Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 3850 512MB
IntroThe GeForce GT 440 3GB uses a 40 nm design. nVidia has clocked the core speed at 594 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this card. It features 144 SPUs along with 24 TAUs and 24 Rasterization Operator Units.Compare those specs to the Radeon HD 3850 512MB, which comes with GPU clock speed of 668 MHz, and 512 MB of GDDR3 memory running at 828 MHz through a 256-bit bus. It also is made up of 320(64x5) Stream Processors, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 3850 512MB should be much faster than the GeForce GT 440 3GB in general. (explain)
Texel RateThe GeForce GT 440 3GB will be much (about 33%) better at AF than the Radeon HD 3850 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GT 440 3GB is a better choice, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
