Well, it seems that Intel has decided to release the Pentium4 2.0GHz processor today and there are a number of sites that have reviews posted already, so here we go...
The Tech Report:
"Last we checked in a big processor benchmark roundup, the 1.8GHz Pentium 4 was trailing close behind the 1.4GHz Athlon. Since then, AMD has laid low, holding back on releasing a new Athlon speed grade. If the Pentium 4 2GHz can catch the 1.4GHz Athlon, Intel will have pulled off a neat double play, reaching 2GHz and retaking the performance lead at once."
"Today we are debuting the Intel Pentium 4 running at 2.0Ghz, however this chip is different then its predecessors. It features the Socket-478 design and runs on a new motherboard from Intel (D850MV or D850MD). Also, the new Pentium isn't just another ramp up in speed; it's the next step in the Pentium 4 line."
"The only real difference for this iteration of the Pentium 4, other than clock speed, is the package. Intel's Micro PGA (mPGA) device, has 478 pins versus their legacy 423 pin package. This provides more power and ground pins, which will help provide a more robust power plane to the device and minimize noise with better grounding. As such, stable 2+GHz. speeds will be obtained."
"Shifting back to the present, the P4 has established itself in the high-end market and is available at the following speeds: 1.3GHz, 1.4GHz, 1.5GHz, 1.6GHz, 1.7GHz and 1.8GHz. Today, two more flavors are released to the public, namely the 1.9GHz and 2.0GHz Pentium 4. Although both CPU's are equal to their precedessors, with the only exception being the clockspeed, it is still a very interesting product because today, the first processor that breaks the 2GHz barrier is available in a store near you! At the same moment we are also looking at the last P4 based upon the "Willamette" core, which means it we'll be shifting to the 0.13 micron fabrication process soon. In a few weeks/months time, Intel will introduce their new "Northwood" core, which will be using the brand new socket478 package. The package gets smaller, and of course the actual processor will get smaller to, using a 0.13 micron die resulting in less power consumption and reaching higher clock speeds. With the launch of the socket423 P4 2.0GHz, Intel has also released the socket478 P4 2.0GHz. This one does not use the "northwood" core, it is still using the "willamette" core so it is basicly the same processor we are reviewing today, but in a different package."
"I still think that over $550 for a 2.0GHz Pentium 4 is way too much. The 1.8GHz is reasonable at a little over $250. Pricing is the major flaw of the Pentium 4, and that is what sets the 2.0GHz P4 apart from it's family. It simply costs too much to appeal to anyone but very high end system builders. Then again, the Intel-AMD price war is a totally different article. The price spread between a 2.0GHz Pentium 4 and the 1.4GHz Athlon (which we will be comparing it with) is over $430."
