The GeForce GTX 980M is quite a bit (about 289%) faster with regards to texture filtering than the Radeon HD 7750. (explain)

GeForce GTX 980M		99648 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 74048 (289%)

Pixel Rate

The GeForce GTX 980M will be much (more or less 419%) more effective at FSAA than the Radeon HD 7750, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 980M		66432 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 53632 (419%)

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 max amount of information (measured in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 can be processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
