Intel Core i3-1315U
Also called intel core i3-1315u, core i3-1315u, i3-1315u, core-i3-1315u
Intel Core i3 laptop processor on Raptor Lake, with 6 cores and 8 threads and 1280 KB L2, 10 MB L3 at 15 W TDP on a 10 nm process addressing up to 96 GB and Intel UHD Graphics for 13th Gen Intel Processors.
What you need to know
Intel Core i3-1315U is a previous generation laptop cpu.
Intel Core i3-1315U launched in January 1, 2023., It has 6 cores and 8 threads on Raptor Lake, dropping into the FCBGA1744 socket. Treat the spec table as the facts. Age alone does not tell you to throw it out.
- Still good?
- Yes, for lighter work
- Product age
- 3 years old
- Upgrade pressure
- Low to moderate
What this hardware means today
Age and usefulness are not the same number. This page keeps them separate.
- Performance today
- Good. Laptop performance depends on the OEM power limit as much as this SKU name.
- Product age 3 years old
- Previous generation. Launched January 1, 2023. 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
- Low to moderate. Upgrade pressure comes from platform features and specific CPU-bound work, not from the chip being unusable.
Where does it sit?
Raptor 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: Good
6 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: Excellent
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
| Socket | FCBGA1744 |
|---|---|
| Board | A shared socket is not automatic compatibility. Check the motherboard CPU list and BIOS revision. |
| Memory | DDR5, DDR4, LPDDR5, LPDDR4X, up to 96 GB |
| Graphics | Intel UHD Graphics for 13th 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.
