Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 3850 1GB
IntroThe GeForce GT 440 3GB has a GPU core clock speed of 594 MHz, and the 3072 MB of GDDR3 RAM runs at 900 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 Texture Address Units, and 24 ROPs.Compare those specs to the Radeon HD 3850 1GB, which features a GPU core clock speed of 668 MHz, and 1024 MB of GDDR3 RAM running at 828 MHz through a 256-bit bus. It also is made up of 320(64x5) Stream Processors, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 3850 1GB should theoretically be quite a bit better than the GeForce GT 440 3GB overall. (explain)
Texel RateThe GeForce GT 440 3GB is quite a bit (about 33%) faster with regards to AF than the Radeon HD 3850 1GB. (explain)
Pixel RateThe GeForce GT 440 3GB will be a lot (more or less 33%) better at FSAA 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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
