Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan X		250 Watts
Radeon R9 290X		300 Watts
	Difference: 50 Watts (20%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X will be 54% faster than the Radeon R9 290X in general, because of its higher data rate. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R9 290X		320000 MB/sec
	Difference: 171520 (54%)

Texel Rate

The Nvidia Titan X will be much (approximately 125%) more effective at texture filtering than the Radeon R9 290X. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R9 290X		140800 Mtexels/sec
	Difference: 176608 (125%)

Pixel Rate

The Nvidia Titan X should be quite a bit (more or less 166%) faster with regards to FSAA than the Radeon R9 290X, and also will be capable of handling higher screen resolutions better. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R9 290X		51200 Mpixels/sec
	Difference: 84832 (166%)

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 data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once 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 are applied in one second. This figure is worked out 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
