Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce GT 320
IntroThe GeForce 9500 GT 512MB GDDR3 features core speeds of 550 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 RAM. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare those specs to the GeForce GT 320, which comes with a clock frequency of 540 MHz and a GDDR3 memory speed of 790 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 72 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9500 GT 512MB GDDR3 should theoretically perform a bit faster than the GeForce GT 320 in general. (explain)
Texel RateThe GeForce GT 320 will be a lot (approximately 47%) better at AF than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateThe GeForce 9500 GT 512MB GDDR3 is a bit (more or less 2%) faster with regards to full screen anti-aliasing than the GeForce GT 320, and also will be capable of handling higher screen resolutions better. (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 data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
