The GeForce GTX 960M should be a lot (approximately 74%) better at texture filtering than the Radeon HD 5750 512MB. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 18640 (74%)

Pixel Rate

The GeForce GTX 960M is quite a bit (more or less 57%) better at FSAA than the Radeon HD 5750 512MB, and able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 6336 (57%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses 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 amount of texture map elements (texels) that can be processed 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 graphics 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 most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
