GeForce 8800 Ultra vs GeForce 9500 GT 1GB GDDR3

Intro

The GeForce 8800 Ultra has a GPU clock speed of 612 MHz, and the 768 MB of GDDR3 RAM is set to run at 1080 MHz through a 384-bit bus. It also features 128 SPUs, 64 TAUs, and 24 ROPs.

Compare those specs to the GeForce 9500 GT 1GB GDDR3, which features core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR3 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount 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 colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
