A side-by-side comparison of specs, performance and value. The Intel Core i3-1115G4 is a 2-core, 4-thread mobile processor from the Tiger Lake generation, featuring high clock speeds and Iris Xe-LP integrated graphics tailored for thin-and-light laptops and everyday computing.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles word processing and spreadsheets effortlessly, but heavily multitasked office environments will expose the 2-core limitation.
Four cores handle office suites, video conferencing, and moderate multitasking with ease.
Gaming
The Iris Xe iGPU can handle older or 2D indie games at low settings, but modern AAA titles are unplayable.
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
2 cores and 4 threads are insufficient for running anything beyond a single, very lightweight virtual machine.
Can run a single lightweight virtual machine or Docker containers, but 8 threads limit heavy virtualization.
Efficiency
The configurable 12W-28W TDP range allows OEMs to tune it for excellent battery life in thin chassis designs.
Excellent power efficiency when paired with LPDDR4X memory, allowing for long battery life in ultrabooks.

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 reviewThe 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.
