Dell Chromebook 3120 review

Four Gigabytes and a Top-Band Carry Score

The Dell Chromebook 3120 pairs a Celeron N2840 with 4 GB of memory — the smallest recorded memory pool in this batch — and still posts one of the highest portability readings in it: 92, top band. No listing price is recorded for this entry.

Where it holds up

Portability at 92 is the stand-out, and the graphics reading of 16.2 sits above the ultrabook median of 3.84 — though, as with its Chromebook 11 sibling that shares the same reading, that says more about the small median than about any real graphics capability. Performance lands at 11.17 and gaming at 28, both low band but not zero.

Where it falls short

Memory is the flagged weakness: 4 GB against a class median of 32, a level the sheet calls minimal — 87.5% below median, and the practical ceiling on every browser-heavy workload. Office reads 1.1, modeling 18, engineering CAD 19, photo design 21, all low band. Composite capability reads 11 against a median of 49. The portability tier it occupies — 92, second only to the Inspiron 11 3162's 94.6 in this batch — is the honest selling point, and the 4 GB pool is the honest ceiling. Everything else in the sheet sits where 2015-era education hardware sits: low band, without surprises. The N2840 it shares with the Chromebook 11 tells the same story twice.

Price and depreciation

No listing price is recorded and no depreciation curve is modeled for this entry.

Alternatives to consider

The Chromebook 3100 offers the same education build with a newer Celeron N4000 and a mobility reading of 99. The Chromebook 11 shares the N2840 and the 16.2 graphics reading with a lower portability score of 91.

Bottom line

Fairly priced for the class. The 4 GB of memory is the whole story: fine for one purpose, insufficient for two.
