Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M270X should in theory be just a bit superior to the GeForce GTX 960M in general. (explain)

Radeon R9 M270X		72000 MB/sec
GeForce GTX 960M		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The GeForce GTX 960M should be a lot (more or less 51%) faster with regards to anisotropic filtering than the Radeon R9 M270X. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 14840 (51%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 960M is superior to the Radeon R9 M270X, by far. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 5936 (51%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
