Compare any two graphics cards:
GeForce 8400 GS 512MB vs GeForce GT 210
IntroThe GeForce 8400 GS 512MB makes use of a 80 nm design. nVidia has clocked the core speed at 650 MHz. The DDR2 RAM is set to run at a frequency of 400 MHz on this specific model. It features 16 SPUs as well as 8 Texture Address Units and 4 ROPs.
Compare those specifications to the GeForce GT 210, which comes with GPU core speed of 589 MHz, and 512 MB of DDR3 RAM set to run at 800 MHz through a 64-bit bus. It also features 16 SPUs, 8 TAUs, and 4 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GT 210 should in theory be a lot superior to the GeForce 8400 GS 512MB in general. (explain)
Texel RateThe GeForce 8400 GS 512MB will be just a bit (more or less 10%) better at AF than the GeForce GT 210. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 8400 GS 512MB is superior to the GeForce GT 210, not by a very large margin though. (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 information (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount 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 per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
