Celeron J3355 vs Core i3-380M

The Celeron J3355 packs 2 cores / 2 threads, matching the Core i3-380M's 2 cores. Boost clocks reach 2.5 GHz on the Celeron J3355 versus 0.53 GHz on the Core i3-380M — a 130% clock advantage for the Celeron J3355 (base: 2 GHz vs 2.53 GHz). The Celeron J3355 uses the Apollo Lake (2014−2016) architecture (14 nm), while the Core i3-380M uses Arrandale (2010−2011) (32 nm). In PassMark, the Celeron J3355 scores 1,203 against the Core i3-380M's 1,212 — a 0.7% lead for the Core i3-380M. Geekbench 6 single-core — the metric most relevant to gaming — records 450 vs 450, a 0% lead for the Core i3-380M that directly translates to higher frame rates. Multi-core Geekbench: 850 vs 1,100 (25.6% advantage for the Core i3-380M). L3 cache: 0 kB on the Celeron J3355 vs 3 MB (total) on the Core i3-380M.

The Celeron J3355 uses the FCBGA1296 socket (PCIe 3.0), while the Core i3-380M uses PGA988 (PCIe 2.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR4-2400 on the Celeron J3355 versus DDR3-1066 on the Core i3-380M — the Celeron J3355 supports 28.6% faster memory, which can translate to measurable gains in memory-sensitive workloads. Both support up to 8 GB of RAM. Both feature 2-channel memory with ECC support. PCIe lanes: 6 (Celeron J3355) vs 16 (Core i3-380M) — the Core i3-380M offers 10 more lanes for additional GPUs or NVMe drives. Chipset compatibility: N/A (SoC) (Celeron J3355) and HM55,HM57,QM57 (Core i3-380M).

Neither processor supports overclocking. Both support VT-x virtualization. Both include integrated graphics — HD Graphics 500 (Celeron J3355) and Intel HD Graphics (Gen 1) (Core i3-380M) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Celeron J3355 targets Low Power, Core i3-380M targets Legacy Laptop. Direct competitor: Celeron J3355 rivals Pentium J4205; Core i3-380M rivals AMD Athlon II P320.
