Chrome has always had a problem with RAM and those machines with lower specs tend to suffer, if the users runs more than half a dozen tabs. However, an upcoming update is touted to greatly lower its footprint.
This average reduction in RAM usage has been observed on a number of major websites, including Facebook, Reddit and YouTube as well as news outlets like The New York Times and The Washington Post.
Google has promised that more improvements will be made to address Google Chrome's memory consumption, with a focus on low-power devices with between 512MB and 1GB of RAM. This work will be done "over the next few months".
