AMD Ryzen AI 9 HX PRO 370 socket: FP8

What the Ryzen AI 9 HX PRO 370 is

The Ryzen AI 9 HX PRO 370 is the second 12-core business SKU in the Ryzen AI PRO 300 stack, sitting just under the PRO 375. Four full-size Zen 5 cores and eight compact Zen 5c cores give 24 threads at 2.0 GHz base, with the fast cores boosting to 5.1 GHz and the compact cores to 3.3 GHz. Cache totals 12 MB of L2 plus 24 MB of L3. The chip is built on TSMC 4 nm as a single monolithic Strix Point die, and its default TDP is 28 W inside a 15 to 54 W configurable range.

Graphics match the flagship part: 16 RDNA 3.5 compute units as Radeon 890M at up to 2900 MHz. Everyday office work, video calls and GPU assisted creation tasks run on the integrated GPU, and most business chassis ship without a discrete card. The XDNA 2 NPU reaches up to 50 TOPS, with combined platform throughput up to 80 TOPS. Local AI assistance, background effects and transcription run on the NPU instead of draining the battery through the CPU.

Against the PRO 375 above it, the PRO 370 keeps the same core count, clocks, cache size and graphics size, and the entire gap is 5 TOPS of NPU rating plus 5 TOPS of platform total. Fleet buyers will never notice that gap in office work, which is why the 370 is the volume 12-core for managed deployments. Both chips carry AMD PRO Technologies for remote management and hardware backed security, and both reached business channels in the January 2025 window.

Socket and motherboard compatibility

The chip solders into FP8, the 25 × 40 mm BGA that carries recent AMD mobile generations, so it cannot be removed or swapped after manufacture. Buyers choose a complete laptop with fixed processor, memory and cooling, and service means board replacement. There is no socket lever, no retention bracket and no secondhand upgrade market for the processor itself. The LGA, PGA and BGA: CPU package types explained guide explains how soldered packages differ from socketed ones.

Corporate designs from HP, Lenovo and Dell carried the PRO 300 stack through 2025 in their business lines. Firmware, drivers and management console support come from the laptop maker and the IT image, so the support page for the exact laptop model is the reference that matters. A board fault means a board swap under the service plan, never a processor swap.

Memory, PCIe and cooling

Systems pair the PRO 370 with DDR5 SODIMM modules or soldered LPDDR5X, over two channels to 256 GB. DDR5-5600 is the fastest socketed speed AMD lists, while soldered LPDDR5X reaches 8000 MT/s for extra graphics bandwidth. ECC works where the platform supports it, which suits reliability sensitive office work. Soldered memory sizes freeze at purchase, and Copilot+ features need 16 GB or more in the system.

Expansion comes from 16 usable PCIe Gen4 lanes for NVMe storage and add-on devices, with boot and RAID0 and RAID1 modes supported for the boot drive. Two native USB4 ports and three USB 3.2 Gen 2 ports come from the SoC, and display outputs drive up to four monitors. Docking stations over USB4 give most office desks their extra screens and wired networking without opening the chassis.

Cooling spans 15 to 54 W around the 28 W default and belongs to the laptop maker, with heat pipes and fans drawn for the configured TDP of each model. Boost behavior tracks power and temperature on each machine, so the same APU scores differently in a thin ultrabook and a thicker performance chassis. Long compiles and renders settle where the chassis allows, which buyers should check in reviews of the exact laptop.

Upgrade paths

Soldered laptop silicon cannot be upgraded, so buyers pick the core count, graphics size and memory at purchase and judge used machines on battery health, panel quality and chassis condition. The PRO 370 suits buyers who want twelve cores for heavy multitasking and future headroom inside a managed fleet. Buyers who run lighter office loads can step to an 8-core PRO part at the same 28 W envelope and keep the same management story.

The gap to the PRO 375 is NPU rating alone, so price and availability should decide between the two 12-core PRO parts. Against consumer Strix Point silicon, the PRO badge adds fleet management and security features that only IT departments use. A home buyer with one machine gains nothing from PRO and should compare complete laptops on display, keyboard, battery and service options instead.
