GeForce GTX 950M		55 Watts
GeForce GT 430 (OEM)		60 Watts
	Difference: 5 Watts (9%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950M will be 11% faster than the GeForce GT 430 (OEM) overall, due to its greater data rate. (explain)

GeForce GTX 950M		32000 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 3200 (11%)

Texel Rate

The GeForce GTX 950M should be much (more or less 226%) more effective at texture filtering than the GeForce GT 430 (OEM). (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 25360 (226%)

Pixel Rate

The GeForce GTX 950M should be much (about 422%) better at full screen anti-aliasing than the GeForce GT 430 (OEM), and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 11824 (422%)

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 (in units of megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
