AMD Ryzen AI 9 HX 375 vs AMD Ryzen AI 9 HX 370: Full Comparison
Introduction
AMD’s Ryzen AI 9 HX-series processors represent a significant step in integrating dedicated neural processing units (NPUs) into mobile computing. The HX 375 and HX 370 are two flagship models in this lineup, often featured in premium laptops. This comparison aims to clarify their specifications, architectural similarities, and performance distinctions to help understand which chip might be found in different types of high-end devices. We will examine their CPU, GPU, NPU, and platform features in detail.
Architecture and Manufacturing
Both processors are built on the same foundational technology, which is a key point of similarity.
- Process Node: Both the Ryzen AI 9 HX 375 and HX 370 are fabricated on TSMC’s 4nm process, which typically contributes to power efficiency.
- Core Architecture (Zen 5): They utilize AMD’s latest Zen 5 CPU cores, which generally offer architectural improvements in instructions per cycle (IPC) over the previous generation.
- Platform: Both chips belong to the “Strix Point” family and use the FP8 socket, ensuring compatibility with a similar range of laptop designs.
There is no architectural difference in their manufacturing or core design philosophy; the divergence is in the configuration of these components.
CPU Performance and Core Configuration
This is the most significant differentiator between the two models. The core count directly influences multi-threaded performance.
- AMD Ryzen AI 9 HX 375: This chip is configured with 12 CPU cores and 24 threads. It typically features a higher maximum boost clock speed, often up to 5.1 GHz, which can benefit single-threaded tasks.
- AMD Ryzen AI 9 HX 370: This model is configured with 10 CPU cores and 20 threads. Its maximum boost clock is generally slightly lower than the HX 375’s.
The additional two cores on the HX 375 can provide a noticeable advantage in heavily parallelized applications like video rendering, code compilation, or scientific simulations. For everyday tasks and gaming, the difference may be less pronounced.
Integrated Graphics (iGPU) and AI Processing (NPU)
Both processors share identical graphics and AI acceleration hardware, making them equally capable in these domains.
- Radeon 890M Graphics: Both chips integrate the same RDNA 3.5-based graphics solution with 16 Compute Units (CUs). This iGPU is considered one of the most powerful available in a mobile processor and can handle 1080p gaming and creative workloads.
- Neural Processing Unit (NPU): A central feature of this series, both the HX 375 and HX 370 include an NPU rated at 50 TOPS (Trillions of Operations Per Second). This dedicated hardware accelerates AI tasks in applications like Windows Studio Effects, AI-powered creative software, and local large language model (LLM) inference.
For users whose workflow emphasizes graphics performance or on-device AI acceleration, there is typically no functional difference between these two processors.
Platform Features and Power
The surrounding platform capabilities and power management are consistent across both models.
- Thermal Design Power (TDP): Both processors have a configurable TDP range, often starting from 28W and going up to 54W or higher in high-performance laptop designs. The actual sustained performance will depend heavily on the laptop’s cooling solution.
- Memory Support: They support the same memory types, including LPDDR5x-7500, which is crucial for feeding data to the high-performance CPU, GPU, and NPU.
- Connectivity: Features like PCIe 4.0 support and modern wireless connectivity standards are typically equivalent between the two.

Frequently Asked Questions (FAQ)
What is the main difference between the Ryzen AI 9 HX 375 and HX 370?
The main difference is the CPU core count. The HX 375 has 12 cores and 24 threads, while the HX 370 has 10 cores and 20 threads. Their integrated graphics (Radeon 890M) and NPU (50 TOPS) are identical.
Which processor is better for AI tasks?
For dedicated NPU-driven AI tasks, they are equal, as both feature the same 50 TOPS NPU. The performance in AI workloads that also leverage the CPU or GPU might see a minor advantage for the HX 375 due to its higher core count.
Does the Ryzen AI 9 HX 375 offer better gaming performance?
Not necessarily from the graphics side, as both have the same Radeon 890M iGPU. Some CPU-bound games or scenarios might benefit slightly from the HX 375’s higher core count and boost clocks, but the difference is often marginal and depends heavily on the laptop’s thermal design.
Will I notice a difference in battery life between laptops with these chips?
Battery life is influenced more by the laptop’s design, battery capacity, display, and workload than by the choice between these two specific CPUs. Since they are on the same process node and have similar power management, battery life in comparable laptop models is typically very similar.
Final Thoughts
The AMD Ryzen AI 9 HX 375 and HX 370 are closely related processors that share their most forward-looking features: a powerful integrated GPU and a high-performance NPU. The choice between them often comes down to the specific performance tier a laptop manufacturer is targeting. The HX 375, with its 12-core design, is generally positioned for the absolute peak of mobile CPU performance within the series, potentially found in larger creator-focused or gaming laptops with robust cooling. The HX 370 offers a very similar experience for premium thin-and-light devices where the balance of performance, power, and thermal efficiency is critical. Understanding your primary workload—whether it demands maximum multi-core throughput or values the consolidated AI and graphics power common to both—can help in evaluating which chip might be present in a laptop that meets your needs.
