Texel Rate

The GeForce GTX 960 will be quite a bit (more or less 1122%) better at texture filtering than the GeForce 810M. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 66224 (1122%)

Pixel Rate

The GeForce GTX 960 will be much (approximately 1122%) faster with regards to anti-aliasing than the GeForce 810M, and able to handle higher resolutions while still performing well. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 33112 (1122%)

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 (measured in MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
