Intel Core Ultra X9 388H

Intel Ultra X9 388H

De Intel Core Ultra X9 388H is een high-end 16-core SoC uit de Panther Lake familie en topmodel met 12 Xe3 GPU-kernen. De chip biedt ook 18 MB cache. De CPU ondersteunt vPro beheerfuncties.

De 388H integreert een compute tile die door Intel in het nieuwe 18A-proces is gefabriceerd. Deze bevat 4 grote Cougar Cove P-Cores met 2,1 - 5,1 GHz, 8 Darkmont E-Cores met 1,6 - 4 GHz en nog eens 4 kleine Darkmont LP (Low Power) E-Cores met 1,6 - 3,7 GHz. De nieuwe NPU 5 met 50 TOPS INT 8 en een IPU 7.5 beeldprocessor zijn ook geïnstalleerd. De geïntegreerde geheugencontroller ondersteunt tot 96 GB LPDDR5X-9600.

De GPU-tegel bevat een snelle iGPU met 12 Xe3-kernen en ondersteuning voor ray tracing en is vervaardigd door TSMC in het N3E-proces.

De derde chiplet bevat de platformcontroller met 12 PCIe lanes, 4x Thunderbolt 4, Wi-Fi 7 (R2) en Bluetooth Core 6.0. De platformcontroller wordt ook door TSMC gemaakt.

Volgens Intel is de TDP gespecificeerd van 15 - 25 watt (basis) en op korte termijn tot 80 watt.
