Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 is 20% faster than the Radeon R9 M375X in general, due to its greater data rate. (explain)

GeForce GTX 460		86400 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The Radeon R9 M375X will be a little bit (more or less 7%) faster with regards to texture filtering than the GeForce GTX 460. (explain)

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

Pixel Rate

The Radeon R9 M375X will be just a bit (approximately 0%) better at full screen anti-aliasing than the GeForce GTX 460, and will be capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 40 (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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
