Reports from news.com say that this new model supports SD IO, uses the Windows Mobile 2003 operating system, and it uses Samsung's 203MHz processor, rather than the 206MHz Intel chip found in the H1910.
That continues a trend by HP to go with Samsung's chip in its low-priced models. In addition to its lower cost, HP executives have said the Samsung processor outperforms Intel's XScale on a megahertz-to-megahertz basis. HP still uses XScale chips in its higher-end models.
John Dayan, director of HP's handheld business for the Americas region, said the H1945 with the 266MHz Samsung chip offers up to 87 percent higher performance than the H1910. "It (has) higher performance even with the 203MHz (Samsung) chip," he said, although some of the performance gain also is attributable to the operating system.
