Almost. SoC is a 1+4 design, with a vexriscv main core (350MHz), and 4 tiny "Baochip IO" PicoRV cores (700MHz) (somewhat akin to the ultra-puny Programmable IO/PIO cores on rp2350). The crowdsupply for this board just opened. For on vexriscv, which has been around: https://hn.algolia.com/?q=vexrisc

This is an embedded chip, not a full on application core like an arm cortex A78. No GPU, 2mb+256k onboard ram + psram external. But like a rp2350 there are graphics drivers. It has a ridiculously fast for its class internal execute-in-place flash. A rather featureful MMU for a device of its small size, to support it's rust based borrow-checked memory OS. Tons of security & encryption features such as sha256/512, blake2/3, ECC ram, TRNG, etc. 22nm doesn't sound impressive by modern standards but is pretty good for a small embedded chip; rp2350 is 40nm.

The BIO is going to be ridiculous. Fully cross barred to output and just ridiculously fast.

I want Oxide to start an RFD for evaluate changing their base processor to this ("Gimlet"). Much higher security than anything else available. Switching off Hubris is probably a non-starter, it probably lacks some nice/necessary peripherals, and major supply chain risk, but also, an incredible open source chip you could go deeper on.
