A couple notes - while the headline says it's an octa-core chip, it actually has 16 cores with different VLENs:

- 8× X100 cores @ 2.4 GHz (general-purpose, VLEN=256)

- 8× A100 cores @ 2.1 GHz ("AI-optimized", VLEN=1024)

By default, programs only run on the X100 cores, but there's a way to start processes on the A100 cores: https://github.com/sanderjo/SpacemiT-K3-X100-A100/blob/main/...

I believe this is the first RVA23-compliant RISC-V SBC on the market - excited to get my hands on one and test.
