Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon HD 4850 1GB
IntroThe GeForce 8800 GT 512MB uses a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this specific card. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 4850 1GB, which has GPU core speed of 625 MHz, and 1024 MB of GDDR4 RAM running at 993 MHz through a 256-bit bus. It also is made up of 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4850 1GB should perform a small bit faster than the GeForce 8800 GT 512MB in general. (explain)
Texel RateThe GeForce 8800 GT 512MB should be much (about 34%) better at AF than the Radeon HD 4850 1GB. (explain)
Pixel RateThe Radeon HD 4850 1GB is a small bit (approximately 4%) better at AA than the GeForce 8800 GT 512MB, and also should be capable of handling higher resolutions more effectively. (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 max amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
