That's right, the Realtek RTL8367RB-VB-CG is an ethernet switch chip, and so it certainly will allow for full speed switching, entirely internally.
It's not nearly as rare as all that, your basic OpenWRT-running 5-port router has the same setup. But those cheap SOHO routers aren't going to do really fast routing, because they typically come with very slow CPUs.
This board's Rockchip RK3568 looks pretty capable though.

IME, this kind of divided switching/routing setup became ubiquitous after gigabit became widely available. I remember that while buying my previous router (Cisco Linksys E4200), this architecture was advertised explicitly, and it was exclusive to E4200 in that generation of Cisco/Linksys routers.
The main firmware of E4200 was prone to crashing under some circumstances, so having a good network sans DNS was a good trade-off back then.
