The Canon PowerShot G7 X Mark III is a 20.1MP compact camera that features a single memory card slot compatible with SD/SDHC/SDXC (UHS-I) memory cards. Faster UHS-II cards will work but only at UHS-I speeds in camera.
SD cards support capacities of between 1-2GB, SDHC cards support 2-32GB and SDXC cards support 64GB-2TB.
The Canon G7X III can shoot 4K video at 120Mbps, which is about 15MB/s. You will need a memory card with at least a V30 rating to be compatible with the video bitrates supported by the G7 X III.
Despite no in-camera speed benefit when using UHS-II cards, you will benefit when copying images back to your computer with UHS-II cards being approximately 2x faster than UHS-I cards providing a UHS-II card reader is used.

FAQs
What is the difference between UHS-I and UHS-II memory cards?
UHS-II offers much faster speeds (up to 312 MB/s) compared to UHS-I (up to 104 MB/s). This is possible via a second row of pins and two data lanes for simultaneous upstream and downstream data transfer. The extra row of pins are visible on the back of UHS-II cards. Both card types are backward compatible, but a UHS-II card will only operate at UHS-I speeds in a camera that only supports UHS-I cards.
