Compare any two graphics cards:
VS

GeForce 8600 GTS vs GeForce GT 430 (OEM)

Intro

The GeForce 8600 GTS has core clock 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 ROPs.

Compare those specs to the GeForce GT 430 (OEM), which uses a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 RAM works at a speed of 900 MHz on this particular card. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.

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

Texel Rate

The GeForce GT 430 (OEM) is a small bit (more or less 4%) faster with regards to AF than the GeForce 8600 GTS. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8600 GTS is the winner, by far. (explain)

GeForce 8600 GTS 5400 Mpixels/sec
GeForce GT 430 (OEM) 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 information (counted in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core 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 one second.

Pixel Rate: Pixel rate is the most pixels the graphics 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 ROPs by the clock 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
