Ever since AMD’s Thunderbird/Duron release in June, the CPU industry has been pretty quiet. There has been a lot of talk going around about memory technologies and chipsets, but as far as the processor clock speed race is concerned, things are not nearly as bad as they were leading up to the release of the first 1GHz chips from AMD and Intel.
AMD’s Thunderbird helped to narrow the performance delta that existed between the Athlons and the competing Pentium IIIs, thus placing more pressure on Intel to do something to regain either the performance or the clock speed advantage.
Towards the end of June, after AMD’s barrage of processor announcements and releases, Intel did attempt to steal the lime light for a bit by announcing that a faster Pentium III was on its way, once again, in “limited quantities.”
That time is now and the “faster” Pentium III happens to come clocked at 1133MHz, or 1.13GHz for short.
