Theoretically speaking, the Radeon HD 6970 will be 511% faster than the Radeon R7 240 in general, because of its greater data rate. (explain)

Radeon HD 6970		176000 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 147200 (511%)

Texel Rate

The Radeon HD 6970 is quite a bit (more or less 479%) better at AF than the Radeon R7 240. (explain)

Radeon HD 6970		84480 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 69880 (479%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6970 is a better choice, and very much so. (explain)

Radeon HD 6970		28160 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 22320 (382%)

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: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated 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 filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
