Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 270 is 409% faster than the Radeon R9 M375 in general, because of its higher data rate. (explain)

Radeon R9 270		179200 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 144000 (409%)

Texel Rate

The Radeon R9 270 is a lot (more or less 77%) faster with regards to AF than the Radeon R9 M375. (explain)

Radeon R9 270		72000 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 31400 (77%)

Pixel Rate

The Radeon R9 270 will be much (about 77%) better at full screen anti-aliasing than the Radeon R9 M375, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon R9 270		28800 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 12560 (77%)

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 largest amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses 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 is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
