2005-04-18 Intel Pentium D Dual core processor replacing Tejas. Smithfield is the Workstation / gaming implementation of Paxville, part of the Lyndon platform. Uses the LGA775 socket and the Glenwood and Lakeport chipsets. Based on the NetBurst / Pentium 4 architecture but without HyperThreading. Basically two Pentium 4 chips on one die.
Launched in Q2 at 2.8, 3.0 and 3.2 GHz named 820 ($241), 830 ($316) and 840 ($530) respectively.
Launched as 'Pentium D' and 'Pentium EE', where EE adds HyperThreading.
2006-01-05 Intel Presler 65 nm chip dual core chip including Vanderpool (a virtualization technology) to succeed Smithfield. Likely to run at 3.6 GHz and above. Previously known as Blue Pressler. Is in fact two Cedar Mill chips bonded together. Uses the i975X chipset.
2006-Q1 Intel Cedar Mill 65 nm processor Prescott-shrink, fill the gap between Prescott and Conroe. Said to be prepared for dual cores but will start off as a HyperThreading (dual threads) supporting single core chip. Newer info says that it is half a Presler. A value version with 512 KB of L2 cache, no HyperThreading and a slower bus is also rumoured.
2006-07-27 Intel Conroe Major redesign of the desktop chips based on the mobile chip Merom. Should use the same bus as Merom and Tukwila. Part of the Averill platform. Said to be used in future Macs. Will be named E6300 (1.86 GHz, 2MB, $210), E6400 (2.13 GHz, 2MB, $230), E6600 (2.40 GHz, 4MB, $315) and E6700 (2.67 GHz, 1066 MHz, 4MB, $529). A value-segment version known as Conroe-L will be introduced in 2007-Q2. Will also be used in Uniprocessor Xeon chips (3040, 3050, 3060, 3070)
2006-07-27 Intel Merom Mobile processor succeeding Prescott-M and Yonah built on a 65 nm process. Accompanied by the Crestine chipset. Recent rumours claim that Merom is a major new core design with multiple cores and, depending on version, 2-4 MB of cache, which will also form the base for the next desktop chip, Conroe. Said to consume about 45W.
Earlier said to launch in 05-H2 or 2007, prototype chips has been out since May of 2006.
Merom is part of the Santa Rosa Centrino platform, succeeding Napa. Said to be used in future Macs.
Bus speed to go up to 800 MHz in 2007-H1.
Will be named T7600, the T7400, the T7200 and T5600.
