I can understand why Intel did not go with the XScale ARM CPU before (license issues, some shortcommings in the microarchitecture, and Not-Invented-Here?), but I can not understand why Intel did not develop its own efficient RISC based CPU to complement the existing X86 CPU to gain new market shares, since many of the most advance RISC design techniques already exist in recent Intel X86 CISC family of CPUs. Unlike the Intel i860, i960 and the Itanium times when advance RISC techniques were still not very mature, the time has come that there are relatively less risks to develop a RISC CPU with great performance/cost and power saving requirements. It would be a shame if the top management team at Intel does not realise that the opportunity is now to develop the new RISC CPU to effectively address the markets where the X86 fails.
