Intel® Celeron® 3867U

The Intel Celeron 3867U is a laptop processor with 2 cores and 2 threads, built on the Kaby Lake architecture. It launched in Jan 2019. A 2-MB L3 cache backs the cores (1.4 MB per core). It addresses DDR4, LPDDR3 memory up to 32 GB across 2 channels. The chip drops into the FCBGA1356 socket and exposes PCIe 3.0 (12 lanes). Rated TDP is 15 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Celeron 3867U scores 1,058 in single-core performance and 1,396 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,215 for overall performance, 2,389 for productivity performance, 2,672 for creator performance, 1,300 for engineering performance and 3,523 for gaming performance. Its multi-core throughput works out to 698 per core, 698 per thread and 93 per watt. Its computed efficiency index is 314. Its performance index is 15, so its overall performance is 85% 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 3867U scores 3,838 in integer math, 3,304 in floating-point math, 20,409 in compression, 453 in cryptography, 153 in physics simulation, 723 in vector SIMD, 9 in the prime sieve and 2,473 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 93% below in integer math, 93% below in floating-point math, 91% below in compression, 96% below in cryptography, 86% below in physics simulation, 95% below in vector SIMD, 87% below in the prime sieve and 89% 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 3867U 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 1.80 GHz.

The Intel Celeron 3867U is a laptop processor, belongs to the Intel Celeron family, uses the Kaby Lake architecture, carries the codename Kaby Lake R and is manufactured on a 14 nm process. It launched in Jan 2019.

The Intel Celeron 3867U has 256 KB of L1 cache, 512 KB of L2 cache and 2 MB of L3 cache. That adds up to about 2.8 MB of cache, or 1.38 MB per core.

The Intel Celeron 3867U has a 3-level cache hierarchy: L1 at 256 KB, L2 at 512 KB and L3 at 2 MB. L3 is the largest level and makes up about 73% of the cache listed here.

The Intel Celeron 3867U supports DDR4, LPDDR3 memory, addresses up to 32 GB of memory and uses 2 memory channels. It does not support DDR5 memory.

The Intel Celeron 3867U includes integrated graphics (Intel HD Graphics 610) and clocks the graphics up to 0.90 GHz.

The Intel Celeron 3867U uses the FCBGA1356 socket, supports PCI Express 3.0 and provides up to 12 PCIe lanes.
