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.
