2004-02-02 Intel Pentium 4E Also known as Prescott launches at 2.8 ($178), 3.0 ($218), 3.2 ($278) and 3.4 ($417) GHz with a 800 MHz front side bus and is built using a seven layer, Low-K, 90 nm Strained Silicon process.
Builds on the Netburst architecture, but adds "PNI" or Prescott New Instructions, which includes 11 new instructions, and LaGrande, a new security interface to go with Microsoft's Palladium. Also includes an improved pre-fetch branch predictor, improved HyperThreading, doubled L1 data cache size, doubled RAT History table size and advanced power manangement.
Will use Canterwood to start with, but in Q2 it will add the 64-bit CT Technology, move to Grantsdale and use the LGA775 socket.
Celeron Prescotts will be launched in Q2. Prescott reach 4 GHz in 2004-Q4 (now moved to 2005-Q1).
Now renamed Pentium 4E.
2004-05-10 Intel Dothan 90 nm successor to Banias, and the Centrino / Pentium M line, which will have a 400 MHz bus (533 in 05-Q1) and 2MB of cache. Will be called 735, 745 and 755 for 1.7 to 2.0 GHz processors costing $294, $423 and $637.
Slower (715 and 725) versions launch in Q3, and faster (760, 770: 533 MHz bus, up to 2.13 GHz) in Q4. Consumes 21W in performance mode. Earlier meant to launch in 03-Q3.
2004-06-21 Intel ICH6 South bridge including four PCI Express x1 ports, and eight USB 2.0 ports. The ICH6-R (+$3) will support four S-ATA ports, while the normal ICH6 only includes two. There will also be ICH6-W (+$5) and -RW (+$7) versions with wireless capabilities and a ICH6-M for Mobile systems. Uses the new DMI (Direct Media Interface) to connect to the North Bridges.
2005-01-19 Intel Alviso Chipset in Napa platform based on Grantsdale, but for notebooks succeeding Montara and Odem from the Centrino line. Likely to be available in several versions with (-GM) and without graphics. Earlier planned for 04-H2. G-version said to include the GMA900 graphics core.
Alviso is part of the Sonoma generation of the Centrino platform.
Napa64 is likely to be a Alviso with support for Merom.
