Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 660 Ti should in theory be much faster than the Radeon R9 M365X in general. (explain)

GeForce GTX 660 Ti		144000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 72000 (100%)

Texel Rate

The GeForce GTX 660 Ti should be much (about 177%) more effective at anisotropic filtering than the Radeon R9 M365X. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 65480 (177%)

Pixel Rate

The GeForce GTX 660 Ti is quite a bit (more or less 48%) faster with regards to anti-aliasing than the Radeon R9 M365X, and will be capable of handling higher screen resolutions better. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 7160 (48%)

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 largest amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 texture map elements (texels) that can be processed per second. This is calculated 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
