GeForce GT 440 1.5GB		56 Watts
GeForce GTX 650 Ti 2GB		110 Watts
	Difference: 54 Watts (96%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 650 Ti 2GB should theoretically be a lot superior to the GeForce GT 440 1.5GB overall. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 43200 (100%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be much (approximately 317%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 45136 (317%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 650 Ti 2GB is superior to the GeForce GT 440 1.5GB, but it probably won't make a huge difference. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 592 (4%)

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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
