N2840 is dual-core. They are both architecturally successsor of 'Atom' core family despite being labelled Celeron or Pentium. The brands are good for Intel to differentiate prices but useless for technical purpose. The same happens to AMD too. Acer provides model variations in CPU, RAM, storage, display, etc. according to geo markets. For example ES1-111 is only available with N2940 (another quad-core) here in Taiwan. If you can find a quad-core Baytrail model and don't mind slower single-thread performance, the E3 or ES1 series are easier to install FreeBSD I guess. Total multi-thread performance are comparable. And now prices do not differ much either, since Microsoft tax is lifted from these new cheaper models to compete with Chromebooks. -Jia-Shiun.
