Compare any two graphics cards:
GeForce 8800 GS vs GeForce GT 210
IntroThe GeForce 8800 GS comes with clock speeds of 550 MHz on the GPU, and 800 MHz on the 384 MB of GDDR3 memory. It features 96 SPUs along with 48 Texture Address Units and 12 Rasterization Operator Units.
Compare those specifications to the GeForce GT 210, which comes with clock speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 16 SPUs along with 8 Texture Address Units and 4 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce 8800 GS will be 200% quicker than the GeForce GT 210 in general, because of its higher data rate. (explain)
Texel RateThe GeForce 8800 GS is much (more or less 460%) faster with regards to texture filtering than the GeForce GT 210. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 8800 GS is a better choice, by far. (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 largest amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
