Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should be 100% faster than the GeForce GTS 150 in general, due to its greater bandwidth. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 32000 (100%)

Texel Rate

The GeForce GTS 150 will be much (about 139%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)

GeForce GTS 150		47360 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 27560 (139%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTS 150 is superior to the Radeon R7 M260X, by far. (explain)

GeForce GTS 150		11840 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 5240 (79%)

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 (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many 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.
