GeForce 8600 GT 256MB GDDR3 vs GeForce GT 430 1GB

Intro

The GeForce 8600 GT 256MB GDDR3 uses a 80 nm design. nVidia has clocked the core speed at 540 MHz. The GDDR3 memory works at a speed of 700 MHz on this model. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare all of that to the GeForce GT 430 1GB, which features a core clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels 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 Raster Operations Pipelines by the the core 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
