Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs GeForce GT 430
IntroThe GeForce 8600 GT 512MB GDDR3 has clock speeds of 540 MHz on the GPU, and 700 MHz on the 512 MB of GDDR3 RAM. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.Compare all that to the GeForce GT 430, which uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular card. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 430 should in theory perform quite a bit faster than the GeForce 8600 GT 512MB GDDR3 overall. (explain)
Texel RateThe GeForce GT 430 is much (approximately 30%) better at AF than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateThe GeForce 8600 GT 512MB GDDR3 will be quite a bit (more or less 54%) faster with regards to AA than the GeForce GT 430, and also should be capable of handling higher screen resolutions more effectively. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
