Performance Compared

Productivity

Intel Core i3-1115G448

Handles word processing and spreadsheets effortlessly, but heavily multitasked office environments will expose the 2-core limitation.

Intel Core i3-1125G4Best70

Four cores handle office suites, video conferencing, and moderate multitasking with ease.

Gaming

Intel Core i3-1115G418

The Iris Xe iGPU can handle older or 2D indie games at low settings, but modern AAA titles are unplayable.

Intel Core i3-1125G4Best35

The Iris Xe GPU can handle e-sports titles like League of Legends and CS:GO at 1080p low, but it is not meant for modern AAA gaming.

Virtualization

Intel Core i3-1115G420

2 cores and 4 threads are insufficient for running anything beyond a single, very lightweight virtual machine.

Intel Core i3-1125G4Best40

Can run a single lightweight virtual machine or Docker containers, but 8 threads limit heavy virtualization.

Efficiency

Intel Core i3-1115G482

The configurable 12W-28W TDP range allows OEMs to tune it for excellent battery life in thin chassis designs.

Intel Core i3-1125G4Best88

Excellent power efficiency when paired with LPDDR4X memory, allowing for long battery life in ultrabooks.

Intel Core i3-1125G4

Our Verdict on Each

A capable entry-level mobile processor for basic tasks, hindered by its 2-core limit but benefiting from strong single-core speeds and a modern iGPU architecture.

Best for: Purchasing a highly discounted budget laptop for basic school or office work where no heavy multitasking is required.

Read the full review

The i3-1125G4 was an excellent mainstream mobile processor in 2021, bringing 4 cores and 8 threads to the i3 laptop tier alongside a significant iGPU upgrade, though it has since been surpassed by 12th-gen parts.

Best for: You should only consider buying a laptop with the i3-1125G4 today if it is being offered at a significant, heavily discounted clearance price. At launch, it was a fantastic chip for students and office workers, offering enough power for daily tasks and capable integrated graphics. However, as an end-of-life product, paying standard retail pricing for it is unwise. The newer 12th-generation i3-1215U offers hybrid P-cores and E-cores for similar money, providing much better performance and longevity. If you find a used 1125G4 laptop incredibly cheap, it remains a perfectly viable machine for web browsing and document editing.
