The speedy processor will be built on the same so-called Coppermine core used in the current crop of Pentium III processors, which run at clock speeds up to 1 GHz, according to Graham Palmer, a spokesperson at Intel's United Kingdom office.
"This is an indication that the 0.18-micron Coppermine core with integrated cache [memory] is scaling very well," says Palmer.
Intel is working with several major PC vendors planning to use the 1.13-GHz processor in high-end PCs aimed at the enthusiast segment, he adds.
Similar to the 1-GHz version, the 1.13-GHz Pentium III will initially be available in limited volume only, with production to ramp up later in the year. It will be designed to support a 133-MHz front side bus, Palmer says.
Pricing information was not available.
Later this year, rival Advanced Micro Devices is also expected to introduce new Athlon processors running at clock speeds higher than 1 GHz. The two processor vendors have spent the past year trying to best each other in order to gain bragging rights for the speediest processor on the market.
Intel later this year is also scheduled to launch the Pentium 4, a new series of processors formerly code-named Willamette.
The first Pentium 4 versions are expected to run at clock speeds of around 1.4 GHz.
