Radeon HD 5570 vs Radeon HD 6450 (OEM) 1GB
Intro
The Radeon HD 5570 makes use of a 40 nm design. AMD has set the core speed at 650 MHz. The DDR3 RAM works at a frequency of 900 MHz on this specific model. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.Compare all that to the Radeon HD 6450 (OEM) 1GB, which makes use of a 40 nm design. AMD has set the core speed at 750 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this specific model. It features 160 SPUs along with 8 TAUs and 4 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also 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 bandwidth is, the lower the ability to reach the maximum fill rate.
