Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 270 is 149% faster than the Radeon R9 M370X overall, due to its higher bandwidth. (explain)

Radeon R9 270		179200 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 107200 (149%)

Texel Rate

The Radeon R9 270 should be much (approximately 125%) more effective at anisotropic filtering than the Radeon R9 M370X. (explain)

Radeon R9 270		72000 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 40000 (125%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 270 is superior to the Radeon R9 M370X, by far. (explain)

Radeon R9 270		28800 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 16000 (125%)

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 data (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
