> Celeron rather than an Atom CPU
This isn't very helpful as Intel calls some mainstream core based processors Celerons, and some atom core based processors Celerons.
The current trick is J before the four digit number is Atom based, U after the four digit number is mainstream laptop core. G before gives you mainstream desktop core for Pentium, and I think Celeron as well. But really just put the model number into search, go to the Ark page and see that it's products formerly Blah and then look up Blah to see what that actually means. Yay marketing.
