Intel is preparing to launch ##"Tulsa," a dual-core Xeon MP processor## and the last of its chips built on its NetBurst architecture. Though it has been shipping Tulsa processors for revenue since earlier in the quarter, the Santa Clara company is expected to officially roll out Tulsa on Aug. 29, according to sources. Intel would not confirm or deny the date. The high-end processor, which is used in servers with four or more chips, is the latest volley in Intel's ongoing effort to slow down the momentum of rival Advanced Micro Devices, which introduced its latest generation of Opteron processors on Aug. 15.
