The duel between Intel and AMD for speed supremacy stepped up last month when Intel announced an 800MHz Pentium III due to ship this quarter.
Intel also announced a 750MHz chip, which is as fast as the newest AMD Athlon that earlier took the speed crown.
Intel was not expected to launch its 800MHz chip until later this year, but reports say it brought the date forward due to AMD's success in convincing PC makers that, despite production difficulties, it could deliver the Athlon processor.
While the 800MHz Athlon is due to ship this month, AMD has demonstrated two versions of the chip at 900MHz.
Both AMD and Intel are talking up a 1GHz chip for later in the year, and AMD has hinted that it will have the chip ready sometime in the second half of 2000.
But Peter Glaskowsky, analyst at Microdesign Resources, said announcing chips before they are shipped could harm companies as customers cannot buy products that include them for several months.
