Performance Revolution: From Good to Great
The heart of the CM5's transformation lies in its upgraded silicon. The module transitions from the Broadcom BCM2711 found in the CM4 to the more powerful BCM2712 system-on-chip (SoC). This upgrade brings a substantial performance boost, with the processor featuring a quad-core ARM Cortex-A76 architecture running at 2.4GHz—a significant jump from the CM4's 1.5GHz cores.
Performance benchmarks reveal the true extent of these improvements. The CM5 delivers 2-3x faster performance compared to its predecessor, with some specific benchmarks showing even more dramatic improvements. Storage performance particularly stands out, with read speeds reaching approximately 309 MB/s compared to the CM4's 80 MB/s—representing a 3.8x improvement, while write speeds show a 1.7x increase.
The enhanced eMMC storage system contributes significantly to overall system responsiveness. The eMMC on CM5 is considerably faster than CM4 and outperforms most microSD cards, making it particularly suitable for applications requiring consistent, reliable storage performance.
Comprehensive Configuration Options
The CM5 maintains the flexible configuration approach that made the CM4 successful while expanding the available options. The module comes with DRAM options of 2GB, 4GB, 8GB, and now 16GB, catering to a wide range of application requirements from basic embedded systems to memory-intensive industrial applications.
Storage configurations are equally diverse, with eMMC options including 16GB, 32GB, and 64GB variants, plus models without onboard storage for applications requiring external storage solutions. Pricing ranges from $45 for the 2GB model with no Wi-Fi or onboard eMMC storage, to $95 for the 8GB model with 64GB of eMMC and Wi-Fi.
Enhanced Connectivity and I/O Capabilities
Modern embedded applications demand robust connectivity, and the CM5 delivers comprehensively. The module includes Wi-Fi 5 and Bluetooth 5.0 wireless connectivity, along with a Gigabit Ethernet port supporting the IEEE 1588 protocol—a crucial feature for industrial applications requiring precise time synchronization.
The I/O capabilities have been substantially enhanced to support more demanding applications. The CM5 features dual 4Kp60 HDMI output, enabling high-resolution dual-display setups that were previously challenging to achieve with earlier Compute Modules. Expansion interfaces include two USB 3.0 ports and two MIPI DSI/CSI connectors, providing ample connectivity for cameras, displays, and other peripherals.
Network performance testing reveals impressive capabilities, with Ethernet speeds achieving stable throughput of about 936 Mbps using iPerf3 testing. This near-gigabit performance makes the CM5 suitable for network-intensive applications and industrial IoT deployments.
