Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 980 Ti should be 367% faster than the Radeon R9 M375X in general, due to its greater bandwidth. (explain)

GeForce GTX 980 Ti		336000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 264000 (367%)

Texel Rate

The GeForce GTX 980 Ti should be much (about 333%) faster with regards to anisotropic filtering than the Radeon R9 M375X. (explain)

GeForce GTX 980 Ti		176000 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 135400 (333%)

Pixel Rate

The GeForce GTX 980 Ti should be quite a bit (more or less 491%) better at FSAA than the Radeon R9 M375X, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 79760 (491%)

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 information (in units of MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
