Core i3-330M vs Celeron 3205U

The Core i3-330M packs 2 cores / 4 threads, matching the Celeron 3205U's 2 cores. Boost clocks reach 0.13 GHz on the Core i3-330M versus 1.5 GHz on the Celeron 3205U — a 168.1% clock advantage for the Celeron 3205U (base: 2.13 GHz vs 1.5 GHz). The Core i3-330M uses the Arrandale (2010−2011) architecture (32 nm), while the Celeron 3205U uses Broadwell-U (2015) (14 nm). In PassMark, the Core i3-330M scores 1,032 against the Celeron 3205U's 1,025 — a 0.7% lead for the Core i3-330M. Geekbench 6 single-core — the metric most relevant to gaming — records 317 vs 287, a 9.9% lead for the Core i3-330M that directly translates to higher frame rates. Multi-core Geekbench: 689 vs 483 (35.2% advantage for the Core i3-330M). L3 cache: 3 MB (total) on the Core i3-330M vs 2 MB (total) on the Celeron 3205U.

The Core i3-330M uses the PGA988 socket (PCIe 2.0), while the Celeron 3205U uses FCBGA1168 (PCIe 3.0) — making them incompatible on the same motherboard. Both support up to DDR3-1066 memory speed. The Celeron 3205U supports up to 16 GB of RAM compared to 8 GB — 66.7% more capacity for professional workloads. Both feature 2-channel memory with ECC support. Both provide 16 PCIe lanes. Chipset compatibility: HM55,PM55,QM57 (Core i3-330M) and Wildcat Point-LP (Celeron 3205U).

Neither processor supports overclocking. Virtualization support: VT-x / EPT (Core i3-330M) vs VT-x (Celeron 3205U). Both include integrated graphics — Intel HD Graphics (Arrandale) (Core i3-330M) and HD Graphics (Broadwell) (Celeron 3205U) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i3-330M targets Legacy Budget, Celeron 3205U targets Budget. Direct competitor: Core i3-330M rivals AMD Athlon II P320; Celeron 3205U rivals Pentium 2117U.
