Radeon R7 240		30 Watts
GeForce 9500 GT 512MB GDDR3		50 Watts
	Difference: 20 Watts (67%)

Memory Bandwidth

In theory, the Radeon R7 240 is 13% faster than the GeForce 9500 GT 512MB GDDR3 overall, due to its higher data rate. (explain)

Radeon R7 240		28800 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 3200 (13%)

Texel Rate

The Radeon R7 240 is a lot (more or less 66%) faster with regards to texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 5800 (66%)

Pixel Rate

The Radeon R7 240 is a lot (approximately 33%) more effective at full screen anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 1440 (33%)

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 transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at 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 video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
