It seems fairly clear to me that any processor which performs speculative execution will be vulnerable to timing attacks of this nature.
I was pointed to a very much simplified but very clear explanation of this in a blog post by Eben Upton (of Raspberry Pi fame): https://www.raspberrypi.org/blog/why-raspberry-pi-isnt-vulnerable-to-spectre-or-meltdown/ Well worth reading, and relatively accessible for people who aren’t super-nerds, so a good one to send to friends and family who are interested.

That's only 1 of the 3 attacks to my understanding. The Spectre paper says: # Hardware. We have empirically verified the vulnerability of several # Intel processors to Spectre attacks, including Ivy Bridge, Haswell # and Skylake based processors. We have also verified the # attack’s applicability to AMD Ryzen CPUs. Finally, we have # also successfully mounted Spectre attacks on several Samsung and # Qualcomm processors (which use an ARM architecture) found in popular # mobile phones.
