Profile Guided Optimization is a compiler optimization technique where the most performance-critical parts of the code can run faster. The latter, however, is coming to the Beta channel, meaning it’s not yet ready. You can expect two types of speed gains: Profile Guided Optimization, which delivers up to 10% faster page loads, and Tab Throttling, which helps reduce the impact of idle background tabs. Google is promising under-the-hood performance improvements with Chrome 85.
Other browsers already have this, so here Chrome is just playing catch-up. In a future release, you’ll be able to hover over a tab and see a thumbnail preview of the page. The suggestion to switch to that tab works just like in Chrome on desktop. When you start typing a page title into the address bar on Chrome for Android, there is now an option to switch to a tab that you already have open. The new look is coming to Chromebooks first - Google didn’t provide an exact time frame for this feature rollout. If you use Chrome in tablet mode, there is now a new touchscreen interface with larger tabs that are more practical to organize and hide. Google says this was the most popular tab group feature request the team received. Chrome already supports tab groups, but with this release you can now collapse and expand them.
