Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 7950 should be 233% quicker than the Radeon R9 M375X overall, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon HD 7950 should be a lot (approximately 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 running with lots of anti-aliasing is important to you, then the Radeon HD 7950 is the winner, and very much so. (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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
