It seems apparent to me that the strengths of desktop chip manufacturers don't translate well to mobile. Both Intel and Nvidia have had tremendous problems to compete against ARM / PowerVR. While Nvidia has done a better job, I imagine they are still loosing money on that front. Maybe this is the time for them to acknowledge that and instead concentrate on markets where local data parallel computations are actually useful and currently feasible (due to power requirements). Maybe mobile might get there as well (real time on-chip image recognition), but it's still years off I think.
Well at least they have some performance benchmarks to show for [1] (I wasn't able to find a comprehensive sustained performance-per-watt comparison though, which would be much more interesting) and at least they sold more than half a billion dollars worth of Tegras in 2015. Looking at [2] that's at least substantially more than Intel sold when their mobile business crashed and burned in 2014 [3]. It's however not as much as Intel sold in 2013 and the last quarter of 2015 wasn't good for Nvidia either. Maybe it's fair to say that Nvidia is just learning the same lesson with a bit of delay, but at least they have a very strong pivot going after the car market with rapidly increasing compute requirements.
In recent years, Google Pixel C, Nexus 9, Nexus 7 (2012), that Project Tango tablet, and Nvidia's own Shield devices (TV, tablets, handheld). See: https://en.wikipedia.org/wiki/Tegra
Not the best-selling lineup, but a fair amount of developer mind-share thanks to Google's penchant for Nvidia SoCs and Nvidia's own outreach.
Delivering good chips for mobile use? Yes. Tegra chips have been showing good results in benchmarks.
But making money out of them? Not so much. The whole mobile chip industry became a race to the bottom (with prices) many years ago and most companies in the business are struggling as Samsung and Apple make their own chips and the rest of the market isn't worth a lot of money.
They had some wins with the Tegra line... Tegra 3 was pretty big in tablets and phones a few years back. Not sure how well it's going currently. But much better than mobile Atoms for sure.
