Radeon HD 6570 (OEM) 2GB vs Radeon HD 6750

Intro

The Radeon HD 6570 (OEM) 2GB features a GPU core speed of 650 MHz, and the 1024 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also features 480 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Compare those specs to the Radeon HD 6750, which features a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 720 SPUs, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6570 (OEM) 2GB 50 Watts
Radeon HD 6750 86 Watts
Difference: 36 Watts (72%)

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The Radeon HD 6750 is a lot (more or less 67%) better at anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

Radeon HD 6750 26100 Mtexels/sec
Radeon HD 6570 (OEM) 2GB 15600 Mtexels/sec
Difference: 10500 (67%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 6750 is the winner, and very much so. (explain)

Radeon HD 6750 11600 Mpixels/sec
Radeon HD 6570 (OEM) 2GB 5200 Mpixels/sec
Difference: 6400 (123%)

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 largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
