GeForce 8600 GTS vs GeForce GT 430

Intro

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

Compare all that to the GeForce GT 430, which features a core clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 60 Watts
GeForce 8600 GTS 75 Watts
Difference: 15 Watts (25%)

Memory Bandwidth

The GeForce 8600 GTS, in theory, should perform a bit faster than the GeForce GT 430 in general. (explain)

GeForce 8600 GTS 32000 MB/sec
GeForce GT 430 28800 MB/sec
Difference: 3200 (11%)

Texel Rate

The GeForce GT 430 will be just a bit (more or less 4%) more effective at AF than the GeForce 8600 GTS. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 8600 GTS is a better choice, by a large margin. (explain)

GeForce 8600 GTS 5400 Mpixels/sec
GeForce GT 430 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 largest amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
