Geforce GTX 1080 Ti		250 Watts
	Difference: 140 Watts (127%)

Memory Bandwidth

As far as performance goes, the Geforce GTX 1080 Ti should theoretically be much superior to the GeForce GTX 650 Ti 2GB in general. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 409216 (474%)

Texel Rate

The Geforce GTX 1080 Ti should be quite a bit (more or less 458%) faster with regards to texture filtering than the GeForce GTX 650 Ti 2GB. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 272128 (458%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 1080 Ti is superior to the GeForce GTX 650 Ti 2GB, by far. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 115392 (777%)

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 information (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed 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 better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
