The price hikes are due their tarket markets, not due to increased manufacturing cost. With the 2MB Xeon MP, you're paying for 4-way SMP support. The Opteron 146 and 846 share the same die and clock speed (with 8-way MP support fused off on the former), though their respective prices are $669 and $3199.
There's no reason to think that this Pentium 4 will share the same price, or anywhere near it, as the 2.8 GHz Xeon MP.
