CPU Comparison
Intel Core i3-1125G4 (IPU) vs Intel Core i3-1215U
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.
Handles standard office applications and web browsing smoothly. Heavier multitasking with many browser tabs and applications can show some slowdown.
Gaming
The Iris Xe G4 graphics are better suited for video output than gaming. Only the lightest e-sports titles are playable.
Not designed for gaming. The UHD 64EU can handle very light casual titles but modern AAA games are unplayable.
Virtualization
8 threads allow for running a couple of standard VMs, but the 15W TDP limits heavy sustained virtualization workloads.
8 threads allow for a lightweight VM alongside host tasks, but this is not a virtualization-focused part.
Efficiency
The IPU 6.0 actually improves overall system efficiency by offloading video processing tasks from the CPU and GPU.
The 15W base TDP with Intel's Thread Director scheduler enables efficient power distribution between P and E cores.
Specialized Performance
AI / ML
