Performance Compared

Productivity

Intel Core i3-1125G4Best70

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

Intel Core i3-1125G4 (IPU)68

The 4 cores provide a solid foundation for office multitasking, easily handling dozens of browser tabs alongside office applications.

Gaming

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.

Intel Core i3-1125G4 (IPU)22

The Iris Xe G4 graphics are better suited for video output than gaming. Only the lightest e-sports titles are playable.

Virtualization

Intel Core i3-1125G440

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

Intel Core i3-1125G4 (IPU)Best45

8 threads allow for running a couple of standard VMs, but the 15W TDP limits heavy sustained virtualization workloads.

Efficiency

Intel Core i3-1125G4Best88

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

Intel Core i3-1125G4 (IPU)80

The IPU 6.0 actually improves overall system efficiency by offloading video processing tasks from the CPU and GPU.

Our Verdict on Each

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.
