Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 4850 1GB
IntroThe GeForce GT 440 3GB comes with a GPU core speed of 594 MHz, and the 3072 MB of GDDR3 memory runs at 900 MHz through a 192-bit bus. It also is made up of 144 SPUs, 24 Texture Address Units, and 24 ROPs.Compare all of that to the Radeon HD 4850 1GB, which comes with a GPU core clock speed of 625 MHz, and 1024 MB of GDDR4 RAM running at 993 MHz through a 256-bit bus. It also features 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4850 1GB, in theory, should be quite a bit faster than the GeForce GT 440 3GB in general. (explain)
Texel RateThe Radeon HD 4850 1GB will be a lot (approximately 75%) faster with regards to texture filtering than the GeForce GT 440 3GB. (explain)
Pixel RateThe GeForce GT 440 3GB should be a lot (approximately 43%) faster with regards to FSAA than the Radeon HD 4850 1GB, and also should be able to handle higher screen 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 (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
