Display and User Interface Comparison
The ProForm Performance 800i has a 14″ Smart HD Touchscreen and the ProForm 705 CST has a 5″ Backlit Display. The Smart Performance 800i has a touchscreen which is great while the 705 CST has buttons for controlling the treadmill, so browsing the menus is not as easy as the Smart Performance 800i. We think the bigger screen size of the Smart Performance 800i is a plus. 
Built in Programs
The Smart Performance 800i has 28 more programs, 50 vs 22. Both treadmills are iFit Coach Compatible so you can get many different workout options.
Bottom Line
We gave the ProForm Performance 800i a rating of 95 over 100 while we gave 90 for the 705 CST because, the Smart Performance 800i has a touch screen, larger display, more programs, decline control, and a good price for the features you get.
