Radeon HD 5570 vs Radeon HD 6570 (OEM) 1GB
Intro
The Radeon HD 5570 uses a 40 nm design. AMD has clocked the core speed at 650 MHz. The DDR3 RAM is set to run at a frequency of 900 MHz on this card. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 ROPs.Compare those specs to the Radeon HD 6570 (OEM) 1GB, which comes with a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 ROPs.

Pixel Rate
Both cards have exactly the same pixel rate, so theoretically they should perform equally good at at anti-aliasing, and be capable of handling the same screen resolutions. (explain)Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core 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 processed per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
