Compare any two graphics cards:
GeForce 8800 GS vs GeForce GT 210
IntroThe GeForce 8800 GS comes with core 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 features a core clock speed of 589 MHz and a DDR3 memory frequency of 800 MHz. It also features a 64-bit bus, and uses a 40 nm design. It is made up of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce 8800 GS should theoretically perform quite a bit faster than the GeForce GT 210 in general. (explain)
Texel RateThe GeForce 8800 GS should be a lot (more or less 460%) better at texture filtering than the GeForce GT 210. (explain)
Pixel RateThe GeForce 8800 GS will be quite a bit (approximately 180%) better at full screen anti-aliasing than the GeForce GT 210, and also will be able to handle higher resolutions better. (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 data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
