Intel Pentium 4 Northwood 2Ghz and 2.2Ghz
socket 478 processors comparison review

Monday, Januray 7, 2002


Coming on strong following the release of the first two generations of the Pentium 4 (the Socket 423 and Socket 478 versions, respectively), Intel has continued to floor the accelerator as they battle AMD for control of the desktop. Now, a new plateau has been reached with the release of the Pentium 4 "Northwood" - the first P4 to be based on a 0.13 micron process, and incorporating 512KB of internal L2 cache. As is most often the case, the reduction in size from 0.18 to 0.13 microns has also significantly reduced the P4's current consumption and of course, heat emissions. With that said though, let's say we take a brief tour of the "Northwood", before heading in to the meat of the review: the performance analysis.

The Intel Pentium 4.

A number of characteristics differentiate the Pentium 4 from the Pentium III; so many in fact that we consecrated an entire article to the subject, which you can refer to be hitting the link.


Below is a list of the principal distinguishing characteristics of the Pentium 4 "Nortwood" 2GHz, and 2.2GHz:

  • Cache L1 = 8k
  • Cache L2 = 512K
  • FSB = 100MHz quad pumped
  • Process = 0.13 micron
  • Support for SSE2
  • Required voltage = 1.5 volts
  • Required current = 44.3 and 47.1 amp¸res
  • Power dissipation = 52.4 and 55.1 watts

  • Without further ado then, let's hurry on to the review, shall we?
