Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X, in theory, should be a lot faster than the Radeon R7 M260 overall. (explain)

Radeon R9 M375X		72000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M375X should be quite a bit (approximately 137%) better at texture filtering than the Radeon R7 M260. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 23440 (137%)

Pixel Rate

The Radeon R9 M375X will be much (more or less 184%) more effective at AA than the Radeon R7 M260, and also capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 10520 (184%)

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 max amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
