A revamped Pentium M release is expected next month after the processor was delayed earlier this year due to manufacturing problems. The code-named Dothan chips will double current cache size at 2MB and are expected to surpass the 2GHz mark, while models running at lower speeds are also expected for lower priced notebooks. The upcoming Dothan chips will also be the first to bear Intel's new model numbers. The 1.8GHz Dothan will be sold as the Pentium M 745 while the 1.7GHz version will be called the Pentium M 735. For years, Intel has rated chips by their megahertz. Megahertz, however, is only one factor in performance. In switching the model numbers, Intel follows rival Advanced Micro Devices.
