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

Intro

The Radeon HD 6570 (OEM) 2GB makes use of a 40 nm design. AMD has set the core frequency at 650 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular model. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Compare that to the Radeon HD 6750, which makes use of a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this particular card. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.

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 theoretically they should have the same performance. (explain)

Texel Rate

The Radeon HD 6750 is quite a bit (about 67%) faster with regards to AF 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

The Radeon HD 6750 is a lot (about 123%) better at anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and also will be able to handle higher screen resolutions without losing too much performance. (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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
