Interesting. It'd be nice to know if they're going to focus on HPC loads or hobby/consumer too. I should check to see if I still know people around the BSC :P
From the preprint [1] it looks like it is not meant for consumers.
This way, Sargantana lays the foundations for future RISC-V based core designs able to meet industrial-class performance requirements for scientific, real-time, and high-performance computing applications.
