Radeon HD 5570 vs Radeon HD 6970
Intro
The Radeon HD 5570 has a core clock frequency of 650 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 400(80x5) SPUs, 20 Texture Address Units, and 8 Raster Operation Units.Compare that to the Radeon HD 6970, which makes use of a 40 nm design. AMD has set the core frequency at 880 MHz. The GDDR5 RAM works at a speed of 1375 MHz on this model. It features 1536 SPUs along with 96 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
