Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 550 Ti will be 37% quicker than the Radeon R9 M365X in general, because of its greater bandwidth. (explain)

GeForce GTX 550 Ti		98496 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 26496 (37%)

Texel Rate

The Radeon R9 M365X will be much (more or less 28%) more effective at AF than the GeForce GTX 550 Ti. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 8200 (28%)

Pixel Rate

The GeForce GTX 550 Ti will be much (about 46%) faster with regards to FSAA than the Radeon R9 M365X, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 6800 (46%)

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 maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that are 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 higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
