GeForce 8800 GT 1GB vs GeForce GT 240 GDDR5 1GB

Intro

The GeForce 8800 GT 1GB makes use of a 65 nm design. nVidia has clocked the core frequency at 600 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this model. It features 112 SPUs as well as 56 Texture Address Units and 16 ROPs.

Compare those specs to the GeForce GT 240 GDDR5 1GB, which has a core clock speed of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is comprised of 96 SPUs, 32 TAUs, and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
