Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
GeForce GTX Titan		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan should be 10% quicker than the Radeon RX 590 overall, due to its greater bandwidth. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 26240 (10%)

Texel Rate

The Radeon RX 590 is just a bit (approximately 13%) faster with regards to texture filtering than the GeForce GTX Titan. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX Titan		187488 Mtexels/sec
	Difference: 24048 (13%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 590 is the winner, not by a very large margin though. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 6832 (17%)

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 maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock 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 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 maximum fill rate.
