Core i3-330UM vs Celeron 5305U

The Core i3-330UM packs 2 cores / 4 threads, matching the Celeron 5305U's 2 cores. Boost clocks reach 0.1 GHz on the Core i3-330UM versus 2.3 GHz on the Celeron 5305U — a 183.3% clock advantage for the Celeron 5305U (base: 1.2 GHz vs 2.3 GHz). The Core i3-330UM uses the Arrandale (2010−2011) architecture (32 nm), while the Celeron 5305U uses Comet Lake-U (2019−2020) (14 nm). In PassMark, the Core i3-330UM scores 1,297 against the Celeron 5305U's 1,307 — a 0.8% lead for the Celeron 5305U. Geekbench 6 single-core — the metric most relevant to gaming — records 300 vs 480, a 46.2% lead for the Celeron 5305U that directly translates to higher frame rates. Multi-core Geekbench: 600 vs 865 (36.2% advantage for the Celeron 5305U). L3 cache: 3 MB on the Core i3-330UM vs 2 MB on the Celeron 5305U.

The Core i3-330UM uses the BGA1288 socket (PCIe 2.0), while the Celeron 5305U uses FCBGA1528 (PCIe 3.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR3-800 on the Core i3-330UM versus DDR4-2400 on the Celeron 5305U — the Celeron 5305U supports 28.6% faster memory, which can translate to measurable gains in memory-sensitive workloads. The Celeron 5305U supports up to 64 GB of RAM compared to 8 GB — 155.6% more capacity for professional workloads. Both feature 2-channel memory with ECC support. PCIe lanes: 16 (Core i3-330UM) vs 12 (Celeron 5305U) — the Core i3-330UM offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: HM55 (Core i3-330UM) and Comet Lake-U (Celeron 5305U).

Neither processor supports overclocking. Both support VT-x, VT-d virtualization. Both include integrated graphics — Intel HD Graphics (Core i3-330UM) and UHD Graphics (Comet Lake) (Celeron 5305U) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i3-330UM targets Legacy Laptop, Celeron 5305U targets Budget. Direct competitor: Core i3-330UM rivals Pentium SU7300; Celeron 5305U rivals Pentium Gold 6405U.
