AMD today unveiled a 750Mhz version of its low-end Duron processor aimed at small businesses and home users.
The Duron family was launched in June this year and has so far been available at speeds of 700Mhz, 650Mhz and 600Mhz.
AMD claims that Duron chips provide up to 25 per cent more performance on many industry benchmarks than Intel Celeron processors at the same clock speeds.
According to AMD, more than 20 computer manufacturers, including Fujitsu-Siemens, are offering systems based on the processors today. Compaq and IBM are planning to launch 750Mhz-based systems in the next few weeks.
PCs based on the latest chips will typically cost less than $1000, said AMD.
Duron is the enhanced version of AMD's Athlon processor and features 192Kb of total on-chip cache, a high-speed 200Mhz front-side bus, and a superscalar floating point unit - a chip within a chip that enhances performance - with enhanced 3Dnow technology.
AMD hopes that Duron will help it break into the business market, an area where it has so far been unable to enter.
Richard Baker, regional marketing director for AMD's PC products division, has previously said the chip is "where we are expecting to make our big push into the business market".
Andy Brown, a senior analyst at industry researcher IDC, said: "With Duron, AMD is possibly trying to pre-empt Intel's Timna launch, which is due at the beginning of next year."
Intel has had to postpone the launch of its low-end Celeron chip, Timna, to the beginning of 2001 because of development problems.
