Theoretically speaking, the GeForce GTX 950M is 5% quicker than the Radeon HD 3470 512MB in general, due to its higher bandwidth. (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 AF 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

The GeForce GTX 950M should be much (approximately 357%) more effective at anti-aliasing than the Radeon HD 3470 512MB, and also will be able to handle higher resolutions better. (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 information (measured in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends 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.
