Compare any two graphics cards:
Radeon HD 4730 vs Radeon HD 6770 1GB
IntroThe Radeon HD 4730 comes with a core clock frequency of 700 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It is comprised of 640(128x5) SPUs, 32 TAUs, and 8 Raster Operation Units.Compare those specs to the Radeon HD 6770 1GB, which comes with a clock frequency of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It features 800 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6770 1GB will be 17% faster than the Radeon HD 4730 overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 6770 1GB should be much (approximately 61%) faster with regards to AF than the Radeon HD 4730. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6770 1GB is superior to the Radeon HD 4730, by a large margin. (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 maximum amount of data (measured in megabytes 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 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, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
