Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 560 should theoretically be quite a bit superior to the Radeon R9 M380 overall. (explain)

GeForce GTX 560		128128 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 32128 (33%)

Texel Rate

The GeForce GTX 560 should be a bit (more or less 13%) more effective at anisotropic filtering than the Radeon R9 M380. (explain)

GeForce GTX 560		45360 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 5360 (13%)

Pixel Rate

The GeForce GTX 560 should be much (approximately 62%) faster with regards to FSAA than the Radeon R9 M380, and also should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 9920 (62%)

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 information (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
