GeForce GTX 950M		55 Watts
Radeon HD 5830		175 Watts
	Difference: 120 Watts (218%)

Memory Bandwidth

In theory, the Radeon HD 5830 will be 300% quicker than the GeForce GTX 950M in general, because of its greater data rate. (explain)

Radeon HD 5830		128000 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 96000 (300%)

Texel Rate

The Radeon HD 5830 will be much (more or less 23%) faster with regards to anisotropic filtering than the GeForce GTX 950M. (explain)

Radeon HD 5830		44800 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 8240 (23%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 950M is superior to the Radeon HD 5830, though not by far. (explain)

GeForce GTX 950M		14624 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 1824 (14%)

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 (in units of megabytes per second) that can be transported across 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 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
