Compare any two graphics cards:
Radeon HD 4730 vs Radeon HD 6770 1GB
IntroThe Radeon HD 4730 has a GPU core speed of 700 MHz, and the 512 MB of GDDR5 memory runs at 900 MHz through a 128-bit bus. It also is made up of 640(128x5) Stream Processors, 32 TAUs, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 6770 1GB, which has core clock speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 memory. It features 800 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6770 1GB is 17% faster than the Radeon HD 4730 overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 6770 1GB should be quite a bit (approximately 61%) more effective at texture filtering than the Radeon HD 4730. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6770 1GB is superior to the Radeon HD 4730, by far. (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 information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
