Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 550 Ti should theoretically be a little bit superior to the Radeon R9 M385X overall. (explain)

GeForce GTX 550 Ti		98496 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 2496 (3%)

Texel Rate

The Radeon R9 M385X will be quite a bit (more or less 114%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 32800 (114%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 550 Ti is a better choice, by far. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 4000 (23%)

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 (measured in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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