Compare any two graphics cards:
GeForce 8800 Ultra vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce 8800 Ultra features a GPU clock speed of 612 MHz, and the 768 MB of GDDR3 RAM is set to run at 1080 MHz through a 384-bit bus. It also features 128 SPUs, 64 TAUs, and 24 ROPs.Compare those specifications to the Radeon HD 6570 (OEM) 1GB, which has a clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 8800 Ultra will be 260% quicker than the Radeon HD 6570 (OEM) 1GB in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce 8800 Ultra is quite a bit (more or less 151%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 8800 Ultra is the winner, and very much so. (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 (measured in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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.
