Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce GT 320
IntroThe GeForce 9500 GT 512MB GDDR3 makes use of a 55 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 memory runs at a frequency of 800 MHz on this particular model. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the GeForce GT 320, which comes with core clock speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 RAM. It features 72 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9500 GT 512MB GDDR3 should theoretically be a bit faster than the GeForce GT 320 overall. (explain)
Texel RateThe GeForce GT 320 will be much (about 47%) better at AF than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateThe GeForce 9500 GT 512MB GDDR3 will be a small bit (about 2%) better at AA than the GeForce GT 320, and also should be capable of handling 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 MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
