GeForce 8600 GT 512MB DDR2 vs Radeon HD 5750 512MB

Intro

The GeForce 8600 GT 512MB DDR2 comes with a core clock frequency of 540 MHz and a DDR2 memory frequency of 400 MHz. It also features a 128-bit bus, and makes use of a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the Radeon HD 5750 512MB, which has core clock speeds of 700 MHz on the GPU, and 1150 MHz on the 512 MB of GDDR5 RAM. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 maximum fill rate.
