Core i5-4302Y vs Celeron 4305U

The Core i5-4302Y packs 2 cores / 4 threads, matching the Celeron 4305U's 2 cores. Boost clocks reach 2.3 GHz on the Core i5-4302Y versus 2.2 GHz on the Celeron 4305U — a 4.4% clock advantage for the Core i5-4302Y (base: 1.6 GHz vs 2.2 GHz). The Core i5-4302Y uses the Haswell (2013−2015) architecture (22 nm), while the Celeron 4305U uses Whiskey Lake-U (2018−2019) (14 nm). In PassMark, the Core i5-4302Y scores 1,580 against the Celeron 4305U's 1,562 — a 1.1% lead for the Core i5-4302Y. L3 cache: 3 MB on the Core i5-4302Y vs 2 MB (total) on the Celeron 4305U.

The Core i5-4302Y uses the FCBGA1168 socket (PCIe 3.0), while the Celeron 4305U uses FCBGA1528 (PCIe 3.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR3L-1600 / LPDDR3-1600 on the Core i5-4302Y versus 2133 on the Celeron 4305U — the Celeron 4305U supports 199.4% faster memory, which can translate to measurable gains in memory-sensitive workloads. The Celeron 4305U supports up to 64 of RAM compared to 16 GB — 120% more capacity for professional workloads. Both feature 2-channel memory with ECC support. PCIe lanes: 12 (Core i5-4302Y) vs 16 (Celeron 4305U) — the Celeron 4305U offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: HM86,HM87 (Core i5-4302Y) and Whiskey Lake-U (Celeron 4305U).

Neither processor supports overclocking. Virtualization support: VT-x / VT-d / EPT (Core i5-4302Y) vs true (Celeron 4305U). Both include integrated graphics — Intel HD Graphics 4200 (Core i5-4302Y) and Intel UHD Graphics 610 (Celeron 4305U) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i5-4302Y targets Productivity, Celeron 4305U targets Budget. Direct competitor: Celeron 4305U rivals Pentium Gold 5405U.
