GeForce GT 240 GDDR5		70 Watts
GeForce GTX 950		90 Watts
	Difference: 20 Watts (29%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950 should be 94% quicker than the GeForce GT 240 GDDR5 overall, because of its greater data rate. (explain)

GeForce GTX 950		105728 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 51328 (94%)

Texel Rate

The GeForce GTX 950 is much (more or less 179%) better at anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 31552 (179%)

Pixel Rate

The GeForce GTX 950 should be a lot (about 645%) faster with regards to FSAA than the GeForce GT 240 GDDR5, and capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 28368 (645%)

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 transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
