Intel Atom x5 x5-Z8500 

Released January, 2015
  • 1.44 GHz
  • Quad core

Originally planned to be a dual-core only option, Intel has actually built both dual-core and quad-core variants that will pair with varying modem options to create a combination that best fit target price points and markets.

The SoFIA processors are based on the same Silvermont architecture as the current generation of Atom processors, but they are more tuned for power efficiency.
