Compare any two graphics cards:
GeForce 8400 GS 512MB vs GeForce GT 210
IntroThe GeForce 8400 GS 512MB features a GPU core speed of 650 MHz, and the 512 MB of DDR2 RAM is set to run at 400 MHz through a 64-bit bus. It also is made up of 16 Stream Processors, 8 TAUs, and 4 ROPs.
Compare all of that to the GeForce GT 210, which uses a 40 nm design. nVidia has clocked the core speed at 589 MHz. The DDR3 memory is set to run at a speed of 800 MHz on this card. It features 16 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GT 210 should in theory be a lot better than the GeForce 8400 GS 512MB in general. (explain)
Texel RateThe GeForce 8400 GS 512MB should be a little bit (approximately 10%) faster with regards to texture filtering than the GeForce GT 210. (explain)
Pixel RateThe GeForce 8400 GS 512MB will be just a bit (more or less 10%) better at full screen anti-aliasing than the GeForce GT 210, and also should be able to handle higher screen resolutions more effectively. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core 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 is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
