Taking on ARM with Moorestown
While Menlow uses a more traditional PC setup (cpu + chipset), its successor due out in 2009/2010 won't. Moorestown, like Menlow, is a two-chip design - composed of a north hub and a south hub. The north hub features the CPU, memory controller and graphics, while the south hub is just I/O. This should sound a lot like AMD processors today, but there's one key differentiator: the south hub won't support the PCI bus.
The lack of PCI support is purely a power savings measure; while Intel expects Menlow to be far faster than the ARM platforms used in smartphones today (approximately 2x the performance of what's in the iPhone), ARM will continue to have a significant power consumption advantage.
While there will still be some Menlow devices that run Windows, Intel expects all Moorestown devices to run Linux.
Intel expects that in 2 - 3 years, thanks to reduction in die size and thermals, that it will be in a device the size of the iPhone. Until then we'll have to deal with larger MIDs for Menlow and the candy bar form factor we saw at last year's IDF.
