Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 290 should theoretically perform a lot faster than the Radeon R9 M365X in general. (explain)

Radeon R9 290		320000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 248000 (344%)

Texel Rate

The Radeon R9 290 is quite a bit (approximately 246%) more effective at AF than the Radeon R9 M365X. (explain)

Radeon R9 290		128000 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 91000 (246%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 290 is a better choice, by far. (explain)

Radeon R9 290		51200 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 36400 (246%)

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 data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can 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 Raster Operations Pipelines by the clock speed of the card. 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 of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
