Celeron J3355 vs Core i5-430M

The Celeron J3355 packs 2 cores / 2 threads, matching the Core i5-430M's 2 cores. Boost clocks reach 2.5 GHz on the Celeron J3355 versus 2.53 GHz on the Core i5-430M — a 1.2% clock advantage for the Core i5-430M (base: 2 GHz vs 2.26 GHz). The Celeron J3355 uses the Apollo Lake (2014−2016) architecture (14 nm), while the Core i5-430M uses Arrandale (2010−2011) (32 nm). In PassMark, the Celeron J3355 scores 1,203 against the Core i5-430M's 1,210 — a 0.6% lead for the Core i5-430M. Geekbench 6 single-core — the metric most relevant to gaming — records 450 vs 350, a 25% lead for the Celeron J3355 that directly translates to higher frame rates. Multi-core Geekbench: 850 vs 750 (12.5% advantage for the Celeron J3355). L3 cache: 0 kB on the Celeron J3355 vs 3 MB (total) on the Core i5-430M.

The Celeron J3355 uses the FCBGA1296 socket (PCIe 3.0), while the Core i5-430M 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 i5-430M — 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 i5-430M) — the Core i5-430M offers 10 more lanes for additional GPUs or NVMe drives. Chipset compatibility: N/A (SoC) (Celeron J3355) and HM55 (Core i5-430M).

Neither processor supports overclocking. Virtualization support: VT-x (Celeron J3355) vs VT-x, VT-d, EPT (Core i5-430M). Both include integrated graphics — HD Graphics 500 (Celeron J3355) and Intel HD Graphics (Core i5-430M) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Celeron J3355 targets Low Power, Core i5-430M targets Performance Laptop. Direct competitor: Celeron J3355 rivals Pentium J4205; Core i5-430M rivals AMD Turion II M620.
