Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 560 should in theory be much superior to the Radeon R9 M375X in general. (explain)

GeForce GTX 560		128128 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 56128 (78%)

Texel Rate

The GeForce GTX 560 is a bit (more or less 12%) faster with regards to texture filtering than the Radeon R9 M375X. (explain)

GeForce GTX 560		45360 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 4760 (12%)

Pixel Rate

The GeForce GTX 560 will be a lot (more or less 60%) more effective at FSAA than the Radeon R9 M375X, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 9680 (60%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If 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 number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
