Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 4770
IntroThe GeForce GT 440 3GB comes with a core clock speed of 594 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 192-bit memory bus, and makes use of a 40 nm design. It is made up of 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.Compare those specs to the Radeon HD 4770, which uses a 40 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 RAM is set to run at a frequency of 800 MHz on this model. It features 640(128x5) SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4770 is 19% quicker than the GeForce GT 440 3GB in general, because of its higher data rate. (explain)
Texel RateThe Radeon HD 4770 is much (approximately 68%) faster with regards to texture filtering than the GeForce GT 440 3GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GT 440 3GB is superior to the Radeon HD 4770, 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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write 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 the core 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
