Texel Rate

The GeForce GTX 1080 will be quite a bit (approximately 5357%) more effective at anisotropic filtering than the GeForce GT 310. (explain)

GeForce GTX 1080		257120 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 252408 (5357%)

Pixel Rate

The GeForce GTX 1080 should be quite a bit (about 4265%) more effective at FSAA than the GeForce GT 310, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1080		102848 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 100492 (4265%)

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 data (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range 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 number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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