Performance Compared

Productivity

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.

Intel Core i3-1215U (IPU)

Identical CPU performance to the 1215U for office tasks. The IPU may provide a subtle advantage in network-heavy productivity scenarios.

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.

Intel Core i3-1215U (IPU)

Same as the standard 1215U—not designed for gaming.

Virtualization

Intel Core i3-1125G4 (IPU)45

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

Intel Core i3-1215U (IPU)

Same 8-thread limitation as the 1215U. The IPU could potentially assist with network I/O in virtualized environments.

Efficiency

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.

Intel Core i3-1215U (IPU)

The IPU can improve efficiency by offloading I/O processing, potentially reducing P-core wake-ups during network activity.
