Compare any two graphics cards:
GeForce 9400 GT 256MB vs GeForce 9500 GT DDR2
IntroThe GeForce 9400 GT 256MB features a core clock frequency of 550 MHz and a GDDR2 memory frequency of 400 MHz. It also uses a 128-bit bus, and uses a 65 nm design. It is made up of 16 SPUs, 8 Texture Address Units, and 4 ROPs.Compare that to the GeForce 9500 GT DDR2, which comes with GPU core speed of 550 MHz, and 256 MB of DDR2 memory running at 500 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthAs far as performance goes, the GeForce 9500 GT DDR2 should in theory be quite a bit superior to the GeForce 9400 GT 256MB in general. (explain)
Texel RateThe GeForce 9500 GT DDR2 will be quite a bit (about 100%) more effective at AF than the GeForce 9400 GT 256MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 9500 GT DDR2 is superior to the GeForce 9400 GT 256MB, and very much so. (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 transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
