Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 560 Ti 448 should in theory be a lot better than 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 will be a bit (approximately 1%) faster with regards to texture filtering 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti 448 is superior to the Radeon R9 M375X, 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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
