Intel has added few more new naming schemes this year with their processor lineup, and it has been confusing to keep track of what exactly is what. I’m putting this together to set the record straight.
Intel has two main processor families:
- Core processor family (go faster)
- Core i3/i5/i7
- Core M (ultra-low power, fanless, newly available in Q4 2014/Q1 2015)
- Atom processor family (less power hungry, possibly fanless)
- Atom x3/x5/x7
They have recently rebranded Rockchip processors into the Atom processor family as of 2015:
- Atom branded Rockchip processors in the Atom processor family
- Atom x3 ‘RK’ series
Celeron and Pentium Don’t Mean Anything
Celeron and Pentium CPUs can below to either of these Intel Core or Atom processor families, ever since 2013, rendering these brands useless. The only way to tell what is what is to lookup the CPU model on Intel ARK and CPU World.
- Celeron N2820 – dual-core Atom processor family
- Celeron 2955U – dual-core Core processor family
- Pentium N3540 – qual-core Atom processor family
- Pentium G2020T – dual-core Core processor family
This also means that you have two Celeron branded devices that perform very differently despite being at similar price points. This has been going on for a while now, but apparently not everyone is aware of this.
Atom Branded Rockchip Processors – 2015
As of MWC2015 (source Anandtech), they’ve also announced an Atom branded processor family of rebranded Rockchip processors within the Atom x3 lineup. These are low-end inexpensive processors for mobile devices mostly running Android that generally perform worse than and are less power efficient than their true Intel Atom equivalents.
