Celeron 2980U vs Core i7-620UM

The Celeron 2980U packs 2 cores / 2 threads, matching the Core i7-620UM's 2 cores. Boost clocks reach 1.6 GHz on the Celeron 2980U versus 2.13 GHz on the Core i7-620UM — a 28.4% clock advantage for the Core i7-620UM (base: 1.6 GHz vs 1.06 GHz). The Celeron 2980U uses the Haswell (2013−2015) architecture (22 nm), while the Core i7-620UM uses Arrandale (2010−2011) (32 nm). In PassMark, the Celeron 2980U scores 1,092 against the Core i7-620UM's 1,091 — a 0.1% lead for the Celeron 2980U. Geekbench 6 single-core — the metric most relevant to gaming — records 354 vs 350, a 1.1% lead for the Celeron 2980U that directly translates to higher frame rates. Multi-core Geekbench: 694 vs 700 (0.9% advantage for the Core i7-620UM). L3 cache: 2 MB (total) on the Celeron 2980U vs 4 MB (total) on the Core i7-620UM.

The Celeron 2980U uses the FCBGA1168 socket (PCIe 3.0), while the Core i7-620UM uses BGA1288 (PCIe 2.0) — making them incompatible on the same motherboard. Both support up to DDR3L-1600 memory speed. The Celeron 2980U 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. PCIe lanes: 12 (Celeron 2980U) vs 16 (Core i7-620UM) — the Core i7-620UM offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: Haswell-ULT (Celeron 2980U) and HM55,QM57 (Core i7-620UM).

Neither processor supports overclocking. Both support VT-x virtualization. Both include integrated graphics — Intel HD Graphics (Haswell) (Celeron 2980U) and Intel HD Graphics (Ironlake) (Core i7-620UM) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Celeron 2980U targets Low Power, Core i7-620UM targets Ultra-Portable Laptop. Direct competitor: Celeron 2980U rivals AMD A4-5000; Core i7-620UM rivals Core 2 Duo SU9600.
