Couple of observations here; - RISC-V has miles to go, I worry that with the current pace of ARM it may never catch up. - The assertion you can’t buy UMPCs in 2024 is patently false. GPD and a whole host of manufacturers make em. - A non mobile optimised blog in this day and age? That was a chore to read on the go.

Only assuming development progress happens linearly. In fact, technical progress goes exponentially. It took years to even get to the point to have RISC-V SoCs and now we are seeing the first laptop products. The pace will accelerate, especially with the promise of RISC-V being a cheaper platform to build hardware on than ARM and X86.

Do you imply that chip is fake and does not work? :-)

Do you imply that there are no fake products on Amazon, which is also making chips (AWS Graviton)? Exactly the same issue: https://www.youtube.com/watch?v=y83BS_mK9GE

There is a reason why Aliexpress and Amazon suffer form the same curse.

I could get over the perf but the power consumption is rough. It seems strange that the USB hub is using so much power. From a (leaked?) data sheet I don’t see any way to disable it - but it does have firmware which can be updated? There is also a 5V-3.3V LDO built in so I wonder if that may be what is dissipating so much power. The AMS1153 looks like a similar story…

USB 3.0 can eat alot of power due to high speed, if it's always active...

Also the GPU doesn't have a free driver [currently]

The GPU doesn't have a closed driver that works either. It's been a year for the JH7110 too, so I wouldn't hold my breath. On Vision Five 2 everything is still softpipe in the official Debian from Star Five! On the PineTab-V NOTHING involving the 3D part of the GPU works! YouTube works for consumption, but that's not interesting for production. To write/film a review of a SoC with GPU without running glgears is backw…

>I think the only hope now is for the upstream to gain a working driver in a year or two.

PowerVR driver is already part of mesa3d mainline[0].

Some definitions for the variant used in JH7110 have been added recently, but it's not yet operational.

I have one of these as well - the distro I installed has a broken Chrome that crashes shortly after startup, hopefully that's fixed now. The case is prototype-quality but fine (the fact that it's metal helps a lot), the screen is nice, the keyboard is even more awkward than it needs to be for the size. I've been a bit disappointed by the performance in my tests (compiling various projects of mine with GCC), it seems…

Is JIT for JavaScript supported on RISC-V? This was an issue in PPC for a long time.

My tests show it's slightly slower than Pi 4 and significantly faster than Pi 3 on CPU performance. 1T Coremark: Pi 3: 3504 Lichee: 6900 Pi 4: 7938

have you tested its rv64v vector performance

Kinda hard to compare it against anything, but here are some benchmarks: https://camel-cdr.github.io/rvv-bench-results/milkv_pioneer/...
