Radeon HD 3470 512MB vs Radeon HD 6570 (OEM) 2GB
Intro
The Radeon HD 3470 512MB comes with a GPU core speed of 800 MHz, and the 512 MB of GDDR3 memory runs 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 that to the Radeon HD 6570 (OEM) 2GB, which has a core clock frequency of 650 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It is made up of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it 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, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core clock 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 processed in one second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
