Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs GeForce GT 440 3GB
IntroThe GeForce 8600 GT 1GB GDDR3 has a core clock frequency of 540 MHz and a GDDR3 memory speed of 700 MHz. It also makes use of a 128-bit memory bus, and makes use of a 80 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the GeForce GT 440 3GB, which uses a 40 nm design. nVidia has clocked the core speed at 594 MHz. The GDDR3 memory works at a frequency of 900 MHz on this card. It features 144 SPUs as well as 24 Texture Address Units and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 440 3GB, in theory, should be quite a bit faster than the GeForce 8600 GT 1GB GDDR3 overall. (explain)
Texel RateThe GeForce GT 440 3GB should be much (about 65%) better at texture filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateThe GeForce GT 440 3GB is quite a bit (approximately 230%) better at anti-aliasing than the GeForce 8600 GT 1GB GDDR3, and able to handle higher resolutions without losing too much performance. (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 max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, 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 maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. 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 output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
