Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce 9600 GT 512MB
IntroThe GeForce 9600 GT 1GB has a GPU clock speed of 650 MHz, and the 1024 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also is made up of 64 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the GeForce 9600 GT 512MB, which uses a 65/55 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular model. It features 64 SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)
Texel RateBoth cards have exactly the same texel fill rate, so in theory they should be equally good at at anisotropic filtering. (explain)Pixel RateBoth cards have exactly the same pixel fill rate, so in theory they should be equally good at at FSAA, and be capable of handling the same screen resolutions. (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 transported over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If 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 per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
