The Compute Module is a Raspberry Pi 3 in a more flexible form factor, intended for industrial application. CM3L (Compute Module 3 Lite) is the Raspberry Pi 3-based revision of the original Compute Module, with a power quad-core processor. The Lite version does not come with the 4GB of on-module eMMC flash found on the standard Compute Module 3. It also does not contain the WiFi/Bluetooth chipset that comes with the Pi 3.
