7EX470.50-1 is a very important part of the new standard specification. com express is limited to 3rd generation PCIe with transfer speeds of 8 Gb per second and a clock frequency of 5.0 GHz. the new connector can support transfer speeds in excess of 32 Gb per second, which is equivalent to 5th generation PCIe. in addition, support for up to 65 PCI Express paths is sufficient to connect many powerful GPGPUs and machine learning. com express can only support a maximum of 32 PCI Express. COM Express only supports a maximum of 32 PCI Express.

The 7EX470.50-1’s performance performance is currently limited to 10 Gb Ethernet per signal pair, which will also ramp up to at least 25 Gb Ethernet per signal pair, making 100 Gb Ethernet support possible. The new generation of processors for edge computers will also require more interconnections and space for more DIMM slots. This new standard can support up to eight DIMM slots and 800 pins, compared to just 440 pins for COM Express.

The 7EX470.50-1 module has two performance classes, which, like today’s COM Express Type6 and Type7, are divided into Client and Server classes. From the outset, the design area of both types meant that large, high-end COM-HPC modules could accommodate up to eight DIMM slots. The illustration also clearly shows the same layout for different sizes of inter-board connectors.
