"Most" embedded ARM? Cortex-A8 and smaller do not have OoO execution. Cortex-A9 is a 32-bit up-to-quad core CPU with clock of 800MHz-2GHz and 128k-8MB of cache. That's pretty big. I guess a lot of this is subject to opinion, but I don't think smartphones with GBs of RAM when I think of embedded systems.

Even e.g. A53 is in-order, and it's a 64 bit, pretty quick CPU (as seen in Raspberry Pi 2/3).
