Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan Black should theoretically be a lot faster than the Radeon R9 M365X overall. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 264000 (367%)

Texel Rate

The GeForce GTX Titan Black will be much (about 477%) faster with regards to anisotropic filtering than the Radeon R9 M365X. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 176360 (477%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is a better choice, by a large margin. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 27872 (188%)

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: Bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
