Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 3850 1GB
IntroThe GeForce GT 440 1.5GB has a GPU core 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 is comprised of 144 Stream Processors, 24 TAUs, and 24 ROPs.Compare those specs to the Radeon HD 3850 1GB, which has core speeds of 668 MHz on the GPU, and 828 MHz on the 1024 MB of GDDR3 RAM. It features 320(64x5) SPUs as well as 16 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 3850 1GB should be much faster than the GeForce GT 440 1.5GB overall. (explain)
Texel RateThe GeForce GT 440 1.5GB is much (approximately 33%) faster with regards to anisotropic filtering than the Radeon HD 3850 1GB. (explain)
Pixel RateThe GeForce GT 440 1.5GB is quite a bit (more or less 33%) faster with regards to anti-aliasing than the Radeon HD 3850 1GB, and will be capable of handling higher resolutions while still performing well. (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 maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card 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 applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
