On the contrary, Mac users will notice a bit more of a difference, with fixes addressing plugin stability and crashing while dragging tabs, a slightly improved cookies manager, and minor tweaks to Chrome’s task manager.
On the performance ( the thing that matters most) Chrome 5 speeds-up Javascript execution by upto 22% as per the Sun Spider Benchmark done on Windows 7:
This Makes Chrome 5 dev “World’s Fastest Browser”.

Apart from performance on Windows, there are two key updates. First, Chrome will now use your default downloads folder (i.e. Username\Downloads on Vista and Windows 7)
Now user has more control over the content Chrome displays and executes. User settings for cookies, pop-ups, plugins, scripts, and images are being moved to their own panel. In addition, user can choose to hide Extension buttons from the bar.
You can download the dev channel build .
