SAN JOSE, Calif. - Intel Corp. and Advanced Micro Devices Inc. on Monday will start selling the fastest models yet of their flagship processors, the electronic brains of personal computers.<br>
<br>
Intel's new top Pentium 4 chips run at 2.2 gigahertz and 2 GHz, or 2.2 and 2 billion of cycles per second. AMD's latest, the Athlon XP 2000+, clocks in at 1.67 GHz.<br>
<br>
Despite the speed difference, AMD says its Athlons are more efficient and perform better than faster Intel chips when it comes to running many of the most popular applications.<br>
<br>
But Intel's new chips are the first to be built using a new process that allows smaller transistors and other features, including doubled on-chip memory and a 30 percent reduction in overall processor size.<br>
<br>
That means the chips have a performance boost of roughly 10 percent, in addition to the boost that comes from increased processor speed, said Louis Burns, general manager of Intel's Desktop Platform Group.<br>
<br>
Analysts also expect the new process technology to help Intel meet demand for the Pentium 4 as well as improve profit margins by increasing the number of chips produced from each silicon wafer.<br>
<br>
"The cost structure is better. And they'll get more performance out of them," said Hans Mosesmann, an analyst at Prudential Securities. "It's a very good deal for Intel."<br>
<br>
Intel's previous top chip was the 2 GHz Pentium 4, which was introduced in August. It was built using the older process technology.<br>
<br>
The 2.2 GHz Pentium 4 will cost $562 when purchased in volumes of 1,000. The new 2 GHz chip is priced at $364 in volumes of 1,000. The Athlon XP 2000+ costs $339. <br>
