Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 3GB		75 Watts
Radeon RX 570		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

In theory, the Radeon RX 570 should be 167% faster than the GeForce GTX 1050 3GB in general, due to its greater bandwidth. (explain)

Radeon RX 570		229376 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 143360 (167%)

Texel Rate

The Radeon RX 570 should be a lot (approximately 124%) more effective at anisotropic filtering than the GeForce GTX 1050 3GB. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GTX 1050 3GB		66816 Mtexels/sec
	Difference: 82688 (124%)

Pixel Rate

The Radeon RX 570 will be a bit (about 12%) more effective at full screen anti-aliasing than the GeForce GTX 1050 3GB, and also will be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTX 1050 3GB		33408 Mpixels/sec
	Difference: 3968 (12%)

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 largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once 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 amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 ability to get to the maximum fill rate.
