Intel Core Ultra X9 388H

Intel Ultra X9 388H

The Intel Core Ultra X9 388H is a fast high-end 16-core SoC of the Panther Lake family and top model with 12 Xe3 GPU cores. Furthermore, the SoC includes 18 MB Cache and support for vPro managment features (vPro eligibility).

The 388H integrates a compute tile manufactured by Intel in the new 18A (1.8nm) process with 4 large Cougar Cove P-cores clocked at up to 5.1 GHz, 8 Darkmont E-cores and another 4 Darkmont LP (low power) E-cores. Furthermore, the new NPU 5 with 50 TOPS INT 8 and an IPU 7.5 image processor are included.

The GPU tile contains a big and fast iGPU with 12 Xe3 cores and ray tracing support clocked at up to 2.5 GHz that can rival entry level dedicated GPUs.

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

The power consumption is specified from 15 W (minimum assured power) over 25 Watt (processor base power PL1) up to 80 W (maximum Turbo power).
