Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 460 2GB should in theory be much better than the Radeon R9 M375X overall. (explain)

GeForce GTX 460 2GB		115200 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 43200 (60%)

Texel Rate

The Radeon R9 M375X will be just a bit (more or less 7%) more effective at texture filtering than the GeForce GTX 460 2GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 2800 (7%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 2GB is the winner, by far. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 5360 (33%)

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 max amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If 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 applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
