Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 480 4GB should be 219% quicker than the Radeon R9 M365X in general, due to its higher bandwidth. (explain)

Radeon RX 480 4GB		229376 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 480 4GB will be much (approximately 336%) better at texture filtering than the Radeon R9 M365X. (explain)

Radeon RX 480 4GB		161280 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 124280 (336%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 480 4GB is a better choice, and very much so. (explain)

Radeon RX 480 4GB		35840 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 21040 (142%)

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 (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of 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 calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
