IntelLaptop CPUTiger Lake

Intel Core i3 laptop processor on Tiger Lake, with 2 cores and 4 threads and 1280 KB L2, 6 MB L3 at 28 W TDP on a 10 nm process addressing up to 64 GB and Intel UHD Graphics for 11th Gen Intel Processors.

What you need to know

Intel Core i3-1115G4 is a aging laptop cpu.

Intel Core i3-1115G4 launched in July 1, 2020., It has 2 cores and 4 threads on Tiger Lake, dropping into the FCBGA1449 socket. Treat the spec table as the facts. Age alone does not tell you to throw it out.

Still good?: Only if the workload is light
Product age: 6 years old
Upgrade pressure: Moderate

Feex says

Laptop SKUs are power-limited. The name on the lid is not the same chip you would get on a desktop board.

What this hardware means today

Age and usefulness are not the same number. This page keeps them separate.

Performance today: Modest. Laptop performance depends on the OEM power limit as much as this SKU name.
Product age 6 years old: Aging. Launched July 1, 2020. Newer platforms exist. That does not make this chip unusable by itself.
Support status: Supported. Current Windows and current applications still run on this class of CPU. Platform BIOS support depends on the motherboard or laptop vendor.
Upgrade pressure: Moderate. Upgrade pressure comes from platform features and specific CPU-bound work, not from the chip being unusable.

Where does it sit?

Tiger Lake sits on Intel's recent Core timeline. Later desktop branding moved toward Core Ultra.

Performance context

These are qualitative readings, not a fake 8.7 out of 10. Workload still wins.

Gaming: Good

Fine when the laptop GPU is the limit. CPU names on thin laptops often are not.

Productivity: Modest

2 cores cover office, browser, and compile work in this class.

Multithreaded workloads: Average

4 threads. Heavy encodes still scale further on higher-core parts.

General use: Good

Everyday Windows use is not where most people notice this SKU first.

Efficiency: Depends on the laptop

The same SKU in two laptops can draw very different power. Read the device, not the CPU name alone.

Should you upgrade?

Probably not based on CPU performance alone.

Upgrade makes more sense if

Your workload is strongly CPU limited
You need a newer platform for memory, I/O, or chipset features
You need substantially more multicore performance
You are buying a whole new laptop anyway

Upgrade makes less sense if

The GPU is the real bottleneck
Current applications are already responsive
The CPU rarely limits your workload

Compatibility

Compatibility
Socket	FCBGA1449
Board	A shared socket is not automatic compatibility. Check the motherboard CPU list and BIOS revision.
Memory	DDR4, LPDDR4X, up to 64 GB
Graphics	Intel UHD Graphics for 11th Gen Intel Processors

A shared socket is not automatic compatibility. Boards often need a BIOS update before a newer chip in the same socket will post.

Laptop power limits, cooling, and the OEM firmware matter as much as the model name.

Read the memory list on the board. The CPU can list more standards than one motherboard will accept.

No post after a CPU swap

Clear CMOS only after you confirm the board list includes this SKU and the BIOS is new enough. A supported name on a box is not the same as a flashed board.
