Compare any two graphics cards:
Radeon HD 3850 512MB vs Radeon HD 4730
IntroThe Radeon HD 3850 512MB comes with a GPU clock speed of 668 MHz, and the 512 MB of GDDR3 RAM runs at 828 MHz through a 256-bit bus. It also features 320(64x5) SPUs, 16 TAUs, and 16 ROPs.Compare those specifications to the Radeon HD 4730, which comes with a core clock speed of 700 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It features 640(128x5) SPUs, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4730 will be 9% faster than the Radeon HD 3850 512MB in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 4730 will be a lot (about 110%) faster with regards to texture filtering than the Radeon HD 3850 512MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 3850 512MB is the winner, 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 largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
