Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 560 Ti is 34% quicker than the Radeon R9 M380 overall, because of its higher bandwidth. (explain)

GeForce GTX 560 Ti		128256 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 32256 (34%)

Texel Rate

The GeForce GTX 560 Ti is a lot (approximately 32%) faster with regards to AF than the Radeon R9 M380. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 12608 (32%)

Pixel Rate

The GeForce GTX 560 Ti should be much (more or less 64%) more effective at anti-aliasing than the Radeon R9 M380, and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 10304 (64%)

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 largest amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
