Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 970M should in theory perform quite a bit faster than the Radeon R9 M375 overall. (explain)

GeForce GTX 970M		96000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 60800 (173%)

Texel Rate

The GeForce GTX 970M should be quite a bit (approximately 82%) more effective at AF than the Radeon R9 M375. (explain)

GeForce GTX 970M		73920 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 33320 (82%)

Pixel Rate

The GeForce GTX 970M is quite a bit (approximately 173%) more effective at anti-aliasing than the Radeon R9 M375, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 28112 (173%)

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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, 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 most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
