RISC-V Mainboard For the Framework Laptop 13 Is Now Available (liliputing.com) 5
The DeepComputing RISC-V Mainboard that Framework announced last year for its 13-inch laptops is now available for $199. Liliputing reports: If you already have a Framework Laptop 13 with an Intel or AMD motherboard, the new board is a drop-in replacement. But if you don't have a Framework Laptop you can also use the mainboard as a standalone computer: Framework sells a $39 Cooler Master case that effectively turns its mainboards into mini desktop computers. The RISC-V Mainboard comes from a partnership between Framework and DeepComputing, the Chinese company behind the DC-ROMA laptops, which were some of the first notebook computers to ship with RISC-V processors.
The board features a StarFive JH7110 processor, which is a 1.5 GHz quad-core chip featuring SiFive U74 RISC-V CPU cores and Imagination BXE-4-32 graphics, 8GB of onboard RAM, and a a 64GB SD card for storage (there's also support for an optional eMMC module, but you'll need to bring your own). Since the board is designed to fit in existing laptop frames, it's the same size and shape as AMD or Intel models and has four USB ports in the same locations. But these ports are a little less versatile than the ones you might find on other Framework Laptop 13 Mainboards [...]. There's also a 3.5mm audio jack. You can check out the new board via the Framework Marketplace.
Further reading: Late last year, Framework CEO Nirav Patel delivered one of the best live demos we've ever seen at a tech conference -- modifying a Framework Laptop from x86 to RISC-V live on stage.

How do these compare ? (Score:2)
How does this "a StarFive JH7110 processor, which is a 1.5 GHz quad-core chip featuring SiFive U74 RISC-V CPU cores" compare with an Intel or AMD running at 1.5GHz ? I would like to know how much work they can do (eg SPECspeed) and how much electricity they use (especially important in a laptop).

Check this out, it should be pretty close:

Framework's price is better than I was expecting.

The performance is crap. They really suffer from a lack of useful addressing modes. The only RISC-V CPUs that perform competitively are the ones from Huawei, but they use almost all the instruction set extension space adding addressing modes you need to handle common patterns efficiently.

Same model of CPU as my StarFive board. I should dump the source code and see where I went wrong.
But some memorable panics were had...
