Compare any two graphics cards:
GeForce 9400 GT 256MB vs GeForce 9600 GSO 384MB
IntroThe GeForce 9400 GT 256MB has a GPU clock speed of 550 MHz, and the 256 MB of GDDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is comprised of 16 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.Compare that to the GeForce 9600 GSO 384MB, which has a core clock frequency of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also features a 192-bit memory bus, and makes use of a 65 nm design. It is comprised of 96 SPUs, 48 TAUs, and 12 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9600 GSO 384MB should perform a lot faster than the GeForce 9400 GT 256MB overall. (explain)
Texel RateThe GeForce 9600 GSO 384MB will be quite a bit (more or less 500%) better at texture filtering than the GeForce 9400 GT 256MB. (explain)
Pixel RateThe GeForce 9600 GSO 384MB is a lot (approximately 200%) better at FSAA than the GeForce 9400 GT 256MB, and should be capable of handling higher 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 max amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
