Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 6770 1GB
IntroThe GeForce GT 440 1.5GB features a GPU core clock speed of 594 MHz, and the 1536 MB of GDDR3 RAM is set to run at 900 MHz through a 192-bit bus. It also features 144 SPUs, 24 TAUs, and 24 ROPs.Compare that to the Radeon HD 6770 1GB, which makes use of a 40 nm design. AMD has set the core speed at 900 MHz. The GDDR5 memory works at a speed of 1050 MHz on this specific model. It features 800 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 6770 1GB should perform much faster than the GeForce GT 440 1.5GB in general. (explain)
Texel RateThe Radeon HD 6770 1GB should be quite a bit (approximately 153%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6770 1GB is superior to the GeForce GT 440 1.5GB, but only just. (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 information (in units of MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
