GeForce 930M		14400 MB/sec
	Difference: 209600 (1456%)

Texel Rate

The GeForce GTX 980 should be much (more or less 547%) more effective at AF than the GeForce 930M. (explain)

GeForce GTX 980		144128 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 121856 (547%)

Pixel Rate

The GeForce GTX 980 is quite a bit (approximately 871%) more effective at AA than the GeForce 930M, and also capable of handling higher resolutions more effectively. (explain)

GeForce GTX 980		72064 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 64640 (871%)

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 largest amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at 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 video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
