Theoretically speaking, the GeForce GTX 1050 3GB should be 49% quicker than the GeForce GTS 450 in general, because of its higher data rate. (explain)

GeForce GTX 1050 3GB		86016 MB/sec
GeForce GTS 450		57728 MB/sec
	Difference: 28288 (49%)

Texel Rate

The GeForce GTX 1050 3GB is quite a bit (about 167%) more effective at AF than the GeForce GTS 450. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
GeForce GTS 450		25056 Mtexels/sec
	Difference: 41760 (167%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1050 3GB is superior to the GeForce GTS 450, by far. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
GeForce GTS 450		12528 Mpixels/sec
	Difference: 20880 (167%)

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 (measured in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
