The company says it’s enabled it on 99% of installations. Chrome desktop version 67. The remaining 1% is used for activity monitoring and error detection.
Google plans to enable Site Isolation for Chrome on Android, but hasn’t revealed which version will enable it by default. Business users can enable Site Isolation on Chrome 68 for Android, and can also be enabled manually.

Site Isolation will be activated on Chrome after you restart. You can turn off this feature using the same steps but return to the Disabled state. If you encounter any errors, turn off this feature and use it normally.
Site Isolation increases memory usage on Chrome because it requires more processes. Google’s own benchmarks also show that using Site Isolation on the desktop increases memory usage by 10 to 13%.
