It’s not clear if Apple have discontinued Safari, but with it’s high memory usage in this test and terrible load time of the 10 test pages, I’m not sure why anyone would want to use it.Avant’s nice idea of 3 different switchable browser engines in the same browser sounds like a good idea, but needs a lot more work to make it fully optimized and really worth using.Firefox has improved a lot recently in resource usage, but few people run it without plug-ins so the memory usage and load time will likely increase when several are added.The interface is not the best, but compatibility should be good as it uses the Internet Explorer Trident rendering engine. A resource friendly surprise was GreenBrowser as it loaded fast, was low on memory and kept CPU usage to a minimum.Predictably Opera was the fastest to load and stayed low on CPU usage when viewing Flash rich pages, although the problems it still has viewing some webpages properly might put people off.Do note the “Peak CPU usage” is AFTER the pages have fully loaded and not while loading, all browsers hit 100% during that time. Green is obviously the best and pink is the worst for each category.

To summarize the results from all the browser’s RAM and CPU usage, here’s a simple table showing the scores. On testing, the 64-bit version peaked at 71% CPU and used 351MB of memory. CPU Usage: Mostly between 0% and 10%, peaked at 60% during Flash animation.ĭownload Internet Explorer 9 (Vista and 7 only)ĬPU Usage: Mostly between 0% and 10%, peaked at 54% during Flash animation.ĬPU Usage: Mostly between 0% and 10%, peaked at 61% during Flash animation.ĬPU Usage: Mostly between 0% and 7%, peaked at 30% during Flash animation.ĬPU Usage: Mostly between 3% and 10%, peaked at 81% during Flash animation.
