Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Geforce GTX 780 should in theory be a lot better than the Radeon R9 M375X overall. (explain)

Geforce GTX 780		288384 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 216384 (301%)

Texel Rate

The Geforce GTX 780 should be a lot (approximately 308%) more effective at texture filtering than the Radeon R9 M375X. (explain)

Geforce GTX 780		165696 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 125096 (308%)

Pixel Rate

If running with high levels of AA is important to you, then the Geforce GTX 780 is a better choice, by far. (explain)

Geforce GTX 780		41424 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 25184 (155%)

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 information (in units of megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
