Celeron 5305U vs Core i5-460M

The Celeron 5305U packs 2 cores / 2 threads, matching the Core i5-460M's 2 cores. Boost clocks reach 2.3 GHz on the Celeron 5305U versus 2.8 GHz on the Core i5-460M — a 19.6% clock advantage for the Core i5-460M (base: 2.3 GHz vs 2.53 GHz). The Celeron 5305U uses the Comet Lake-U (2019−2020) architecture (14 nm), while the Core i5-460M uses Arrandale (2010−2011) (32 nm). In PassMark, the Celeron 5305U scores 1,307 against the Core i5-460M's 1,321 — a 1.1% lead for the Core i5-460M. Geekbench 6 single-core — the metric most relevant to gaming — records 480 vs 343, a 33.3% lead for the Celeron 5305U that directly translates to higher frame rates. L3 cache: 2 MB on the Celeron 5305U vs 3 MB (total) on the Core i5-460M.

The Celeron 5305U uses the FCBGA1528 socket (PCIe 3.0), while the Core i5-460M uses PGA988 (PCIe 2.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR4-2400 on the Celeron 5305U versus 1066 on the Core i5-460M — the Core i5-460M supports 198.5% 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 — 155.6% more capacity for professional workloads. Both feature 2-channel memory with ECC support. PCIe lanes: 12 (Celeron 5305U) vs 16 (Core i5-460M) — the Core i5-460M offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: Comet Lake-U (Celeron 5305U) and HM55,HM57,QM57 (Core i5-460M).

Neither processor supports overclocking. Virtualization support: VT-x, VT-d (Celeron 5305U) vs true (Core i5-460M). Both include integrated graphics — UHD Graphics (Comet Lake) (Celeron 5305U) and Intel HD Graphics (Ironlake) (Core i5-460M) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Celeron 5305U targets Budget. Direct competitor: Celeron 5305U rivals Pentium Gold 6405U; Core i5-460M rivals AMD Turion II M620.
