Intel Core Ultra 7 355

The Intel Core Ultra 5 355 is a mid-range 8-core (4+4) SoC from the Panther Lake family for notebooks.

It integrates a compute tile manufactured by Intel in the new 18A process with 4 large Cougar Cove P cores and up to 2.3 - 4.7 GHz and 4 Darkmont LP (Low Power) E cores with 1.7 - 3.5 GHz. Furthermore, the new NPU 5 with 50 TOPS INT 8 and an IPU 7.5 image processor are installed. The integrated memory controller supports up to 96 GB LPDDR5X-7467 or 128 GB DDR5-6400.

The GPU tile contains a fast iGPU with 4 Xe3 cores and ray tracing support and is manufactured by Intel in the Intel 3 process.

The third chiplet integrates the platform controller with 12 PCIe lanes, 4x Thunderbolt 4, Wi-Fi 7 (R2) and Bluetooth Core 6.0. The platform controller is also manufactured at TSMC.

The power consumption is specified from 15 W (minimum assured power) over 25 Watt (processor base power PL1) up to 55 W (maximum Turbo power).
