Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 1GB should in theory be quite a bit faster than the Radeon R9 M375X overall. (explain)

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

Texel Rate

The Radeon R9 M375X is just a bit (more or less 7%) more effective at texture 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

The GeForce GTX 460 1GB should be a lot (about 33%) faster with regards to FSAA than the Radeon R9 M375X, and also able to handle higher screen resolutions more effectively. (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 largest amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
