Pretty much all high-performance processor designs are affected by some Spectre variant or other, as speculative execution is pretty near universal. IBM is making firmware patches for POWER9 available, with at least some level of mitigation (though not for some older POWER models, which they've desupported).

(Besides, it's not as if Intel is uniquely good at dealing with these sorts of vulnerabilities. The reverse, if anything -- meltdown was a particularly nasty variant which seems to have primarily affected Intel processors, and not even other manufacturers' x86 variants.)
