Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce 9500 GT 512MB GDDR3
IntroThe GeForce 8600 GT 256MB GDDR3 uses a 80 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 RAM works at a speed of 700 MHz on this model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specifications to the GeForce 9500 GT 512MB GDDR3, which comes with a clock frequency of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also makes use of a 128-bit bus, and uses a 55 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9500 GT 512MB GDDR3 should be a little bit faster than the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe GeForce 9500 GT 512MB GDDR3 should be a little bit (about 2%) more effective at anisotropic filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 9500 GT 512MB GDDR3 is superior to the GeForce 8600 GT 256MB GDDR3, not by a very large margin though. (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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the 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 higher the card's 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 applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 processed in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
