The GeForce GTX 965M will be quite a bit (more or less 140%) better at texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 35216 (140%)

Pixel Rate

The GeForce GTX 965M is a lot (approximately 170%) faster with regards to full screen anti-aliasing than the Radeon HD 5750 1GB, and capable of handling higher resolutions more effectively. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 19008 (170%)

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 data (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
