GeForce GT 240 GDDR5		70 Watts
Radeon R7 370 4G		110 Watts
	Difference: 40 Watts (57%)

Memory Bandwidth

In theory, the Radeon R7 370 4G should be 229% faster than the GeForce GT 240 GDDR5 overall, due to its higher data rate. (explain)

Radeon R7 370 4G		179200 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 124800 (229%)

Texel Rate

The Radeon R7 370 4G should be a lot (approximately 255%) faster with regards to AF than the GeForce GT 240 GDDR5. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 44800 (255%)

Pixel Rate

The Radeon R7 370 4G should be quite a bit (about 609%) more effective at AA than the GeForce GT 240 GDDR5, and able to handle higher resolutions better. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 26800 (609%)

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 megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
