Compare any two graphics cards:
VS

Radeon HD 5570 vs Radeon HD 6570 (OEM) 1GB

Intro

The Radeon HD 5570 makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this particular card. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the Radeon HD 6570 (OEM) 1GB, which has GPU clock speed of 650 MHz, and 1024 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also is comprised of 480 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570 43 Watts
Radeon HD 6570 (OEM) 1GB 50 Watts
Difference: 7 Watts (16%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The Radeon HD 6570 (OEM) 1GB is a bit (about 20%) better at anisotropic filtering than the Radeon HD 5570. (explain)

Radeon HD 6570 (OEM) 1GB 15600 Mtexels/sec
Radeon HD 5570 13000 Mtexels/sec
Difference: 2600 (20%)

Pixel Rate

Both cards have exactly the same pixel fill rate, so theoretically they should be equally good at at FSAA, 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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
