Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M365X should in theory be quite a bit better than the Radeon HD 4550 512MB overall. (explain)

Radeon R9 M365X		72000 MB/sec
Radeon HD 4550 512MB		12800 MB/sec
	Difference: 59200 (463%)

Texel Rate

The Radeon R9 M365X is quite a bit (approximately 671%) better at AF than the Radeon HD 4550 512MB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 4550 512MB		4800 Mtexels/sec
	Difference: 32200 (671%)

Pixel Rate

The Radeon R9 M365X should be a lot (about 517%) more effective at FSAA than the Radeon HD 4550 512MB, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 4550 512MB		2400 Mpixels/sec
	Difference: 12400 (517%)

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 max amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
