Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 580 3GB		244 Watts
GeForce GTX Titan X		250 Watts
	Difference: 6 Watts (2%)

Memory Bandwidth

In theory, the GeForce GTX Titan X will be 75% quicker than the GeForce GTX 580 3GB overall, because of its higher bandwidth. (explain)

GeForce GTX Titan X		336000 MB/sec
GeForce GTX 580 3GB		192384 MB/sec
	Difference: 143616 (75%)

Texel Rate

The GeForce GTX Titan X should be quite a bit (approximately 289%) more effective at anisotropic filtering than the GeForce GTX 580 3GB. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 142592 (289%)

Pixel Rate

The GeForce GTX Titan X is quite a bit (more or less 159%) better at AA than the GeForce GTX 580 3GB, and also capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 58944 (159%)

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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many 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.
