What the Celeron G3900 is
The Celeron G3900 brings Skylake to LGA 1151 for office desktops with DDR4. It launched in 2015 with two cores at a fixed 2.8 GHz and 51 W. Intel targets task workers who need basic browsing and documents at a low price.
Two megabytes of Smart Cache carry light tasks. The fixed clock suits predictable office loads. Two threads cover a browser plus background services.
The process is 14 nm. The multiplier is locked. DDR4 and DDR3L in two channels feed the chip with up to 64 GB on capable boards. A boxed stock cooler ships with retail packs.
Shops value the part for fleets where price matters most. The 51 W rating fits slim towers. A 72 C case class suits ventilated offices with basic airflow.
Socket and motherboard compatibility
The Celeron G3900 fits LGA 1151 on 100 series boards with DDR4 or DDR3L slots. H110 and B150 boards list Celeron parts with display outputs. Makers add Skylake IDs with 2015 BIOS builds.
LGA 1150 boards cannot take this LGA 1151 chip despite similar names. The Socket vs chipset: what decides whether a CPU works guide details matching.
Single socket desktops are the deployment. Growth means another LGA 1151 chip on the same board where listed. Power supplies from prior offices usually carry over.
Memory, PCIe and cooling
DDR4-2133 in two channels suits office desktops with SSD boot drives. Matched pairs help integrated graphics during video calls. Start with 4 GB for task work.
PCIe 3.0 with 16 lanes from the CPU serves board slots per LGA 1151 layout. Many builds use integrated graphics and leave the slot free. Chipset lanes add storage and USB.
Cooling uses the LGA 1151 mount from the CPU cooler compatibility by socket guide. The boxed stock cooler runs quietly. Keep filters clean where fleets run daily.
Upgrade paths
On the same socket, the Intel Celeron G3920 lifts to 2.9 GHz at the same 51 W for slightly faster desks. The Intel Pentium G4400 moves to 3.3 GHz with more cache. Both share LGA 1151 boards.
Core i3-6100 adds threads for heavier multitasking where listed.
Past LGA 1151 offices move to Kaby Lake Celeron parts. The G3900 covers 2015 desks where two basic cores must deploy at entry cost.
