The Pentium 4 Extreme Edition was launched in x of xxxx as a range topping performance model. At 3.2GHz on Socket 478.
This chip was based on the Gallatin-2M core as used in the high-end Xeon processors. This gave some improvements in performance per clock and with the appropriate cooling they were able to reach 4GHz.
The degree of performance improvement depended on the type of application, the L3 cache reduced the need to page to memory but was still higher latency than L2. Gaming and office applications saw small gains but media encoding was the main benefactor.
A 3.4GHz version came on xxth xxxxxxxxx, 200x and represented the pinnacle of Socket 478 performance.
The move to LGA775 saw the 3.4GHz Gallatin-2M carried over, and then later a small speed bump to 3.46GHz but more significantly a 1066MHz Front Side Bus (4 x 266MHz).
Finally a 3.73GHz, Prescott-2M based Extreme Edition came in xxxxxxxxxxx, xxxx. This didn't have any enhancements over the standard Pentium 4 Hyper-Threaded Prescott-2M's except for the use of the 1066MHz Front Side Bus.
