GeForce 8600 GTS vs GeForce GT 430 1GB

Intro

The GeForce 8600 GTS comes with clock speeds of 675 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 RAM. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare those specifications to the GeForce GT 430 1GB, which has GPU clock speed of 700 MHz, and 1024 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is made up of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

GeForce GT 430 1GB 28800 MB/sec
Difference: 3200 (11%)

Texel Rate

The GeForce GT 430 1GB will be just a bit (about 4%) better at texture filtering than the GeForce 8600 GTS. (explain)

GeForce GT 430 1GB 11200 Mtexels/sec
GeForce 8600 GTS 10800 Mtexels/sec
Difference: 400 (4%)

Pixel Rate

The GeForce 8600 GTS will be a lot (more or less 93%) better at FSAA than the GeForce GT 430 1GB, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce 8600 GTS 5400 Mpixels/sec
GeForce GT 430 1GB 2800 Mpixels/sec
Difference: 2600 (93%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the 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 number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
