Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 6770
IntroThe GeForce GT 340 1GB has a core clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It features 96 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the Radeon HD 6770, which comes with a core clock speed of 900 MHz and a GDDR5 memory speed of 1050 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is made up of 800 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6770, in theory, should be much faster than the GeForce GT 340 1GB in general. (explain)
Texel RateThe Radeon HD 6770 will be a lot (about 105%) faster with regards to texture filtering than the GeForce GT 340 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6770 is a better choice, and very much so. (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 max amount of data (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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.
