The system bus, which controls the speed at which data is exchanged among components on the processor, will be boosted from 100MHz to 200MHz, said Mark Miller, an Intel spokesman.
The new chip will be known as the PXA255, replacing Intel's existing top-of-the-line chip, the PXA250. The PXA255 will run at the same clock speeds as the PXA250 - 200MHz, 300MHz, and 400MHz - for the same prices.
It is likely to come out before Intel's next major release from its wireless communications group, the Manitoba processor.
Manitoba will combine flash memory, a microprocessor and a digital signal processor on a single chip, allowing manufacturers to build smaller mobile phones with wireless data capabilities.
