Intel Unveils Moorestown and the Atom Z600, The Fastest Smartphone Platform?by Anand Lal Shimpi on May 4, 2010 11:54 PM EST
The World Changes, MIDs Ahead of Their Time
Silverthorne lacked integration, which wasn’t a problem for MIDs and netbooks, but it kept the chip out of smartphones. Between 2004 and Atom’s introduction in 2008 the iPhone happened. All of the sudden the clunky MIDs we were reluctantly waiting for stopped being interesting. What we wanted were more iPhones, and iPhone clones. Then came Android and the rest is history. While Atom had tremendous success in netbooks, Intel’s decision to pursue a discrete route first kept it out of smartphones.
Luckily, next on the list after the first Atom was a more integrated one with the goal of dropping power consumption. We saw this with Pine Trail, the netbook Atom that brought the memory controller and GPU on-die. Performance didn’t improve because unlike most integrated memory controllers, this one still connected to the CPU via a FSB.

Pine Trail still has all of the bells and whistles of a PC platform however. Take the PCI bus for example. Every 12 microseconds it wakes up and polls every IO on the platform. That kills idle battery life, especially when you’ve got a tiny smartphone battery. Pine Trail is useless for smartphones, and that’s where Moorestown comes in.
If you thought this was the netbook Atom squeezed into a smartphone, you’re very wrong. It’s got a completely different memory controller, a true smartphone GPU (the same core, but clocked higher than what’s in the iPhone 3GS) and a ton of power optimizations that just don’t exist in the netbook version. The chipset is also very different. The PCI bus is gone as is anything that could ruin power consumption. Intel did a lot of optimization and a lot of cutting here. What resulted is something that looks a lot like a smartphone hardware platform and nothing like what we’re used to seeing from Intel.
This is Moorestown.
