Google Chrome and many-cored CPUs

[Quartz]

One of Chrome's original USPs was that it separated each tab out into its own process (up to a limit) so that misbehaviour by one would not affect others. Nowadays there are consumer-level CPUs with 12 to 32 cores, so how does Chrome scale? How does Chrome fare on a 2990WX? On a 3900?

Exactly the same as it fares on a single core, dual core, or any other processor - it still creates a new process per tab

Well yes, but does a many-cored CPU improve the usability?
