GeForce 8800 GTX vs GeForce 9800 GTX

Intro

The GeForce 8800 GTX features a core clock speed of 575 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 384-bit memory bus, and uses a 90 nm design. It is made up of 128 SPUs, 64 TAUs, and 24 Raster Operation Units.

Compare those specifications to the GeForce 9800 GTX, which features a GPU core clock speed of 675 MHz, and 512 MB of GDDR3 memory set to run at 1100 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
