Intel 2.4ghz Pentium 4 Northwood
Tuesday, April 02, 2002
While AMD continues to push their Athlon XP chips along in 66mhz increments, Intel has pressed-on in great strides of 200mhz. The results have been compelling. In the last few months, we've seen the release of Northwood CPUs operating at 2ghz, 2.2ghz, and now 2.4ghz - while the AMD Athlon XP trails along at 1733mhz.
If things keep up at this pace, Intel will break the 3Ghz mark before AMD hits 2Ghz.
Since we've covered most of the core technology behind the Intel Pentium 4 processor in the past, today, will be concentrating primarily on performance measurements, with only a brief summation of the P4s core features. Essentially, the new "Northwood" chips differentiate themselves from their predecessors through their 512KB L2 caches, and 0.13 micron manufacturing process. The previous generation of the P4 came with 256KB of L2 cache, manufactured using a 0.18 micron process. As expected, the "Northwood's" decrease in size resulted in a substantial decrease in energy consumption, and heat dissipation. Other noteworthy features are highlighted below.
The Intel Pentium 4.
The Pentium 4 is a fundamentally different beast when compared with the Pentium III. Since the technologies behind the two are quite different, we've already prepared a substantial introduction to the Pentium 4, which can consult by clicking on the link.
The following are the main characteristics of the 2.4ghz Pentium 4 "Northwood" CPU:
Cache L1 = 8k
Cache L2 = 512K
FSB = 100mhz quad pumped
Line width = 0.13 micron
Support for SSE2
Voltage drawn = 1.5 volts
Current consumed = 49.8 amps
Power dissipation = 57.8 watts
Now, with that cleared up, its time to get on to the main event: the performance analysis. When you consider that we've had this little bundle of joy on-hand for nearly a month, you can readily imagine how eager we are to share our results...
