The fundamental design philosophies of these two processors differ significantly, reflecting AMD’s progression in chiplet technology and core layout.
- Ryzen AI 9 HX 370: This processor is based on the “Zen 5” architecture. It typically features a 12-core, 24-thread configuration. This core count is often arranged in a mix of high-performance and high-efficiency cores, a design approach that aims to balance peak power with battery life.
- Ryzen 9 7940HS: Built on the “Zen 4” architecture, this chip uses a more traditional homogeneous core design. It features 8 cores and 16 threads, all of which are high-performance cores.
The newer HX 370’s hybrid architecture can potentially offer better multi-threaded performance in heavily parallel workloads, while the 7940HS’s eight full-performance cores provide consistent power for demanding applications.
Integrated Graphics (iGPU)
Both processors include powerful integrated graphics, eliminating the need for a discrete GPU in many scenarios, but they belong to different generations of AMD’s RDNA technology.
- Ryzen AI 9 HX 370: It is equipped with the Radeon 890M integrated graphics, based on the RDNA 3.5 architecture. This iGPU generally offers a significant uplift in graphical performance and efficiency over the previous generation, making it more capable for 1080p gaming and creative applications.
- Ryzen 9 7940HS: This chip features the Radeon 780M integrated graphics, which is based on the RDNA 3 architecture. It was widely regarded as a very capable iGPU for its time and remains competent for mainstream gaming and graphical tasks.
AI and NPU Performance
This is the most defining difference between the two processors, marking a shift in how AI workloads are handled on a laptop.
- Ryzen AI 9 HX 370: The key feature of this chip is its dedicated Neural Processing Unit (NPU). This hardware accelerator is designed specifically for AI and machine learning tasks, such as video call background blur, noise cancellation, and content creation tools in creative suites. It typically offers a substantially higher TOPS (Trillions of Operations Per Second) rating for AI workloads.
- Ryzen 9 7940HS: This processor also has an AI engine, but it is an earlier-generation design with a lower TOPS performance. AI tasks on this chip are more likely to be handled by the CPU and GPU, which can be less efficient for sustained AI processing.
The HX 370 is positioned for a future where on-device AI applications become more common and demanding.
Power Efficiency and Platform Features
Being from a newer generation, the Ryzen AI 9 HX 370 often benefits from process refinements and updated platform support.
- Process Node: The HX 370 is built on a more advanced manufacturing process (typically 4nm), which can contribute to better power efficiency at similar performance levels compared to the 7940HS’s process node.
- Connectivity: Laptops featuring the HX 370 usually support newer connectivity standards like Wi-Fi 7 and may offer more modern I/O configurations, though this is also dependent on the laptop manufacturer’s design.
- Thermal Design Power (TDP): Both processors are designed for high-performance laptops and have configurable TDP ranges, generally starting around 35-54W. Actual power consumption and performance are heavily influenced by the laptop’s cooling solution and manufacturer settings.
