Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 4770
IntroThe GeForce GT 440 1.5GB comes with clock speeds of 594 MHz on the GPU, and 900 MHz on the 1536 MB of GDDR3 RAM. It features 144 SPUs as well as 24 TAUs and 24 ROPs.Compare that to the Radeon HD 4770, which features a clock speed of 750 MHz and a GDDR5 memory frequency of 800 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 640(128x5) SPUs, 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 1.5GB in general, due to its greater bandwidth. (explain)
Texel RateThe Radeon HD 4770 should be a lot (about 68%) faster with regards to texture filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 440 1.5GB is superior to the Radeon HD 4770, not by a very large margin though. (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 data (counted in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, 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 number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
