Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 370 4G		110 Watts
Radeon HD 6970		250 Watts
	Difference: 140 Watts (127%)

Memory Bandwidth

In theory, the Radeon R7 370 4G will be 2% quicker than the Radeon HD 6970 overall, because of its higher bandwidth. (explain)

Radeon R7 370 4G		179200 MB/sec
Radeon HD 6970		176000 MB/sec
	Difference: 3200 (2%)

Texel Rate

The Radeon HD 6970 should be a lot (approximately 35%) faster with regards to AF than the Radeon R7 370 4G. (explain)

Radeon HD 6970		84480 Mtexels/sec
Radeon R7 370 4G		62400 Mtexels/sec
	Difference: 22080 (35%)

Pixel Rate

The Radeon R7 370 4G should be just a bit (about 11%) better at anti-aliasing than the Radeon HD 6970, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
Radeon HD 6970		28160 Mpixels/sec
	Difference: 3040 (11%)

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 maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
