Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon HD 5830
IntroThe Radeon HD 3470 512MB comes with a GPU core speed of 800 MHz, and the 512 MB of GDDR3 memory is set to run at 950 MHz through a 128-bit bus. It also is made up of 40(8x5) Stream Processors, 4 Texture Address Units, and 4 Raster Operation Units.Compare those specifications to the Radeon HD 5830, which comes with clock speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 5830 should in theory be much faster than the Radeon HD 3470 512MB in general. (explain)
Texel RateThe Radeon HD 5830 will be quite a bit (about 1300%) more effective at texture filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateThe Radeon HD 5830 will be a lot (more or less 300%) faster with regards to full screen anti-aliasing than the Radeon HD 3470 512MB, and also able to handle higher resolutions while still performing well. (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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 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 anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
