Radeon HD 5570 vs Radeon HD 6450 (OEM) 1GB
Intro
The Radeon HD 5570 comes with a core clock speed of 650 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 400(80x5) SPUs, 20 Texture Address Units, and 8 ROPs.Compare those specifications 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 memory is set to run at a speed of 900 MHz on this particular model. It features 160 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 applied in one second. This number is calculated by multiplying the total texture units 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 in a second.
Pixel Rate: Pixel rate is the most pixels the video card 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
