Radeon HD 5570 vs Radeon HD 6450 (OEM) 1GB
Intro
The Radeon HD 5570 comes with a clock speed of 650 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 400(80x5) SPUs, 20 TAUs, and 8 ROPs.Compare those specs to the Radeon HD 6450 (OEM) 1GB, which uses a 40 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM runs at a frequency of 900 MHz on this particular card. It features 160 SPUs as well as 8 Texture Address Units and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
