GeForce 8800 GTS (G92) vs Radeon HD 6750 1GB

Intro

The GeForce 8800 GTS (G92) makes use of a 65 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM is set to run at a speed of 970 MHz on this specific model. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon HD 6750 1GB, which makes use of a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this card. It features 720 SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
