Not sure if this was a rhetorical question or not, but: quite a few.  We have 
support for several highly threaded 64-bit MIPS systems including those from 
Cavium and Broadcom (was NetLogic Micro was RMI).  Several reference systems 
are in the netperf cluster including 16- and 32-thread systems normally 
deployed in high-performance network products.  It's possible that ARMv8 
systems will gradually displayce 64-bit MIPS systems in this arena in the 
future, but hard to say.  Either way, it's not x86. :-)
