Performance Compared

Productivity

Intel Core i3-1115G448

Handles word processing and spreadsheets effortlessly, but heavily multitasked office environments will expose the 2-core limitation.

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 i3-1115G418

The Iris Xe iGPU can handle older or 2D indie games at low settings, but modern AAA titles are unplayable.

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 i3-1115G420

2 cores and 4 threads are insufficient for running anything beyond a single, very lightweight virtual machine.

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 i3-1115G482

The configurable 12W-28W TDP range allows OEMs to tune it for excellent battery life in thin chassis designs.

Intel Core i3-1120G4Best90

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

Our Verdict on Each

A capable entry-level mobile processor for basic tasks, hindered by its 2-core limit but benefiting from strong single-core speeds and a modern iGPU architecture.

Best for: Purchasing a highly discounted budget laptop for basic school or office work where no heavy multitasking is required.

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.
