Compare any two graphics cards:
GeForce 8800 GS vs GeForce GT 210
IntroThe GeForce 8800 GS makes use of a 65 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 memory is set to run at a speed of 800 MHz on this particular card. It features 96 SPUs along with 48 Texture Address Units and 12 Rasterization Operator Units.
Compare that to the GeForce GT 210, which features core speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce 8800 GS should perform a lot faster than the GeForce GT 210 in general. (explain)
Texel RateThe GeForce 8800 GS will be quite a bit (more or less 460%) more effective at texture filtering than the GeForce GT 210. (explain)
Pixel RateThe GeForce 8800 GS should be quite a bit (about 180%) better at anti-aliasing than the GeForce GT 210, and also will be capable of handling 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum 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 clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
