Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 650 Ti 2GB should theoretically be much superior to the GeForce 940M in general. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 70400 (440%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be quite a bit (about 131%) better at anisotropic filtering than the GeForce 940M. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 33664 (131%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti 2GB is superior to the GeForce 940M, and very much so. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 6272 (73%)

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 MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of 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 output 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 maximum fill rate.
