Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 3470 512MB comes with a core clock frequency of 800 MHz and a GDDR3 memory frequency of 950 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It is made up of 40(8x5) SPUs, 4 Texture Address Units, and 4 Raster Operation Units.Compare those specs to the Radeon HD 6570 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this specific card. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3470 512MB should in theory be a small bit faster than the Radeon HD 6570 (OEM) 1GB overall. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB is a lot (approximately 388%) better at AF than the Radeon HD 3470 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6570 (OEM) 1GB 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 data (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are 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 higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
