GeForce 8600 GTS vs GeForce GT 430 1GB

Intro

The GeForce 8600 GTS has core speeds of 675 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 RAM. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare those specifications to the GeForce GT 430 1GB, which makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

In theory, the GeForce 8600 GTS will be 11% faster than the GeForce GT 430 1GB overall, due to its higher data rate. (explain)

GeForce 8600 GTS 32000 MB/sec
GeForce GT 430 1GB 28800 MB/sec
Difference: 3200 (11%)

Texel Rate

The GeForce GT 430 1GB is just a bit (approximately 4%) faster with regards to AF 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 is much (approximately 93%) more effective at FSAA than the GeForce GT 430 1GB, and also able to handle higher screen 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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that are processed in one second. This 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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