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.
2004-06-21 Intel Alderwood 925X High-end chipset, succeeding Canterwood for Prescott and Tejas, while Grantsdale handles the "mid-end". ECC support was present, but has been removed from roadmaps. Priced at $50.
A faster version called i925XE with 1066 MHz will be launched in Q3/Q4.
2004-06-21 Intel Grantsdale 910/915 Desktop chipset for Prescott and Tejas (the Socket T or LGA775 processors). Supports DDR-II SDRAM (400/533) and the ICH6 south bridge. Graphics is enhanced with DX9 and DVI support, dual displays, faster graphics access etc and is called "Graphics Media Accelerator 900" (or GMA900), formerly known as "Intel Extreme Graphics 3". Will be launched as
- 915P ($37)
- 910PL: "light" (05-Q1: $23)
- 915G: added graphics ($41)
- 915GV: value graphics (Q3, $37)
- 910GL: value graphics "light" (05-Q1: $27)
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.
