Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 280		236 Watts
Geforce GTX 1080 Ti		250 Watts
	Difference: 14 Watts (6%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 1080 Ti should be 250% faster than the GeForce GTX 280 in general, due to its greater data rate. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
GeForce GTX 280		141696 MB/sec
	Difference: 353920 (250%)

Texel Rate

The Geforce GTX 1080 Ti should be a lot (approximately 588%) faster with regards to anisotropic filtering than the GeForce GTX 280. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
GeForce GTX 280		48160 Mtexels/sec
	Difference: 283360 (588%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 1080 Ti is a better choice, and very much so. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
GeForce GTX 280		19264 Mpixels/sec
	Difference: 110976 (576%)

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 information (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
