My question is the performance between the S5e and the S6 if only one application is running because I am looking for the tablet which will just run the one task of rendering pdf files quickly. Will the performance of the snapdragon 855 greatly outperform the 670 if it is just running one program? Say, for instance, rendering a pdf file (zooming in and out of the pdf)? I wonder if the snapdragon 670 will be any slower if the pdf file is the only program running on the tablet because the faster chip is geared for multitasking and not necessarily a one on one in running a single program. Thanks in advance for understanding and responding to my question in layman's terms.

You will definitely notice the difference between these chips even in single core\thread performance. 855 in Geekbench 5 Single Core test shows more than 2 times better performance. Will it be 2 times better in your PDF example? It depends on many factors. In general, I think the perf. gains of 855 will be noticeable. But do you really need such power for opening PDF? Both of there chips will handle opening, zooming, scrolling large PDFs fine...
