Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce 9600 GSO 1.5GB
IntroThe GeForce 8600 GT 512MB DDR2 features a GPU core clock speed of 540 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 Texture Address Units, and 8 ROPs.Compare those specs to the GeForce 9600 GSO 1.5GB, which uses a 65 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 RAM runs at a frequency of 800 MHz on this particular card. It features 96 SPUs along with 48 TAUs and 12 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 9600 GSO 1.5GB should theoretically be quite a bit superior to the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce 9600 GSO 1.5GB is a lot (more or less 206%) better at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 9600 GSO 1.5GB is a better choice, by a large margin. (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 (in units of MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
