What is the battery life like; maybe in ops/kwhr? https://news.ycombinator.com/item?id=40719630

The JH7110 CPU and 8 GB RAM on e.g. the VisionFive 2 uses about 5W of power at full load.

Battery life is going to be determined by your screen brightness, not the CPU.

From the reddit link in my this flgged (?) comment:

> About three years ago, I came across information that the RISC-V U74 core had roughly 1.8 times lower performance per clock compared to the ARM Cortex-A53.

Are there other advantages?

What is the immediate marginal cost of an ARM license per core(s)?

Likely to do with such information being unsourced, and contradicting every documented benchmark.

U74 does very easily outdo A53 in performance, power and area.
