I love that the instruction decode unit's ability to command a flush on branch mispredicts is represented in the diagram as a toilet.

That's cool.

When can I buy an SBC with one, that's within one base-10 order of magnitude of the Raspberry Pi's price?

This is only a cpu core. It lacks the memory controller and peripherals that make a SoC work. It will probably never make its way into a chip tapeout.

I'm pretty sure that if you order 1 billion of them, they'll do you a good price.

Seems like maybe an inauspicious name for a CPU...

Ariane is the name of an entire family of rockets that are still being launched today and are not generally known for being unreliable.

They had a successful launch today in fact: https://spaceflightnow.com/2020/01/16/ariane-5-va-251-missio...

Last I heard they were also having a lot of trouble competing with the industry leaders...

Ariane was the most competitive / succeful private launcher for 20 years even in face of American companies.

SpaceX is however currently disruptive them, like every other actor of the industry.

Ya, that's what I heard. After spaceX started doing better than them, they were having trouble because they didn't want to start using reusable rockets.

I saw "6-stage" and "Ariane" in the title and got very confused...

Its an reference to the 'Rocket' program of Berkley. Also, overall Ariane is one of the savest rockets in human history.
