Performance Compared

Productivity

Intel Core i3-1005G130

Single-app use is fine, but opening multiple browser tabs alongside Office apps will cause noticeable slowdowns.

Intel Core i3-1115G4 (IPU)Best46

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.

Gaming

Intel Core i3-1005G15

The basic UHD graphics are too weak for any meaningful gaming experience.

Intel Core i3-1115G4 (IPU)Best18

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

Virtualization

Intel Core i3-1005G110

2 cores and 4 threads are barely enough for the host OS, let alone a virtual machine.

Intel Core i3-1115G4 (IPU)Best18

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

Efficiency

Intel Core i3-1005G185

Good efficiency for a 15W chip, allowing for 6-8 hours of real-world battery life in basic ultrabooks.

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.

Strengths & Weaknesses

Intel Core i3-1005G1

Pros

  • Native Thunderbolt 3 support is excellent for docking stations
  • Sunny Cove architecture provides strong single-thread performance for basic tasks
  • 15W TDP allows for slim, portable laptop designs
  • DDR4 and LPDDR4X memory flexibility
  • 10nm process was very efficient for its time

Cons

  • Only 2 cores and 4 threads, which is inexcusable at its $281 MSRP
  • Basic UHD graphics lack the power of the Iris Plus found on other Ice Lake chips
  • No PCIe 4.0 support
  • Cannot handle modern multi-tab browsing without stuttering
  • L3 cache is limited to 4 MB
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

Our Verdict on Each

The i3-1005G1 successfully brought 10nm and Thunderbolt 3 to cheap laptops, but its 2-core CPU and stripped-back graphics make it a poor choice for anything beyond light tasks.

Best for: The only scenario where an i3-1005G1 laptop makes sense is if it is being sold at an extreme clearance price (under $100) and you need a disposable machine for a child's schoolwork or a dedicated document viewer. The inclusion of Thunderbolt 3 means it can connect to high-speed docks, which might be useful for legacy office setups.

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.
