AMD Ryzen AI 9 HX 370 vs AMD Ryzen AI 5 340: Full Comparison
Introduction
AMD’s Ryzen AI 300 Series processors represent a significant step in bringing dedicated Neural Processing Unit (NPU) AI acceleration to laptops. Within this series, the Ryzen AI 9 HX 370 and Ryzen AI 5 340 cater to different segments of the market. This comparison breaks down their specifications and performance characteristics to help clarify which processor might align with different user needs, focusing on technical differences rather than commercial recommendations.
Architecture and Core Configuration
Both chips are built on AMD’s latest “Zen 5” CPU architecture and “RDNA 3.5” GPU architecture, but they differ significantly in scale.
- Ryzen AI 9 HX 370: This is a 12-core processor. It typically uses a configuration of 8 high-performance “Zen 5” cores and 4 efficiency-optimized “Zen 5c” cores, for a total of 12 cores and 24 threads. This hybrid design aims to balance peak performance with power efficiency.
- Ryzen AI 5 340: This model is a 6-core processor. Its configuration generally includes 4 “Zen 5” cores and 2 “Zen 5c” cores, resulting in 6 cores and 12 threads. This makes it suitable for mainstream multitasking and applications that don’t require extreme multi-threading.
The core count difference is the most fundamental distinction, directly influencing multi-threaded performance in applications like video rendering, code compilation, and complex data processing.
Clock Speeds and Performance
Clock speeds further differentiate the performance tiers of these processors.
- Ryzen AI 9 HX 370: It operates at higher base and boost clock speeds. For example, its boost clock can reach up to 5.1 GHz or higher, allowing single-threaded tasks and gaming to benefit from faster instantaneous performance.
- Ryzen AI 5 340: This chip runs at more modest clock speeds, with a maximum boost clock typically around 4.5 GHz. This is sufficient for general productivity, web browsing, and office applications.
In workloads that leverage high single-core speeds, such as some games and legacy applications, the HX 370 generally holds an advantage. The performance gap widens in heavily multi-threaded scenarios due to its doubled core count.
Integrated Graphics (iGPU)
The integrated GPU is a key component for systems without a discrete graphics card.
- Ryzen AI 9 HX 370: It features the more powerful Radeon 890M integrated graphics. This GPU has 16 Compute Units (CUs) based on the RDNA 3.5 architecture, offering performance that can handle 1080p gaming at medium to high settings in many titles and accelerate creative workflows.
- Ryzen AI 5 340: It is equipped with the Radeon 860M integrated graphics. This GPU has 8 CUs, providing capable performance for everyday graphics tasks, light photo editing, and casual gaming, but it is less powerful than the 890M.
The choice here impacts gaming potential and graphics-heavy application performance on laptops that rely solely on the integrated GPU.
AI and NPU Performance
Both processors feature a dedicated Neural Processing Unit (NPU) for on-device AI acceleration, but they are not identical.
- Ryzen AI 9 HX 370: Its NPU is rated for approximately 50 TOPS (Trillion Operations Per Second) of AI performance. This higher throughput can benefit more demanding, sustained AI inference tasks, such as real-time video effects, advanced language models, and complex creative filters.
- Ryzen AI 5 340: Its NPU delivers around 16 TOPS of AI performance. This is still significant and capable of handling common AI-enhanced features like background blur, noise cancellation, and basic content creation assists efficiently.
While both support the current generation of Windows AI features, the HX 370’s more powerful NPU may offer better responsiveness and capability for future, more intensive AI applications.
Power and Thermal Design
The intended usage scenarios influence the thermal design power (TDP) of these chips.
- Ryzen AI 9 HX 370: As a high-performance “HX”-series chip, it is designed for more robust cooling systems found in premium thin-and-light laptops and gaming laptops. It can sustain higher power levels for extended periods to maximize performance.
- Ryzen AI 5 340: This processor is designed for standard thin-and-light and mainstream laptops. It typically operates within a lower power envelope, which can contribute to longer battery life and allows for thinner, fanless, or quieter laptop designs.
Consequently, laptops built around the HX 370 may be slightly thicker or have more active cooling, while those with the 340 can prioritize portability and silent operation.
