It's a nice chip, but would have been SO MUCH better if it has been available to board-makers in September 2021, as originally planned for the BeagleV "Starlight", not in January 2023.
In 2021 it was clearly a much faster alternative to the Allwinner D1 with a single 1.0 GHz core, which had started arriving in customer hands in late June. The D1's C906 core had a vector unit, but that was the only real advantage.
Now in the first half of 2023 the Pi 3-class JH7110 is running up against the Pi 4-class TH1520.
The VisionFive 2 and Star64 started arriving in the hands of customers in February and April, while the considerably faster (higher MHz and OoO, plus vector units) TH1520-based LicheePi4A started arriving in May. There will no doubt be other TH1520 boards soon too.
So far the 8 GB JH7110 boards are roughly $40 cheaper than an equivalently outfitted 8 GB TH1520 board. Perhaps the effective difference is more than that as as VisionFive 2 and Star64 have M.2 or PCIe while the LP4A doesn't.
So maybe there is a place for both. Let's see what price the Mars will be.
