Compare any two graphics cards:
GeForce 8800 GT 1GB vs Radeon HD 3850 1GB
IntroThe GeForce 8800 GT 1GB has a core clock frequency of 600 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit bus, and uses a 65 nm design. It is comprised of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 3850 1GB, which uses a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 memory is set to run at a frequency of 828 MHz on this model. It features 320(64x5) SPUs as well as 16 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 8800 GT 1GB should theoretically be a little bit faster than the Radeon HD 3850 1GB in general. (explain)
Texel RateThe GeForce 8800 GT 1GB should be a lot (approximately 214%) faster with regards to AF than the Radeon HD 3850 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 3850 1GB is a better choice, but it probably won't make a huge difference. (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 data (counted in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
