Intel Celeron G1850 socket: LGA 1150

What the Celeron G1850 is

The Celeron G1850 is the fastest Haswell Celeron for LGA 1150 desktops on LGA 1150. Intel set two cores and two threads at 2.9 GHz with 2 MB of cache. Power is 53 W on 22 nm from May 2014. It leads the G1840 by 100 MHz while sharing the same board and cooler needs.

A 100 MHz step is small on paper but helps single thread office apps that never use turbo. Document work, browser tabs and terminal sessions feel slightly quicker. Two cores still bound heavy multitasking, so an SSD matters more than clocks for system feel. The chip fits schools, kiosks and home office towers where price rules.

Intel HD Graphics for 4th Generation processors runs from 350 MHz to 1.05 GHz for office monitors. DDR3-1333 and DDR3L-1333 across two channels to 32 GB feed the part. ECC works with business chipsets for always on use. It is a basic socketed Haswell with low running costs.

Socket and motherboard compatibility

The G1850 drops into LGA 1150 on 8 series boards such as H81, B85, H87 and Z87, and on 9 series boards such as H97 and Z97. Haswell runs native on both series, so most boards start without a BIOS change. Maker CPU lists still deserve a check for OEM boards with old firmware.

The 75 mm cooler square is shared with nearby LGA sockets, so cooler choice is wide. The CPU cooler compatibility by socket guide shows fit. Boards for LGA 1155 or LGA 1151 never accept this chip. The Socket vs chipset: what decides whether a CPU works guide covers series differences.

H81 remains the value match with two memory slots and a single graphics slot. B85 adds ports for small fleets. Either runs the G1850 at full speed.

Memory, PCIe and cooling

DDR3-1333 and DDR3L-1333 in dual channel to 32 GB is the memory target. Eight gigabytes covers office images with security tools. Matched pairs lift integrated graphics in meetings. ECC DIMMs work only where board and chipset support them.

Sixteen PCIe 3.0 lanes from the CPU serve one slot for graphics or add in cards. Most G1850 systems keep integrated video and use slots for capture, serial or network needs. The chipset adds PCIe 2.0 lanes for SATA and USB growth.

Stock cooling for 53 W in boxed kits handles 2.9 GHz in towers with normal airflow. Slim cases need a low profile unit with clear exhaust. The 37.5 × 37.5 mm package leaves room for standard push pin mounts.

Upgrade paths

On the same socket the Intel Pentium G3440 at 3.3 GHz with 3 MB of cache adds clocks and cache on identical boards. The Intel Core i3-4160 at 3.6 GHz with four threads adds Hyper-Threading for office multitasking. Both reuse DDR3, so board support is the only check.

A jump to DDR4 needs a new socket, board and memory. The G1850 holds entry desks where 2.9 GHz dual core work is enough.
