GeForce GTX 1050		75 Watts
GeForce GTS 450 1GB		106 Watts
	Difference: 31 Watts (41%)

Memory Bandwidth

Theoretically, the GeForce GTX 1050 should perform quite a bit faster than the GeForce GTS 450 1GB overall. (explain)

GeForce GTX 1050		114688 MB/sec
GeForce GTS 450 1GB		57728 MB/sec
	Difference: 56960 (99%)

Texel Rate

The GeForce GTX 1050 should be a lot (more or less 116%) faster with regards to anisotropic filtering than the GeForce GTS 450 1GB. (explain)

GeForce GTX 1050		54160 Mtexels/sec
GeForce GTS 450 1GB		25056 Mtexels/sec
	Difference: 29104 (116%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1050 is the winner, and very much so. (explain)

GeForce GTX 1050		43328 Mpixels/sec
GeForce GTS 450 1GB		12528 Mpixels/sec
	Difference: 30800 (246%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that 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 Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
