Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 560 Ti 448 is 309% faster than the Radeon R9 M375 overall, because of its greater data rate. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 108800 (309%)

Texel Rate

The GeForce GTX 560 Ti 448 is a bit (about 1%) more effective at anisotropic filtering than the Radeon R9 M375. (explain)

GeForce GTX 560 Ti 448		40992 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 392 (1%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 Ti 448 is the winner, by a large margin. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon R9 M375		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 max amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 in one second. This figure is worked out 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
