Compare any two graphics cards:
Radeon HD 3470 256MB vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 3470 256MB comes with a core clock speed of 800 MHz and a DDR2 memory speed of 950 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 40(8x5) SPUs, 4 Texture Address Units, and 4 ROPs.Compare all that to the Radeon HD 6570 (OEM) 2GB, which comes with a core clock frequency of 650 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 6570 (OEM) 2GB should in theory be a lot better than the Radeon HD 3470 256MB overall. (explain)
Texel RateThe Radeon HD 6570 (OEM) 2GB will be much (approximately 388%) better at AF than the Radeon HD 3470 256MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6570 (OEM) 2GB 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 information (in units of MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
