Performance Compared

Productivity

Intel Core i3-1115G4 (IPU)46

The 2 cores are adequate for light office tasks. The IPU helps keep the system responsive during video calls, but heavy multitasking will still cause slowdowns.

Intel Core i3-1120G4Best55

Good for bursty office tasks due to 4 cores, but the 1.1 GHz base clock means it drops to very low performance during sustained workloads.

Gaming

Intel Core i3-1115G4 (IPU)18

Identical to the non-IPU 1115G4. The Iris Xe G4 graphics are not viable for modern gaming.

Intel Core i3-1120G4Best20

The Iris Xe G4 graphics can handle light tasks, but the thermally constrained environment prevents sustained GPU frequencies.

Virtualization

Intel Core i3-1115G4 (IPU)18

2 cores and 4 threads are fundamentally insufficient for any practical virtualization use.

Intel Core i3-1120G4Best35

8 threads are nice on paper, but the thermal limits prevent running VMs effectively for any length of time.

Efficiency

Intel Core i3-1115G4 (IPU)85

The IPU significantly improves efficiency during its target workload (video calls), making this chip very battery-friendly for remote workers.

Intel Core i3-1120G4Best90

Extremely efficient at idle and low loads due to the 1.1 GHz base clock, perfect for always-connected devices.

Strengths & Weaknesses

Intel Core i3-1115G4 (IPU)

Pros

  • IPU 6.0 enables smooth AI video features on a budget chip
  • High 4.1 GHz boost for snappy single-task performance
  • Excellent battery life during video calls due to IPU offload
  • Low 15W configurable TDP
  • Modern 10nm SuperFin process

Cons

  • Only 2 cores and 4 threads severely bottleneck multitasking
  • 6MB L3 cache is very small
  • Only 4 CPU PCIe 4.0 lanes
  • The IPU is useless if you don't use video conferencing
  • Same price as the 4-core 1125G4 (IPU) at launch
Intel Core i3-1120G4

Pros

  • 4 cores provide good burst multi-threading
  • 1.1 GHz base enables ultra-thin, fanless designs
  • 16 PCIe 4.0 lanes for fast storage
  • Very high efficiency at low loads
  • 8MB L3 cache is generous for the segment

Cons

  • 1.1 GHz base clock causes severe performance drops under sustained load
  • BGA 1598 socket limits motherboard and upgrade options
  • No LPDDR4X support limits memory bandwidth
  • 3.5 GHz boost is the lowest among 4-core Tiger Lake parts
  • Lacks IPU 6.0 found on other similar-tier parts

    Slightly higher clocks on the same BGA 1598 platform if available.

Our Verdict on Each

A niche 2-core processor that offloads webcam AI tasks to the IPU 6.0, but the severe core count limitation makes it a poor choice for anyone doing more than light office work and video calls.

Best for: Buying a highly discounted laptop specifically for remote work and video conferencing where battery life during calls is the top priority.

Read the full review

An unusual 4-core Tiger Lake part severely limited by its 1.1 GHz base clock and BGA 1598 socket, making it a niche OEM component rather than a general-purpose mobile processor.

Best for: Purchasing a premium ultra-thin laptop or tablet where this chip is factory-installed and you value extreme portability over performance.
