AMD Ryzen AI 9 HX PRO 370: A Hybrid Flagship for the Next-Generation Laptops

Mobile processors are experiencing a period of intense development. The competition for performance, energy efficiency, and new possibilities is unfolding in an arena where hybrid architectures and integrated AI accelerators are becoming the new standard. The AMD Ryzen AI 9 HX PRO 370 is one of the most prominent representatives of this trend. Built on the new Zen 5 microarchitecture and advanced manufacturing process, this chip is positioned as a solution for the most demanding mobile workstations and powerful laptops. Let’s look into what it actually offers.

Architecture and Manufacturing Process: Hybrid and AI in Focus

At the core of the processor is a hybrid CPU architecture from the Strix Point family. The chip is manufactured under TSMC 4nm FinFET standards, ensuring high transistor density and potentially excellent energy efficiency.

Central Processing Unit (CPU):

• Cores and Threads: A total of 12 cores and 24 threads. The architecture is hybrid: a combination of 4 performance cores (Zen 5) and 8 energy-efficient cores (Zen 5c). The former are responsible for high single-threaded performance and fast response, while the latter effectively handle parallel background and multi-threaded tasks, saving power.
• Clock Speeds: The base frequency is 2.0 GHz, with a maximum turbo frequency reaching 5.1 GHz.
• Cache Memory: The total cache volume is significant: 12 MB L2 and 24 MB L3. A large L3 cache is critically important for complex computation tasks and gaming, reducing latencies when accessing RAM.
• NPU (AI Accelerator): A key feature is the presence of the neural processing unit (NPU) based on the XDNA 2 architecture. It is designed for hardware acceleration of artificial intelligence tasks, such as noise cancellation in video chats, automatic camera framing, or local content generation.

Graphics Processing Unit (iGPU): The integrated graphics are AMD Radeon 890M. It uses RDNA 3.5 architecture and features 16 compute units (CUs) with clock speeds up to 2900 MHz. This is one of the most powerful mobile iGPUs on the market, capable of competing with entry-level discrete solutions. Support for technologies like FSR 3 and hardware AV1 encoding/decoding makes it an excellent choice for Full HD gaming and multimedia work.

Memory and Buses: The processor supports dual-channel RAM with a maximum capacity of 256 GB. It supports DDR5-5600 and LPDDR5x-8000 standards. For the expansion bus, PCIe 4.0 is utilized.

Power Consumption and Thermal Design Power (cTDP)

The nominal TDP of the processor is 28 W. This is a baseline value for high-performance thin laptops. Laptop manufacturers (OEMs) can configure long-term and short-term power limits (cTDP) over a wide range—from 15-20 W for ultra-portable devices to 45-55 W and higher in systems with robust cooling. The maximum operating temperature is 100°C.

Performance in Real-World Tasks

Performance can be gauged based on provided synthetic tests and architectural features.

• Office Work and Everyday Tasks: The processor’s power is more than sufficient. A key factor will be responsiveness, provided by the performance cores, alongside energy efficiency from Zen 5c cores and the NPU.
• Multimedia and Creativity: This is one of its strong points. The 12 cores and 24 threads demonstrate high performance in rendering, code compilation, and working with databases. Results in Geekbench 6 Multi-Core (14608) and PassMark CPU Multi-Core (32982) indicate a high level of multi-threaded performance. The integrated Radeon 890M graphics can accelerate processing for photos, videos, and 3D graphics.
• Gaming: In systems without discrete graphics, the Radeon 890M allows for comfortable play in many modern games at Full HD resolution with medium and high settings. In traditional gaming laptops, this processor will be a powerful companion for a discrete graphics card. Its high single-threaded result (~2918 in Geekbench 6 Single-Core) and multi-threaded potential will eliminate bottlenecks in CPU-dependent scenarios.
• Turbo Mode (Max Boost): Reaching a frequency of 5.1 GHz is temporary and depends on temperature, load, and system settings. In well-cooled designs, the processor will maintain high frequencies for longer durations.

Use Cases: Who Needs Such a Processor?

1. Creative Professionals on the Go: Video editors, 3D artists, designers, engineers working in demanding applications. They value multi-threading, fast memory, and powerful graphics.
2. Developers and Data Scientists: Compiling large projects, working with virtualization, local training of ML models—tasks where multi-core performance, cache size, and ECC memory support (if platform-supported) are essential.
3. Gamers Who Value Mobility: For gaming laptops without compromises, this processor will serve as an excellent foundation. For ultra-thin devices, the integrated 890M graphics will make gaming feasible.
4. Tech Enthusiasts and Early Adopters of AI: For users looking to leverage all the benefits of local AI tools on Windows, the XDNA 2 NPU will be a key advantage.

Battery Life and Energy Efficiency

The impact on battery life significantly depends on the laptop's configuration. The processor itself features energy-saving technologies:

• Hybrid Architecture: Background tasks are automatically directed to the energy-efficient Zen 5c cores.
• Hardware AI Accelerator (NPU): Performing AI tasks on a specialized block is more efficient than on the CPU or GPU.
• Support for LPDDR5x: This type of memory is more energy-efficient compared to standard DDR5.

However, in a laptop with powerful discrete graphics, a bright high-resolution display, and high-performance settings, overall battery life may be average. In configurations aimed at mobility, decent endurance for work tasks can be expected.

Comparison with Competitors

• Within the AMD Lineup: This is the flagship model in the Strix Point family. It can be compared to the previous flagship Ryzen 9 7945HX (Dragon Range) with 16 Zen 4 cores. The new model offers better energy efficiency, significantly more powerful integrated graphics, and the NPU.
• Intel Core Ultra 9 185H/285H (Meteor Lake/Arrow Lake): Direct competitors. According to synthetic tests, the Ryzen AI 9 HX PRO 370 has an advantage in multi-threading and significantly stronger integrated graphics.
• Apple M3/M3 Pro/M3 Max: A cross-platform comparison. Apple chips demonstrate phenomenal energy efficiency and performance per watt. The Ryzen AI 9 HX PRO 370 offers higher peak frequencies, support for Windows/Linux, and a wider range of specialized software for engineering tasks.
• Previous Generation (Ryzen 7040HS with Radeon 780M): The new processor is a significant step forward: a newer CPU architecture, nearly twice the performance of the iGPU, and the presence of a second-generation NPU.

Pros and Cons

Strengths:

• High multi-threaded performance (12 cores/24 threads).

3. Thin Gaming Laptops: A balance between performance and mobility, featuring discrete graphics at the level of RTX 4060/4070.

What to Look for When Buying:

• Cooling System: The more efficient it is, the more stable the performance will be.
• Type and Amount of RAM: Priority should be given to laptops with LPDDR5x-7500/8000. A minimum comfortable amount is 32 GB.
• Discrete Graphics: For maximum performance in gaming or rendering on the GPU, choose a configuration with NVIDIA GeForce RTX 4070 or higher. For portability, the iGPU 890M may suffice.
• Display: Depending on the tasks: high resolution for work, high refresh rate for gaming, good color accuracy for creativity.
