Other than it will be running Android, we do not know any of the hardware specs. Of course, there will be a Medfield Z2000-series processor, but it is unclear if Motorola is using the single-core, 1.6 GHz Z2460 or the dual-core Z2580, which can reach up to 2 GHz. At CES earlier this year, Intel claimed that the Z2460 can hold its own against the dual-core and quad-core rivals.
However, in a BBC article, there are more cautious notes about performance from Intel. "Faster speeds only get you so far," Mike Bell, Intel's vice president for mobile, told the BBC. "It's really all about user experience and the responsiveness of the device and less about speeds and feeds."
I will leave that up to you to interpret that statement, but it appears to be clear that Intel is not shooting for the performance crown in terms of raw processing power. Intel previously said that it has optimized Medfield to run Android well and that appears to be the company's greatest asset until its 22 nm Valleyview processors are unveiled in quad-core configurations in 2013.
