Compare any two graphics cards:
GeForce 8800 GT 256MB vs Radeon HD 3850 1GB
IntroThe GeForce 8800 GT 256MB has a GPU core speed of 600 MHz, and the 256 MB of GDDR3 memory runs at 700 MHz through a 256-bit bus. It also is comprised of 112 SPUs, 56 TAUs, and 16 ROPs.Compare that to the Radeon HD 3850 1GB, which has GPU clock speed of 668 MHz, and 1024 MB of GDDR3 memory set to run at 828 MHz through a 256-bit bus. It also is comprised of 320(64x5) Stream Processors, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 3850 1GB is 18% quicker than the GeForce 8800 GT 256MB overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce 8800 GT 256MB will be quite a bit (about 214%) more effective at texture filtering than the Radeon HD 3850 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 3850 1GB is superior to the GeForce 8800 GT 256MB, though not 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It 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 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
