The beauty of Niagara is for applications which are thread-rich and can get the benefit from the low power & high performance for many threads acting upon a problem.In the desktop you might envision Niagara derivatives which use smaller die size and hit a design point which maximizes a performance design point for desktop apps while simultaneously minimizing the cost . You could also envision looking at the appropriate IO for the desktop and integrating it onto this new SOC. There are lots of possibilities here.
