Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 965M, in theory, should perform much faster than the Radeon HD 3470 512MB overall. (explain)

GeForce GTX 965M		64000 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 33600 (111%)

Texel Rate

The GeForce GTX 965M should be a lot (approximately 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

If using lots of anti-aliasing is important to you, then the GeForce GTX 965M is superior to the Radeon HD 3470 512MB, and very much so. (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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many 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.
