What the Celeron G3950 is
The Celeron G3950 is a two core, two thread desktop processor from Kaby Lake. It launched in January 2017 with a fixed 3.0 GHz at 51 W. The fastest Celeron in the Kaby Lake set covers office towers where a high fixed dual core clock beats lower clocks with more threads for single task work.
Two megabytes of cache feed responsive desktops with a few apps open. The 3.0 GHz fixed pace leads the Celeron range for page loads and document work. Fifty one watts suit standard tower coolers.
HD Graphics 610 with 12 execution units from 350 MHz to 1050 MHz drives office monitors. The higher graphics burst over the G3930 helps 4K signs. Hardware decode keeps video smooth without a card.
On 14 nm the G3950 tops the Kaby Lake Celeron stack above the G3930. Small businesses pick it for reception PCs and terminals. ECC support on validated boards suits tiny servers.
Socket and motherboard compatibility
The G3950 fits LGA 1151 revision 1 only. Two hundred series boards accept it natively, while 100 series may need a BIOS update. Three hundred series boards never support Kaby Lake Celerons.
The Socket vs chipset: what decides whether a CPU works guide explains revision gaps. Thin boards with 35 W limits should use the T parts instead.
The Pentium Intel Pentium G4620 on the same socket adds Hyper-Threading and higher graphics for multitasking. The G3930 is the lower clock sibling where cost matters.
Memory, PCIe and cooling
DDR4-2133 or DDR3L up to 64 GB in two channels is the memory design. ECC validates where boards allow it. Dual channel pairs help the graphics block.
Sixteen PCIe 3.0 lanes support a single slot or NVMe drives. Office towers rely on integrated displays. SSD choice decides boot feel more than 100 MHz of CPU clock.
Fifty one watts cool with stock tower coolers on the 75 mm pattern shared with LGA 1155, 1150 and LGA 1200. Low dust builds last longer in shops.
Upgrade paths
On the same socket Pentium G4600 series parts add threads, while Core i3-7300 adds clocks and cache. All reuse board and DDR4. A Core i5-7400 moves to four cores where needed.
Past revision 1 a new board is required. Most fleets add SSDs before CPU changes.
