Texel Rate

The GeForce GTX 880M will be quite a bit (approximately 23%) faster with regards to anisotropic filtering than the GeForce GTX 980M. (explain)

GeForce GTX 880M 122112 Mtexels/sec
GeForce GTX 980M 99648 Mtexels/sec
Difference: 22464 (23%)

Pixel Rate

The GeForce GTX 980M will be a lot (more or less 118%) faster with regards to FSAA than the GeForce GTX 880M, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 980M 66432 Mpixels/sec
GeForce GTX 880M 30528 Mpixels/sec
Difference: 35904 (118%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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