Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 470 should in theory be much faster than the Radeon R9 M375X overall. (explain)

GeForce GTX 470		133920 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 61920 (86%)

Texel Rate

The Radeon R9 M375X will be a little bit (approximately 19%) better at anisotropic filtering than the GeForce GTX 470. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 6608 (19%)

Pixel Rate

The GeForce GTX 470 is quite a bit (approximately 50%) better at AA than the Radeon R9 M375X, and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 470		24280 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 8040 (50%)

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 moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
