Was there a change in behavior of Activity Monitor between Leopard and Snow Leopard?

My wife has MacBook Pro (Late 2007, 2.4/2.2GHz) with Intel Core 2 Duo processor running Leopard.

I have MacBook Pro (15-inch, Early 2011) with quad-core Intel Core i7 processor running Snow Leopard.

When we open Activity Monitor and switch to the CPU tab to show CPU usage, my wife sees a separate indicator for each of her cores. I see only one, although CPU usage is reported over 100% at times.

Is there a trick to display an indicator for each of the cores on my laptop?

In Snow Leopard double-left-click on the CPU-usage graph to get seperate graphs for all Cores of your i7.

I can't say I like this change but I guess I have to live with it.

I found the following thread also of relevance:

Personally I think it is quite nice to only have the floating CPU window open and hide the "full" Activity Monitor window.

Especially on a 6-core Mac Pro (12 shown with Hyper Threading).

Well, floating window has been available before as well and it is indeed nice to have if one wants to watch continuously. However, for a quick peek when troubleshooting, having to open the extra window after launching the program is just an extra step and the extra window covers some other stuff. Giveth and taketh.
