The GeForce GTX 965M will be much (more or less 1788%) better at anisotropic filtering than the Radeon HD 3470 512MB. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 57216 (1788%)

Pixel Rate

The GeForce GTX 965M will be a lot (about 844%) more effective at AA than the Radeon HD 3470 512MB, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 27008 (844%)

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 data (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
