I don't think the battery/CPU relation you posit is true - the A13 is faster in single-core performance than the Snapdragon 865 (or 855), but consumes more total power to do the same work: https://images.anandtech.com/doci/15207/SPEC2006_S865.png https://images.anandtech.com/doci/15207/SPEC2006_S865.png
I think all this tells you is that ARM's big cores chose a power/performance curve point well below the A13. The upcoming Cortex-X1 in next year's 875 will be their first attempt at breaking into that market.
- Spooky23 6y agoI’m not an expert in mobile CPU’s, but I know that those benchmarks are server benchmarks and aren’t designed for a mobile use case. Mobile CPUs usually have low power and high performance modes, and aggressively shed power loads when idle. I’m not sure what benchmark is appropriate, but I wouldn’t draw much from that one.
