Compare any two graphics cards:
Radeon HD 3470 256MB vs Radeon HD 5570
IntroThe Radeon HD 3470 256MB comes with a GPU clock speed of 800 MHz, and the 256 MB of DDR2 memory is set to run at 950 MHz through a 128-bit bus. It also is made up of 40(8x5) SPUs, 4 TAUs, and 4 Raster Operation Units.Compare those specs to the Radeon HD 5570, which has a core clock frequency of 650 MHz and a DDR3 memory frequency of 900 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is comprised of 400(80x5) SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3470 256MB should theoretically perform a bit faster than the Radeon HD 5570 overall. (explain)
Texel RateThe Radeon HD 5570 will be quite a bit (about 306%) more effective at AF than the Radeon HD 3470 256MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 5570 is a better choice, 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: Bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If 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, HDR 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 texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
