Compare any two graphics cards:
GeForce 8400 GS 512MB vs GeForce GT 210
IntroThe GeForce 8400 GS 512MB comes with a core clock speed of 650 MHz and a DDR2 memory speed of 400 MHz. It also uses a 64-bit bus, and makes use of a 80 nm design. It features 16 SPUs, 8 TAUs, and 4 Raster Operation Units.
Compare all of that to the GeForce GT 210, which comes with a clock speed of 589 MHz and a DDR3 memory speed of 800 MHz. It also makes use of a 64-bit bus, and makes use of a 40 nm design. It features 16 SPUs, 8 TAUs, and 4 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GT 210 should theoretically be much better than the GeForce 8400 GS 512MB overall. (explain)
Texel RateThe GeForce 8400 GS 512MB is a small bit (more or less 10%) faster with regards to texture filtering than the GeForce GT 210. (explain)
Pixel RateThe GeForce 8400 GS 512MB will be a small bit (more or less 10%) faster with regards to anti-aliasing than the GeForce GT 210, and also able to handle higher screen 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 maximum amount of information (measured in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
