Compare any two graphics cards:
GeForce 9400 GT 256MB vs GeForce GT 210
IntroThe GeForce 9400 GT 256MB makes use of a 65 nm design. nVidia has set the core frequency at 550 MHz. The GDDR2 memory is set to run at a frequency of 400 MHz on this particular model. It features 16 SPUs as well as 8 TAUs and 4 ROPs.Compare those specs to the GeForce GT 210, which has a clock speed of 589 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 64-bit bus, and uses a 40 nm design. It is made up of 16 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so in theory they should have identical performance. (explain)
Texel RateThe GeForce GT 210 should be a bit (about 7%) more effective at AF than the GeForce 9400 GT 256MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GT 210 is a better choice, though not by far. (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 largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that are applied per second. This figure is worked out 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
