Intel Core Ultra X7 358H
The Intel Core Ultra X7 358H is a Panther Lake mobile processor in Intel's Core Ultra Series 3, built on the Intel 18A process. It combines 4 Performance, 8 Efficient and 4 Low Power Efficient cores (16 cores, 16 threads) with a 4.8 GHz maximum turbo and the Intel Arc B390 integrated GPU with 12 Xe cores. Intel rates it at 25 W base power and 80 W maximum turbo power.
Pros
- 16 cores and 16 threads from 4 Performance, 8 Efficient and 4 Low Power Efficient cores
- Intel Arc B390 integrated graphics with 12 Xe cores at up to 2.5 GHz
- Intel 18A manufacturing process
- NPU rated at 50 peak TOPS (Int8) for on-device AI work
- Supports up to 96 GB of LPDDR5X memory at up to 9600 MT/s
Cons
- Only 4 Performance cores, and no Hyper-Threading, so 16 cores give just 16 threads
- In review testing, multi-core results vary widely between laptops (Cinebench R23 multi from about 13,200 to 19,900 points)
- Intel lists only LPDDR5X memory for this chip (up to 96 GB), with no DDR5 option
- 80 W maximum turbo power calls for capable cooling to hold peak performance
