The Ryzen™ 8040 Series processors build upon the foundation set by the previous 7040 Series, introducing several key enhancements that significantly improve performance, power efficiency, and connectivity. Based on the latest AMD technology, this series is designed to meet the demanding needs of modern applications, from enhanced multimedia capabilities to robust enterprise solutions.

Key Features of the Ryzen™ 8040 Series

1. AI Processing Power: The 8040 Series features an integrated Neural Processing Unit (NPU) on select models which offers up to 1.6 times more AI processing performance compared to the previous models. This enhancement enables larger AI model handling directly on the device, facilitating more complex and real-time AI user experiences​.

2. Processor Architecture and Performance: Built on the AMD "Zen 4" architecture, the 8040 Series processors can have up to eight cores, capable of delivering up to 16 threads of processing power. Notable models like the Ryzen 9 8945HS provide significantly enhanced performance metrics—up to 64% faster video editing and up to 37% faster 3D rendering compared to competitors. These processors also feature advanced RDNA 3 architecture-based Radeon graphics for superior gaming and creative performance​.

3. Power Efficiency and Support for Advanced Memory: The 8040 Series supports advanced LPDDR5 memory, which contributes to its ability to manage high-demand applications more efficiently while also ensuring longer battery life through innovative power management features. This is especially beneficial for ultrathin laptops where power efficiency is crucial​.

4. Enhanced Connectivity and Features: These processors are designed to leverage the full range of the Windows 11 ecosystem for optimized performance, including comprehensive support for the latest security features and AI-enhanced applications provided by Windows. Features like background blur, eye gaze tracking, and noise cancellation are now accessible out-of-the-box on systems with these processors.

5. Software Ecosystem and Developer Support: AMD has also introduced Ryzen AI 1.0 Software alongside the 8040 Series. This software stack makes it easier for developers to deploy machine learning models trained in frameworks like PyTorch or TensorFlow, which can run efficiently on these processors​.

Note: Top Side of SoM is placed on Top Side of NIO, where the two boards are flipped one towards the other.

Board-to-board Connectors Pin-out

The following is an example of the B2B pinout in NIO.
Please note that the pinout relates to the female connectors on a carrier, to which the Bedrock SoM male Connectors are inserted, and here we gave an example for SolidRun NIO Connectors (J4, J5, J6, J7). It’s important to be careful which pin is number #1.

Power Consumption

SmartShift Technology for Optimized Power Management

One of the key features of our System on Module, integrated with AMD Ryzen™ processors, is the SmartShift technology. This innovative feature allows for dynamic adjustment of power allocation between the CPU and other system components. By intelligently shifting power where it's needed most, SmartShift enhances overall performance and efficiency, making it an ideal solution for power-sensitive applications.

Controlling CPU Power Consumption

With SmartShift, you can precisely control the power consumption of the CPU, tailoring it to fit the specific needs of your application. This capability is especially beneficial in scenarios where power efficiency is crucial, such as in portable or battery-operated devices. You can set a limit to the CPU power consumption, for example, capping it at a specific wattage to balance performance with power usage.

Configuring CPU Power Limits in BIOS

To configure the CPU power limits, you can access the BIOS settings of our System on Module. We provide a detailed guide on how to navigate these settings and effectively set the desired power caps for your application.

For step-by-step instructions on accessing and modifying these settings, please visit our detailed BIOS configuration page here: Bedrock V3000 BIOS Settings - Power Screen.

By leveraging the SmartShift technology and configuring your CPU power settings via BIOS, you can optimize your system’s performance and power consumption, leading to a more efficient and tailored usage according to your specific requirements. This section of the manual ensures that you have all the necessary tools and knowledge to take full advantage of the innovative features provided by our System on Module.

To demonstrate the efficacy and benefits of the SmartShift technology in our System on Module (SoM), extensive measurements have been conducted using a SoM based on the AMD Ryzen™ 7 7840HS processor paired with the Networking & I/O extension board (NIO). These tests were aimed at validating how effectively SmartShift manages power distribution under various operational conditions.

SmartShift Configuration Parameters:

The SmartShift feature is controlled through four key parameters in the BIOS Power tab, which allow for precise management of power distribution and consumption:

• APU Only sPPT Limit: Sets the peak power limit that the Accelerated Processing Unit (APU) can consume.

• Sustained Power Limit: Defines the sustained power threshold for long-term performance stability.

• Fast PPT Limit: Regulates the rapid power allowance for short bursts of intensive processing.

• Slow PPT Limit: Controls the lower power threshold, suitable for maintaining efficiency during less demanding tasks.

Measurement Results

The following table illustrates the power consumption results (in Watts) observed under various settings of these parameters. These measurements provide clear insights into how SmartShift adjusts power usage dynamically, ensuring optimal performance and efficiency across different workloads and operational states.

The tests outlined in the table above were conducted while the system was running CineBench R23, specifically utilizing the Multi-Core test mode. This benchmarking tool is widely recognized for its ability to stress multiple CPU cores simultaneously, making it an ideal platform for evaluating the performance of the SmartShift technology under high computational loads. By conducting the tests in this environment, we ensure that the measurements accurately reflect the capabilities of SmartShift to dynamically manage and optimize power consumption during intensive processing tasks.

Power Input

The recommended input range for the SoM is 12V-24V.

SolidRun uses Molex 1053071202 Connector to interface between the SoM power input and the Phoenix Connecter.
