much (approximately 68%) more effective at anisotropic filtering than the Radeon HD 3870 1GB. (explain)
Pixel RateThe Radeon HD 3870 1GB will be a little bit (more or less 19%) better at full screen anti-aliasing than the GeForce 9600 GT 512MB, and capable of handling higher resolutions while still performing well. (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 maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a 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 - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
