Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
GeForce GTX 1050 3GB		75 Watts
	Difference: 11 Watts (17%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 3GB will be 8% quicker than the GeForce GTX 650 overall, due to its greater bandwidth. (explain)

GeForce GTX 1050 3GB		86016 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 6016 (8%)

Texel Rate

The GeForce GTX 1050 3GB is quite a bit (approximately 97%) more effective at AF than the GeForce GTX 650. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 32960 (97%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 1050 3GB is the winner, and very much so. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 16480 (97%)

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 (in units of MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at 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 card can possibly write to the 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 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 also depends on quite a few 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.
