It's extremely unlikely Poser will be made compatible with ARM processors any time soon, if ever,

Arm processors are RISC. A completely different architecture from the CISC that the majority of computers. ARM processors are more in the realm of smart phones and smart devices. Comparing RISC and CISC by clock speed is probably actually deceptive advertising. An important component of CPU speed is it's IPC (Instructions per cycle) that's basically how much the CPU actually accomplishes with one of those millions of clock cycles. And ARM processor simply doesn't have the horsepower necessary for the heavy workloads of things like rendering and video encoding.
