Celeron N2840 Details

The Intel Celeron N2840, launched in May 2014, remains a notable example of low-power mobile computing from Intel's Bay Trail-M era. While now over a decade old, its design prioritizes extreme energy efficiency, making it relevant in niche applications such as embedded systems, thin clients, or ultra-low-cost devices. As of March 2026, the processor's performance reflects its age, with benchmark results placing it near the lower end of the overall CPU hierarchy. Despite this, its low TDP of 7.5 W and compact 22 nm process node continue to make it a viable option for battery-constrained environments where raw performance is secondary to power consumption.

The Celeron N2840 is a dual-core processor with a base clock speed of 2.16 GHz and a turbo frequency of 1.86 GHz, though this is limited by the absence of simultaneous multithreading, meaning it supports only two threads. Built on the Bay Trail microarchitecture, the chip includes 512 KB of L2 cache per core and integrates Intel's HD Graphics, which operates at a base frequency of 311 MHz and can boost to 792 MHz. This integrated GPU supports up to two displays and is suitable for basic multimedia playback and light graphical tasks, though it lacks modern features like AVX-512 or advanced video encoding acceleration.

In terms of memory, the processor supports DDR3L 1333 MHz RAM with a maximum capacity of 8 GB and a peak bandwidth of 21.32 GB/s across two channels. It uses the FC-BGA1170 socket, which is common in ultra-compact notebooks and netbooks from its era. The CPU supports a broad range of instruction sets, including SSE4.1, SSE4.2, AVX, and AES-NI, though it notably lacks support for SSE4.2 in some implementations, which can hinder performance in modern applications. It also supports features like Enhanced SpeedStep Technology and Intel VT-x for virtualization, though it does not include vPro or other enterprise-grade management technologies.

Benchmarking data reveals that the Celeron N2840 achieves a single-core score of 3766, placing it at #1912 out of 2060 in the overall rankings, and a multicore score of 4400, ranking #1453. Its overall score of 4020 ranks it #1871, indicating that while it holds its own in single-threaded workloads relative to older low-power CPUs, its multicore performance is modest. The processor is outpaced by modern Celerons and even some older Atom and A-series chips in both single- and multi-threaded tasks, though it remains competitive with some early-generation Atom processors.

Given its age and modest performance, the Celeron N2840 is best suited for basic computing tasks such as web browsing, office applications, and media playback. Its low power draw and integrated graphics make it a candidate for use in low-cost, low-maintenance systems, particularly in environments where performance is not the primary concern. While it cannot compete with modern processors in terms of raw power or efficiency per watt, it still holds a place in the ecosystem of legacy and embedded systems as a reliable, energy-efficient solution.
