Cheaper at the mothership - https://smile.amazon.com/Dell-Chromebook-celeron-Certified-Refurbished/dp/B07HMJY8NR/ref=sr_1_2?keywords=Dell+Chromebook+11-3120&qid=1581813143&sr=8-2
Mothership smothership… They’re different model laptops. The one from that link is single core and this one is dual core.
Both this page and the page I link to both show the model as the 3120 and both with the Intel Celeron N2840 processor. Where are you seeing a difference in the cores?
