GeForce 8800 GTS (G80) 320MB vs GeForce 9600 GT 1GB

Intro

The GeForce 8800 GTS (G80) 320MB has a GPU clock speed of 513 MHz, and the 320 MB of GDDR3 RAM runs at 792 MHz through a 320-bit bus. It also is made up of 96 Stream Processors, 48 Texture Address Units, and 20 Raster Operation Units.

Compare those specs to the GeForce 9600 GT 1GB, which has a core clock speed of 650 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit bus, and makes use of a 65/55 nm design. It is comprised of 64 SPUs, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
