	Difference: 20 Watts (67%)

Memory Bandwidth

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

Texel Rate

The Radeon HD 6570 (OEM) 1GB should be a little bit (about 7%) faster with regards to texture filtering than the Radeon R7 240. (explain)

Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 1000 (7%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 240 is the winner, but it probably won't make a huge difference. (explain)

Radeon R7 240		5840 Mpixels/sec
Radeon HD 6570 (OEM) 1GB		5200 Mpixels/sec
	Difference: 640 (12%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
