Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 5570
IntroThe GeForce GT 440 3GB comes with core clock speeds of 594 MHz on the GPU, and 900 MHz on the 3072 MB of GDDR3 memory. It features 144 SPUs along with 24 TAUs and 24 ROPs.
Compare those specs to the Radeon HD 5570, which comes with GPU core speed of 650 MHz, and 512 MB of DDR3 memory set to run at 900 MHz through a 128-bit bus. It also features 400(80x5) SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GT 440 3GB is 50% quicker than the Radeon HD 5570 overall, because of its greater data rate. (explain)
Texel RateThe GeForce GT 440 3GB will be a bit (about 10%) faster with regards to anisotropic filtering than the Radeon HD 5570. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 440 3GB is superior to the Radeon HD 5570, and very much so. (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 information (counted in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
