GeForce 8800 GT 1GB vs Radeon HD 6750 1GB
Intro
The GeForce 8800 GT 1GB features a core clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit memory bus, and uses a 65 nm design. It is made up of 112 SPUs, 56 TAUs, and 16 ROPs.Compare those specifications to the Radeon HD 6750 1GB, which features a GPU core clock speed of 725 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also features 720 SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
