Intel Core Ultra 5 135U
The Intel Core Ultra 5 135U is a Meteor Lake U-series laptop processor with 12 cores and 14 threads: 2 Performance, 8 Efficient and 2 Low Power Efficient cores. It boosts up to 4.4 GHz and has a 15 W base power rating with a 57 W maximum turbo power.
Pros
- 12 cores and 14 threads from 2 Performance, 8 Efficient and 2 Low Power Efficient cores
- Up to 4.4 GHz maximum turbo frequency
- Low 15 W base power suits thin-and-light laptops
- Supports LPDDR5/X-7467 and DDR5-5600 memory, up to 96 GB
- Integrated Intel Graphics with a 1.9 GHz maximum dynamic frequency
Cons
- Only 2 Performance cores, so heavy multithreaded work leans on the Efficient cores
- 12 MB of Intel Smart Cache is modest for its core count
- Sustained speed depends on the laptop, since the 57 W maximum turbo power needs cooling headroom
