Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 560 Ti 448 should theoretically be quite a bit superior to the Radeon R9 M375X in general. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 72000 (100%)

Texel Rate

The GeForce GTX 560 Ti 448 is a small bit (approximately 1%) faster with regards to AF than the Radeon R9 M375X. (explain)

GeForce GTX 560 Ti 448		40992 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 392 (1%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 560 Ti 448 is the winner, and very much so. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 13040 (80%)

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 information (measured in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number 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 clock speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. 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 quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
