GeForce 8800 GT 512MB vs GeForce 9800 GTX+

Intro

The GeForce 8800 GT 512MB features a GPU clock speed of 600 MHz, and the 512 MB of GDDR3 memory runs at 900 MHz through a 256-bit bus. It also is made up of 112 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Compare those specifications to the GeForce 9800 GTX+, which comes with GPU core speed of 738 MHz, and 512 MB of GDDR3 memory running at 1100 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out 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 filling the screen with pixels (the image). 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.
