Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 6950 should theoretically be quite a bit better than the Radeon R9 M365X overall. (explain)

Radeon HD 6950		160000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 88000 (122%)

Texel Rate

The Radeon HD 6950 is much (about 90%) faster with regards to anisotropic filtering than the Radeon R9 M365X. (explain)

Radeon HD 6950		70400 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 33400 (90%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6950 is superior to the Radeon R9 M365X, by a large margin. (explain)

Radeon HD 6950		25600 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 10800 (73%)

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 (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's 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 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock 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 amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
