Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 750 should theoretically be just a bit faster than the Radeon R9 M375X in general. (explain)

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

Texel Rate

The Radeon R9 M375X will be a lot (about 24%) more effective at texture 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 little bit (more or less 0%) more effective at full screen anti-aliasing than the Radeon R9 M375X, and will be 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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
