Early customers are testing the Raspberry Pi CM5 compute module.

The Raspberry Pi CM5 uses the 16nm BCM2712 processor from Broadcom, a 2.4GHz quad-core 64bit ARM Cortex-A76 CPU with 512KB per-core L2 caches and a 2MB shared L3 cache. This gives twice the performance of the previous chip in the CM4 compute module.

Details are still confidential, but the form factor is expected to be the same as the CM4 to update the performance in existing designs. However the electrical interface will be different as its supports a four lane PCI Express 2.0 interface, than the current one lane in the CM4, providing 16Gbit/s.

The additional PCIe lanes will allow more peripherals, particularly the Hailo-8 M.2 PCIe card that is being added to the Raspberry Pi 5 single board computer, multiple solid state drives for redundant RAID storage and cellular modems.

The expanded PCIe interface can also be used to add additional USB2.0 and USB3.0 interfaces.

The Raspberry Pi 5 board has a power consumption of 12W although that includes the I/O interfaces and an additional PR1 microcontroller.

Raspberry Pi has previously said it will give an update on the CM5 in the first half of 2024, which is in the next few weeks.
