Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M290X should in theory perform much faster than the Radeon R9 M365X overall. (explain)

Radeon R9 M290X		153600 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 81600 (113%)

Texel Rate

The Radeon R9 M290X should be much (approximately 84%) more effective at texture filtering than the Radeon R9 M365X. (explain)

Radeon R9 M290X		68000 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 31000 (84%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M290X is a better choice, by far. (explain)

Radeon R9 M290X		27200 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 12400 (84%)

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 (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip 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 amount of Raster Operations Pipelines 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 is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
