Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 7950 should theoretically be quite a bit faster than the Radeon R9 M375X in general. (explain)

Radeon HD 7950		240000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 168000 (233%)

Texel Rate

The Radeon HD 7950 will be a lot (more or less 121%) faster with regards to anisotropic filtering than the Radeon R9 M375X. (explain)

Radeon HD 7950		89600 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 49000 (121%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 7950 is superior to the Radeon R9 M375X, by far. (explain)

Radeon HD 7950		25600 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 9360 (58%)

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 (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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