GeForce GT 440 3GB		56 Watts
Radeon R9 M295X		125 Watts
	Difference: 69 Watts (123%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X is 307% faster than the GeForce GT 440 3GB overall, because of its greater data rate. (explain)

Radeon R9 M295X		176000 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 132800 (307%)

Texel Rate

The Radeon R9 M295X should be a lot (about 573%) better at texture filtering than the GeForce GT 440 3GB. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 81744 (573%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M295X is superior to the GeForce GT 440 3GB, and very much so. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 9744 (68%)

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 information (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If 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 texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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