Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 1GB is 60% quicker than the Radeon R9 M375X overall, due to its higher data rate. (explain)

GeForce GTX 460 1GB		115200 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 43200 (60%)

Texel Rate

The Radeon R9 M375X will be a bit (about 7%) more effective at anisotropic filtering than the GeForce GTX 460 1GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 2800 (7%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 1GB is the winner, by far. (explain)

GeForce GTX 460 1GB		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: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
