Intel® Celeron® N2840

The Intel Celeron N2840 is a laptop processor with 2 cores and 2 threads, built on the Bay Trail architecture. It launched in Jul 2014. Clocks run from 2.16 GHz base to 2.6 GHz boost. A 1-MB L3 cache backs the cores (1.1 MB per core). It addresses DDR3L memory up to 8 GB across 2 channels. The chip drops into the FCBGA1170 socket and exposes PCIe 2.0 (4 lanes). Rated TDP is 7.5 W. Notable platform capabilities: VT-x (Hardware Virtualization).

The Intel Celeron N2840 scores 667 in single-core performance and 581 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 623 for overall performance, 1,311 for productivity performance, 1,520 for creator performance, 541 for engineering performance and 2,146 for gaming performance. Its multi-core throughput works out to 291 per core, 291 per thread and 78 per watt. Its computed efficiency index is 227. Its performance index is 8, so its overall performance is 92% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Celeron N2840 scores 3,396 in integer math, 820 in floating-point math, 14,864 in compression, 157 in cryptography, 74 in physics simulation, 223 in vector SIMD, 3 in the prime sieve and 2,057 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 94% below in integer math, 98% below in floating-point math, 93% below in compression, 99% below in cryptography, 93% below in physics simulation, 99% below in vector SIMD, 96% below in the prime sieve and 91% below in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Celeron N2840 has 2 physical cores and runs 2 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.16 GHz and boosts up to 2.60 GHz.

The Intel Celeron N2840 is a laptop processor, belongs to the Intel Celeron family, uses the Bay Trail architecture, carries the codename Bay Trail and is manufactured on a 22 nm process. It launched in Jul 2014.

The Intel Celeron N2840 has 112 KB of L1 cache, 1 MB of L2 cache and 1 MB of L3 cache. That adds up to about 2.1 MB of cache, or 1.05 MB per core.

The Intel Celeron N2840 has a 3-level cache hierarchy: L1 at 112 KB, L2 at 1 MB and L3 at 1 MB. L2 is the largest level and makes up about 47% of the cache listed here.

The Intel Celeron N2840 supports DDR3L memory, addresses up to 8 GB of memory, uses 2 memory channels and runs memory at up to 1,333 MT/s. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Celeron N2840 includes integrated graphics (Intel HD Graphics for Intel Atom Processor Z3700 Series) and clocks the graphics up to 0.79 GHz.

The Intel Celeron N2840 uses the FCBGA1170 socket, supports PCI Express 2.0 and provides up to 4 PCIe lanes.

The Intel Celeron N2840 has a rated TDP of 8 W.
