GeForce GT 440 3GB		56 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 54 Watts (96%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 650 Ti should theoretically be quite a bit superior to the GeForce GT 440 3GB overall. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 43200 (100%)

Texel Rate

The GeForce GTX 650 Ti is quite a bit (more or less 317%) more effective at AF than the GeForce GT 440 3GB. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 45136 (317%)

Pixel Rate

The GeForce GTX 650 Ti is just a bit (about 4%) more effective at FSAA than the GeForce GT 440 3GB, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce GT 440 3GB		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: Bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount 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 most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
