Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 750 should be 11% faster than the Radeon R9 M375X overall, due to its greater data rate. (explain)

GeForce GTX 750		80000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 8000 (11%)

Texel Rate

The Radeon R9 M375X is quite a bit (about 24%) faster with regards to anisotropic filtering than the GeForce GTX 750. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 7960 (24%)

Pixel Rate

The GeForce GTX 750 will be a bit (about 0%) more effective at FSAA than the Radeon R9 M375X, and also capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 750		16320 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 80 (0%)

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 (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 are applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
