They explain very clearly in the previous linked blogpost [1] in OP. Some snippets > There is excellent philosophical alignment between RISC-V and Framework. Both are built on the idea that an open ecosystem is more powerful than the sum of its parts... x86 ... is used in the processors for each Framework Laptop ... The x86 ISA was invented by Intel, extended on by AMD, and is proprietary, with Intel and AMD being effectively the only two companies able to use and create processors around it. ... What makes RISC-V unique is that it is an entirely open architecture, which means that anyone can extend on it and create their own processors that use it without paying a fee. RISC-V International is the collaborative organization that exists to help develop the standard and define common versions to ensure cross-compatibility of hardware and software. There are hundreds of companies now developing cores and chips around RISC-V, but most of these have been hidden away in embedded applications.... > All of this is what makes RISC-V unique from an ecosystem enablement perspective. The actual technology is equally interesting. The base instruction set of RISC-V is simple and streamlined, while there are a number of extensions enabling high performance and specialized compute. This means that RISC-V cores can be developed for anything from tiny control CPUs embedded inside a sensor (the Fingerprint Reader we’ve used in Framework Laptops since 2021 actually has a RISC-V core!) to monstrous multi-hundred-core server processors. The DeepComputing RISC-V Mainboard uses a JH7110 processor from StarFive which has four U74 RISC-V cores from SiFive. SiFive is the company that developed CPU cores using the RISC-V ISA, StarFive is the processor designer that integrated those CPU cores with other peripherals, DeepComputing created a Mainboard leveraging that processor, and Framework makes laptops that can use the Mainboard. The power of an open ecosystem! [1] https://frame.work/ca/en/blog/introducing-a-new-risc-v-mainboard-from-deepcomputing https://frame.work/ca/en/blog/introducing-a-new-risc-v-mainb...
