Intel's advantages: lower and/or better at coping with heat, not currently limited to 2-way SMP, nearly unkillable when paired with an Intel chipset. Intel still owns the server market, as AMD is still in their first venture here. People aren't easily pursuaded to jump to a new platform if the current one is working fine. Intel is also a much bigger company than AMD. Both make more than just CPU's, but Intel just makes more stuff period.
