The AMD SMP chipset has something which alpha processors
has too. it can get/write words out of L2 cache from other processor,
without needing to wait to read/write to main memory.

The intel can't do this. It doesn't have the master/slave idea
from the alpha.

Also when running SMP the amd's profit more from their L1 cache than
the intel does, though this is less important than the alpha feature
the K7 has for SMP behaviour.

So even if it is *close* to each other. When you start running the
things SMP, then the P4 is history.
