Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 3850 512MB
IntroThe GeForce GT 440 1.5GB has a GPU clock speed of 594 MHz, and the 1536 MB of GDDR3 memory is set to run at 900 MHz through a 192-bit bus. It also features 144 Stream Processors, 24 TAUs, and 24 Raster Operation Units.Compare those specs to the Radeon HD 3850 512MB, which comes with core speeds of 668 MHz on the GPU, and 828 MHz on the 512 MB of GDDR3 memory. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 3850 512MB will be 23% faster than the GeForce GT 440 1.5GB overall, because of its greater data rate. (explain)
Texel RateThe GeForce GT 440 1.5GB should be quite a bit (about 33%) better at texture filtering than the Radeon HD 3850 512MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GT 440 1.5GB is the winner, 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
