Radeon R7 370 2G		110 Watts
	Difference: 10 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 370 2G should be 17% quicker than the Radeon R9 M290X in general, due to its higher bandwidth. (explain)

Radeon R7 370 2G		179200 MB/sec
Radeon R9 M290X		153600 MB/sec
	Difference: 25600 (17%)

Texel Rate

The Radeon R9 M290X is a small bit (approximately 9%) more effective at AF than the Radeon R7 370 2G. (explain)

Radeon R9 M290X		68000 Mtexels/sec
Radeon R7 370 2G		62400 Mtexels/sec
	Difference: 5600 (9%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 370 2G is the winner, but only just. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon R9 M290X		27200 Mpixels/sec
	Difference: 4000 (15%)

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 past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
