CPU Comparison
Intel Core i3-1125G4 (IPU) vs Intel Core i3-1215U (IPU)
A side-by-side comparison of specs, performance and value. The Intel Core i3-1125G4 (IPU) is a 4-core, 8-thread Tiger Lake mobile processor featuring an integrated Image Processing Unit (IPU) 6.0, designed specifically for OEMs building laptops with advanced AI-enhanced webcam and video conferencing capabilities.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
The 4 cores provide a solid foundation for office multitasking, easily handling dozens of browser tabs alongside office applications.
Identical CPU performance to the 1215U for office tasks. The IPU may provide a subtle advantage in network-heavy productivity scenarios.
Gaming
The Iris Xe G4 graphics are better suited for video output than gaming. Only the lightest e-sports titles are playable.
Same as the standard 1215U—not designed for gaming.
Virtualization
8 threads allow for running a couple of standard VMs, but the 15W TDP limits heavy sustained virtualization workloads.
Same 8-thread limitation as the 1215U. The IPU could potentially assist with network I/O in virtualized environments.
Efficiency
The IPU 6.0 actually improves overall system efficiency by offloading video processing tasks from the CPU and GPU.
The IPU can improve efficiency by offloading I/O processing, potentially reducing P-core wake-ups during network activity.
Specialized Performance
AI / ML
- The IPU 6.0 provides dedicated AI acceleration specifically for image and video processing
