Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 970M should be 500% faster than the Radeon R7 M260 overall, due to its higher bandwidth. (explain)

GeForce GTX 970M		96000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 80000 (500%)

Texel Rate

The GeForce GTX 970M should be a lot (more or less 331%) faster with regards to AF than the Radeon R7 M260. (explain)

GeForce GTX 970M		73920 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 56760 (331%)

Pixel Rate

The GeForce GTX 970M will be quite a bit (about 675%) faster with regards to full screen anti-aliasing than the Radeon R7 M260, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 38632 (675%)

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 data (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
