Emulation is SLOW.

They would be running a JIT to translate the code. Emulators and JITs have got quite good but x86 is a difficult ISA to do well. An interesting case which tends to to be bad is emulating a JIT as each half changes the code. Games tend to be dominated by graphics which would be done by the GPU and other stuff mostly spends most of the time in the system and Microsoft will make sure all its stuff works okay. Still there should be plenty enough problems for Intel to make hay out of it.
