Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce GT 430
IntroThe GeForce 8600 GT 256MB GDDR3 uses a 80 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 RAM runs at a speed of 700 MHz on this particular model. It features 32 SPUs along with 16 TAUs and 8 ROPs.Compare those specifications to the GeForce GT 430, which makes use of a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 memory works at a frequency of 900 MHz on this particular model. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 430 should theoretically be a lot superior to the GeForce 8600 GT 256MB GDDR3 in general. (explain)
Texel RateThe GeForce GT 430 will be quite a bit (more or less 30%) better at texture filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateThe GeForce 8600 GT 256MB GDDR3 is much (approximately 54%) faster with regards to full screen anti-aliasing than the GeForce GT 430, and also will be able to handle 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: Bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If 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 in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
