Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 3GB		75 Watts
Geforce GTX 670		170 Watts
	Difference: 95 Watts (127%)

Memory Bandwidth

In theory, the Geforce GTX 670 should be 123% quicker than the GeForce GTX 1050 3GB overall, due to its greater bandwidth. (explain)

Geforce GTX 670		192000 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 105984 (123%)

Texel Rate

The Geforce GTX 670 will be quite a bit (more or less 53%) more effective at anisotropic filtering than the GeForce GTX 1050 3GB. (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce GTX 1050 3GB		66816 Mtexels/sec
	Difference: 35664 (53%)

Pixel Rate

The GeForce GTX 1050 3GB should be just a bit (approximately 14%) more effective at full screen anti-aliasing than the Geforce GTX 670, and also will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 4128 (14%)

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 (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
