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-Q1 Intel E7210 Canterwood-based chipset for servers. Adds PCI-X to the Canterwood capabilities. Previously known as Canterwood-ES
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)
2004-06-28 Intel E7520 / E7320 Xeon chipset supporting the 800 MHz front side bus made to support Nocona. Supports PCI Express, Serial ATA and DDR-II. The E7520 was previously known as E7710 and Lindenhurst while the slightly cheaper E7320 has been known as E7510 and Lindenhurst-VS.
2004-Q4 Intel E7221 Single processor chipset for workstations based on Prescott and possibly the processor succeeding Prescott. The chipset was formerly known as Copper River and succeeds Canterwood-ES
2005-03-29 Intel E8500 Server chipset made to accompany the 4-processor server (4S) chips Cranford, Potomac and later Paxville and Tulsa. Said to support PCI Express, Serial ATA and DDR-II. Also known as Twin Castle 4S.
