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.

yyeah, that's no surprise. what's really nice about RISC-V btw is that it's something mad like a 40% performance-watt improvement over ARM in the same geometry.
( like the kirn 960) and we are rather limited by the fact that everything has to run on libre software
well, there are plenty of companies that _don't_ (so it makes no sense to copy them or compete with them).... and the burden is enormous on absolutely everybody. yet nobody's even *tried* an entirely libre approach *despite clearly knowing the advantages*!
