"Performance equivalent to some CPUs found in PCs."
I like that kind of precise statement of performance, a.k.a. markerting speak: It sounds nice, but then some PCs might be construed to include our old 80286 processor running at 12 MHz. We even did image processing on that PC. Still use some of that code today, and it runs like the clappers on new kit. Somehwere in the corner of my office lurks a 80486 at 60MHz. I do not think anybody would like that kind of performance in their tablet or phone.
It would sound better if they had used the phrase "some current PCs, or actually stated which processor they meant.
Still, chips with better performance at lower power are always welcome.
