[Arm-netbook] SoC warp soldering risk?

[Bill Kontos]

Where does the 40% improvement come from ? I remember watching a video from
 Berkeley student where the improvement was "only" 11%.

The kirin 960 was a complete fail on their part. They downgraded the
manufacturing node to one that has a lower frequency sweetspot but lower
cost as well... still 14nm for whatever it's worth these days. On top of
that, and especially on the gpu side they have very aggressive clock steps,
even missing the efficiency sweet spot and resulting in peak draws of up to
10 watts. All for benchmarks on reviewing websites, most reviews just run a
benchmark once and show the result but do not test overheating. Totally not
suitable for eoma, no matter how much of a sucker for high performance I
am.
