10th Gen Intel Core i3 1005G1 Review

The 10th Gen Intel Core i3 1005G1 is a 2-core, 4-thread processor built on Intel's Ice Lake architecture, running a 1.2 GHz base clock that boosts to 3.4 GHz within a 15 Watt TDP.

Positioned in budget and mid-range laptops, this chip's Sunny Cove core design gave it a genuine IPC advantage over the previous-generation 8th and 9th Gen Core i3 chips it replaced, despite the modest 2-core count.

Intel UHD Graphics G1

An entry-tier Gen11 integrated GPU, a real step up from the older UHD 620 found on the prior generation, though still limited to light gaming at reduced settings rather than any serious graphics workload.

How Is the Core i3 1005G1 in Terms of Performance

The 2-core, 4-thread layout limits multi-threaded ceiling compared to quad-core i3 chips of later generations, but the Sunny Cove architecture's single-thread improvements make this chip genuinely competitive for everyday tasks: browsing, office work, and media consumption.

Benchmarks

Cinebench R23 multi-core scores of 928 and single-core scores of 408 reflect the 2-core ceiling directly.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Best for

Budget and mid-range laptops focused on everyday computing: browsing, office work, media consumption

Not for

Multi-threaded workloads or multitasking-heavy use, the 2-core count is a real ceiling regardless of the strong per-core architecture
