Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX Titan Black will be 367% faster than the Radeon R9 M365X overall, due to its higher bandwidth. (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 quite a bit (more or less 477%) more effective at 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 a high screen resolution is important to you, then the GeForce GTX Titan Black is the winner, and very much so. (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
