COM-HPC
To fulfill the growing demand of high-performance computing and high-speed I/O interface, the PCI Industrial Computer Manufacturers Group (PICMG) has developed the new COM-HPC (High-Performance Computing) computer-on-module specification. COM-HPC uses the same concept as COM Express, but increases the connectors from 440 pins to 800 pins to support more expansions, and improves the speed of the I/O interface with PCIe Gen 4 or Gen 5 (32GT/s), USB 3.2 Gen 2x2 (20Gbps) or USB 4 (40Gbps), and 25G KR signals. COM-HPC has two module types, Server and Client. The Server type focuses on server applications, providing up to 65 lanes of PCIe, 8 KR Ethernet, and utilizes CPU with TDP of up to 150W. In contrast, the Client type provides 49 PCIe lanes and multiple media interfaces, featuring high-performance graphics, MIPI-CSI, Soundwire, I²S, etc. And it also provides high-speed networking interfaces of NBase-T and 25GbE KR signals to address the needs of various applications.
Portwell has initiated the development of COM-HPC Server and Client type modules and carriers to meet the demand of higher performance computing in applications including edge computing, 5G, IoT, AI, and much more.

| NBASE-T (Max. 10G) | 2 | 1 |
| USB 2.0 | 8 | 8 |
| *USB 3.2 | *4 | *2 |
| *USB 4 | *4 | *2 |
| DDI, eDP/MIPI-DSI | 3, 1 | 0 |
| Soundwire, I2S | 2, 1 | 0 |
| SATA | 2 | 2 |
| eSPI, SPI | 1, 2 | 1, 2 |
| SMB, I²C, IPMB | 1, 2, 1 | 1, 2, 1 |
| UART | 2 | 2 |
| GPIO | 12 | 12 |
*Note: All USB 3.2 and USB4 options are “upgrade” options: A USB 3.2 instance uses up a COM-HPC USB 2.0 port. A USB4 instance needs to use a USB 3.2 Gen 2x2 port (which in turn uses up a USB 2.0 port).
