Compare any two graphics cards:
GeForce 8400 GS 512MB vs GeForce GT 210
IntroThe GeForce 8400 GS 512MB has a clock speed of 650 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 64-bit memory bus, and uses a 80 nm design. It features 16 SPUs, 8 TAUs, and 4 Raster Operation Units.
Compare those specs to the GeForce GT 210, which features a clock frequency of 589 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 64-bit bus, and makes use of a 40 nm design. It is comprised of 16 SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GT 210 should be a lot faster than the GeForce 8400 GS 512MB in general. (explain)
Texel RateThe GeForce 8400 GS 512MB is a bit (more or less 10%) faster with regards to AF than the GeForce GT 210. (explain)
Pixel RateThe GeForce 8400 GS 512MB is just a bit (approximately 10%) faster with regards to FSAA than the GeForce GT 210, and also should be capable of handling higher resolutions without slowing down too much. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core 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 applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
