Compare any two graphics cards:
Radeon HD 4550 512MB vs Radeon HD 5830
IntroThe Radeon HD 4550 512MB comes with a GPU core clock speed of 600 MHz, and the 512 MB of GDDR3 RAM is set to run at 800 MHz through a 64-bit bus. It also is comprised of 80(16x5) SPUs, 8 TAUs, and 4 ROPs.Compare those specs to the Radeon HD 5830, which makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this particular model. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5830, in theory, should be a lot faster than the Radeon HD 4550 512MB in general. (explain)
Texel RateThe Radeon HD 5830 is a lot (about 833%) better at anisotropic filtering than the Radeon HD 4550 512MB. (explain)
Pixel RateThe Radeon HD 5830 is quite a bit (about 433%) faster with regards to anti-aliasing than the Radeon HD 4550 512MB, and will be able to handle higher resolutions more effectively. (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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock 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 processed per 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. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
