GeForce GT 240 GDDR5 1GB		70 Watts
GeForce GTX 950		90 Watts
	Difference: 20 Watts (29%)

Memory Bandwidth

In theory, the GeForce GTX 950 will be 94% faster than the GeForce GT 240 GDDR5 1GB overall, because of its greater data rate. (explain)

GeForce GTX 950		105728 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 51328 (94%)

Texel Rate

The GeForce GTX 950 should be much (approximately 179%) faster with regards to texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 31552 (179%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 950 is the winner, and very much so. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GT 240 GDDR5 1GB		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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it must 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
