Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 950M should in theory be a little bit better than the Radeon HD 3470 512MB in general. (explain)

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

Texel Rate

The GeForce GTX 950M will be a lot (about 1043%) better at texture 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 950M is the winner, 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 largest amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
