Theoretically speaking, the Radeon HD 5750 1GB should be 15% faster than the GeForce GTX 965M overall, because of its greater data rate. (explain)

Radeon HD 5750 1GB		73600 MB/sec
GeForce GTX 965M		64000 MB/sec
	Difference: 9600 (15%)

Texel Rate

The GeForce GTX 965M should be quite a bit (more or less 140%) faster with regards to 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

If running with a high resolution is important to you, then the GeForce GTX 965M is a better choice, by far. (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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
