Are these even sold today? Outside of embedded systems I mean.

Not for desktop use, no. Probably the most powerful example remaining will be some sort of DSP designed for predictable cycle-accurate timing.

Arm Cortex-R series is intended to very hard real-time, and do branch prediction only if explicitly enabled

> However, the Cortex-R7 and Cortex-R8 do not enable branch prediction automatically at reset. This means software must enable branch prediction to get the maximum hardware performance.
