Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should be 100% quicker than the GeForce GTX 950M overall, due to its higher bandwidth. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 32000 (100%)

Texel Rate

The GeForce GTX 950M should be a lot (about 85%) more effective at texture filtering than the Radeon R7 M260X. (explain)

GeForce GTX 950M		36560 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 16760 (85%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 950M is superior to the Radeon R7 M260X, by far. (explain)

GeForce GTX 950M		14624 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 8024 (122%)

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 max amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
