Compare any two graphics cards:
GeForce 9600 GT 512MB vs GeForce 9800 GT 1GB
IntroThe GeForce 9600 GT 512MB comes with a core clock speed of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit memory bus, and uses a 65/55 nm design. It is made up of 64 SPUs, 32 TAUs, and 16 ROPs.Compare that to the GeForce 9800 GT 1GB, which uses a 65/55 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory works at a frequency of 900 MHz on this specific card. It features 112 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same memory bandwidth, so theoretically they should have the same performance. (explain)
Texel RateThe GeForce 9800 GT 1GB will be much (approximately 62%) more effective at AF than the GeForce 9600 GT 512MB. (explain)
Pixel RateThe GeForce 9600 GT 512MB should be a bit (about 8%) faster with regards to anti-aliasing than the GeForce 9800 GT 1GB, and also 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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units 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 applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
