Theoretically speaking, the GeForce GT 340 1GB is 70% quicker than the GeForce GTX 950M in general, due to its higher bandwidth. (explain)

GeForce GT 340 1GB		54400 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 22400 (70%)

Texel Rate

The GeForce GTX 950M should be much (approximately 108%) more effective at AF than the GeForce GT 340 1GB. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 18960 (108%)

Pixel Rate

The GeForce GTX 950M will be quite a bit (approximately 232%) faster with regards to full screen anti-aliasing than the GeForce GT 340 1GB, and should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 10224 (232%)

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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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