Compare any two graphics cards:
GeForce 9400 GT 256MB vs GeForce 9500 GT DDR2
IntroThe GeForce 9400 GT 256MB uses a 65 nm design. nVidia has set the core speed at 550 MHz. The GDDR2 memory runs at a frequency of 400 MHz on this specific card. It features 16 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.Compare those specifications to the GeForce 9500 GT DDR2, which uses a 65 nm design. nVidia has set the core frequency at 550 MHz. The DDR2 RAM runs at a frequency of 500 MHz on this model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthIn theory, the GeForce 9500 GT DDR2 is 25% faster than the GeForce 9400 GT 256MB in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce 9500 GT DDR2 will be quite a bit (approximately 100%) better at AF than the GeForce 9400 GT 256MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 9500 GT DDR2 is a better choice, 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 maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one 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 - 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
