IntelEmbedded CPUTiger Lake

Intel Core i5 embedded processor on Tiger Lake, with 4 cores and 8 threads and 8 MB L3 at 15 W TDP on a 10 nm process addressing up to 64 GB and Intel Iris Xe Graphics.

What you need to know

Intel Core i5-1145GRE is a aging embedded cpu.

Intel Core i5-1145GRE launched in July 1, 2020., It has 4 cores and 8 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

If apps already feel slow, check RAM and storage before you blame this CPU by name alone.

What this hardware means today

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

Performance today: Average. Average for the class when RAM, storage, and the GPU keep up.
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

Playable in lighter titles. A weak GPU will hide whatever this chip still has.

Productivity: Average

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

Multithreaded workloads: Average

8 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: Good

Rated 15 W base power. That is a platform number, not a promise about your cooler.

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 need newer connectivity that your current board cannot offer

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 Iris Xe Graphics

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

Cooler clearance, VRM quality, and power limits matter as much as the socket 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.
