GeForce GTX 1050 Ti		75 Watts
Radeon HD 5850		151 Watts
	Difference: 76 Watts (101%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5850 will be 12% quicker than the GeForce GTX 1050 Ti overall, due to its greater bandwidth. (explain)

Radeon HD 5850		128000 MB/sec
GeForce GTX 1050 Ti		114688 MB/sec
	Difference: 13312 (12%)

Texel Rate

The GeForce GTX 1050 Ti will be a small bit (more or less 19%) more effective at AF than the Radeon HD 5850. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
Radeon HD 5850		52200 Mtexels/sec
	Difference: 9720 (19%)

Pixel Rate

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

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 5850		23200 Mpixels/sec
	Difference: 18080 (78%)

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 largest amount of data (measured in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
