Above you can see a Penryn die, but until those chips arrive in the November timeframe, Intel has another ace up it's sleeve: a Core 2  processor for the MP (4-way) server market.

Since the release of the Opteron, AMD has enjoyed several years of leadership in this profitable segment, and the launch of Barcelona was meant to consolidate that position. Unfortunately for them, Intel has plans to hold a launch briefing next Wednesday with Dell, Hewlett-Packard, IBM and Sun Microsystems, to preview Tigerton. Just a few days ahead of Barcelona.

Tigerton will be more powerful and power-efficient than the Netburst microarchitecture it replaces. Intel has already made the transition to Core 2 in its desktop, notebook and dual-processor server products, but is still selling chips for multiprocessor servers based on Netburst.

You can take a look at models, clock speeds, cache sizes and prices here (DigitTimes), but unless you own a server board you can forget about running one of those.

The Xeon 7300 series will have about twice the performance of Tulsa and over twice the performance per watt of these processors. The Tulsa chips are still based on the old Pentium 4 (good riddance).
