Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon HD 5570
IntroThe Radeon HD 3470 512MB features clock speeds of 800 MHz on the GPU, and 950 MHz on the 512 MB of GDDR3 RAM. It features 40(8x5) SPUs as well as 4 TAUs and 4 Rasterization Operator Units.Compare all of that to the Radeon HD 5570, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 RAM runs at a frequency of 900 MHz on this specific card. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3470 512MB, in theory, should perform just a bit faster than the Radeon HD 5570 overall. (explain)
Texel RateThe Radeon HD 5570 should be a lot (more or less 306%) better at AF than the Radeon HD 3470 512MB. (explain)
Pixel RateThe Radeon HD 5570 should be quite a bit (about 63%) faster with regards to FSAA than the Radeon HD 3470 512MB, and also will be able to handle higher resolutions better. (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 transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
