Google Chrome’s new Memory Saver mode on the desktop is receiving an upgrade that aims to make it even smarter. The feature is set to determine which open tabs it can utilize in order to reduce memory usage.
This new enhancement, known as Probabilistic Memory Saver Mode, is currently being tested in Google Chrome Canary version 121. While not enabled by default, users can access it by typing “about://flags” into the address bar.
The Memory Saver mode effectively puts inactive tabs to sleep, freeing up RAM for the active tabs. However, there is a trade-off as reactivating these inactive tabs may take some extra time.
The Probabilistic Memory Saver Mode utilizes probability distributions to estimate the likelihood of tab revisits, ultimately aiming to strike a better balance between memory saving and tab snoozing.
While Google has not made any official statements about this new feature, it appears that it will assign a probability score to each open tab based on its likelihood of being reopened, taking into account its content, frequency of revisits, and duration of inactivity.
It remains to be seen whether this feature will be rolled out to the stable version of Chrome for all users, but any improvement to the Memory Saver mode should be beneficial. The feature may undergo further tweaking and optimization based on its testing stage.
This isn’t the first upgrade given to the Memory Saver feature. In June, Google added the ability for users to view the amount of RAM each tab is using, making it easier to identify and close down tabs that are consuming excessive memory.
