GeForce 8800 GT 1GB vs Radeon HD 3850 256MB
Intro
The GeForce 8800 GT 1GB features a clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit memory bus, and uses a 65 nm design. It is made up of 112 SPUs, 56 TAUs, and 16 ROPs.Compare those specs to the Radeon HD 3850 256MB, which comes with GPU clock speed of 668 MHz, and 256 MB of GDDR3 RAM set to run at 828 MHz through a 256-bit bus. It also features 320(64x5) SPUs, 16 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
