Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 950M should in theory be a little bit superior to the Radeon HD 3470 512MB overall. (explain)

GeForce GTX 950M		32000 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 1600 (5%)

Texel Rate

The GeForce GTX 950M is a lot (about 1043%) better at anisotropic filtering than the Radeon HD 3470 512MB. (explain)

GeForce GTX 950M		36560 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 33360 (1043%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 950M is superior to the Radeon HD 3470 512MB, and very much so. (explain)

GeForce GTX 950M		14624 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 11424 (357%)

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 information (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount 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 the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
