Hi, I can't check for another 10 hours, but they changed so many things about AM in 10.9 that I wouldn't be surprised.
Can you get any Processes or combo of them to use more than 100% CPU?

Hi if it's any consolation, my 2011 i7 iMac only shows one CPU in the AM dock icon, but if I choose Window > CPU Usage the popup window shows activity of all the cores separately. I think what you're seeing in the dock is the activity of all the cores combined. I don't know why some people are seeing separate cores though.

I see the two seperate cores in the Dock on my 2009 Mini

I never looked at this before but my 2012 Mini I7 with ML only shows one. How do you make it show 4?

Just found this article. If you have a Hyper threading system you only get one graph (bar) to show:

I haven't got any performance issue yet, fortunately. But I haven't tried serious benchmarking.

My other macbook air (Core i7) shows 4 cores fine as well. Could it be that they use different types of Core i7? I highly doubt it.

I think you had it. Mine does the same, except that my macbook air (late 2012) Core i7 still shows 4 cores in Dock.
But anyways, this at least proves that it's just a UI change.
My take is that the designers had a meeting: Let's dumb it down to just one simple gauge instead of 4 with lots of ups and downs that may intimidate grannies or distract students from homework ..... somewhat in line with their flat-UI. "We are dealing with mature users. No more eye candies."

With previous OS versions the maximum number of cores the Dock icon could show was four. If you have an i7 chip this means you can reach this limit with two physical cores as each physical core can do hyper-threading giving the impression of twice as many cores. Therefore if you have four i7 (physical) cores this would translate to 8 (virtual) cores and be too many to show.
The i5 does not do hyper-threading.
The Mac mini can either have a dual core i5 = 2 threads, or a quad core i7 = 8 threads.
The MacBook Air can either have a dual core i5 = 2 threads, or a dual core i7 = 4 threads.
Therefore the Mac mini quad core i7 will only show as a single 'processor' in the dock but the MacBook Air i7 will show as 4 'cores'.

BDAqua's reply is a good one but I still ran into trouble. I found that you cannot have "Show CPU History" in the Dock Icon. If you disable it, then you can see the core activity.
Go to Activity Manager > View > Dock Icon. Select anything except "Show CPU History"
Then go to Activity manager > Window > CPU Usage.
