What the Celeron N2840 is

The Celeron N2840 tops Bay Trail-M dual cores on BGA 1170 for responsive value notebooks. It runs 2 cores and 2 threads at 2.16 GHz base with bursts to 2.58 GHz. One megabyte of L2 cache covers office apps. Power is 7.5 W with a 4.5 W SDP rating on 22 nm from late 2014.

The 2.58 GHz burst leads Bay Trail-M dual cores in single thread response. HD Graphics for Atom Z3700 series from 311 MHz to 792 MHz plays video smoothly. The 7.5 W envelope fits the same thin bodies as slower duals. The soldered package means screen and SSD decide alongside silicon.

DDR3L-1333 over two channels to 8 GB feeds cores and graphics. The N2840 covers refresh family notebooks where top dual core bursts must stay cheap.

Socket and motherboard compatibility

The N2840 solders to BGA 1170 with 7.5 W cooling. No swap exists. Refresh bodies pair it with larger SSDs. Soldered memory locks configs at purchase.

SoC SATA, USB 3.0 and PCIe serve peripherals. The LGA, PGA and BGA: CPU package types explained guide explains soldered limits.

Memory, PCIe and cooling

DDR3L-1333 over two channels to 8 GB with up to 21.3 GB/s suits family multitasking. Paired modules lift HD Graphics calls. Eight gigabytes with an SSD covers school work.

PCIe 2.0 with 4 lanes in one x4 port serves Wi-Fi and SSDs. A SATA SSD matches the power budget. Most builds stay integrated.

Cooling is a small fan for 7.5 W. Bursts to 2.58 GHz need ventilation. The 4.5 W SDP rating guides fanless leaning designs.

Upgrade paths

On the same socket, the Intel Celeron N2830 at lower bursts below saves cost, while the Intel Celeron N2930 at four cores above doubles threads. All share BGA-1170.

Braswell parts cover newer value duty. The N2840 remains the Bay Trail-M dual burst lead.
