Intel Celeron G3900 2.8 GHz desktop processor

SKU CH-2W81-99TNQ

Dual-core desktop CPU running at 2.8 GHz with 2 MB cache and 51 W TDP for LGA 1151 sockets

  • CPU Socket TypeLGA 1151
  • Dual-core 2.8 GHz speed handles everyday tasks smoothly
  • LGA 1151 socket fits compatible motherboards directly
  • 51 W TDP keeps power draw and heat low
  • Intel HD Graphics 510 drives 4K display at 60 Hz

Entry-level dual-core desktop processor

The Intel Celeron G3900 runs at 2.8 GHz with two cores and two threads. It targets basic office work, web browsing and light media playback. The 51 W TDP keeps cooling requirements modest for small-form-factor builds.

LGA 1151 socket with dual-channel memory support

The processor fits motherboards with an LGA 1151 socket and drives two memory channels. Supported modules include DDR4 at 1866 or 2133 MT/s and DDR3L at 1333 or 1600 MT/s running at 1.35 V. Maximum addressable memory is 64 GB.

Integrated Intel HD Graphics 510 for sustained

The on-die GPU operates at a base frequency of 350 MHz and can reach 950 MHz under load. It reserves up to 1.7 GB of system memory and drives eDP, DisplayPort, HDMI and DVI outputs. 4K playback is supported at 60 Hz while the maximum 3D resolution is 1080p.

Perguntas sobre este artigo

What thermal limit does the 51 W TDP impose during sustained workloads?

The 51 W TDP means the cooling solution must dissipate up to 51 watts continuously; if the cooler cannot handle that heat the processor will throttle to stay within its thermal envelope.

How much fan noise and heat should I expect when the chip runs at 2.8 GHz all day?

At the 51 W TDP the CPU produces moderate heat; a standard LGA 1151 cooler keeps temperatures in check with low-to-moderate fan noise under continuous load.

Which motherboard socket and memory type do I need to have already for this processor to work?

You need a motherboard with an LGA 1151 socket and either DDR4-1866/2133 or DDR3L-1333/1600 memory running at 1.35 V.
