Memory Bandwidth

Theoretically speaking, the GeForce GTX 950 should be 10% faster than the GeForce GTX 870M overall, because of its higher bandwidth. (explain)

GeForce GTX 950		105728 MB/sec
GeForce GTX 870M		96000 MB/sec
	Difference: 9728 (10%)

Texel Rate

The GeForce GTX 870M is quite a bit (more or less 114%) faster with regards to texture filtering than the GeForce GTX 950. (explain)

GeForce GTX 870M		105392 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 56240 (114%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 950 is a better choice, by far. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 870M		22584 Mpixels/sec
	Difference: 10184 (45%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
