Using both cores? - HTC Rezound

In my system monitor app it shows two cores but the second one is greyed out and says its 100% idle the whole time. Does the os not use both cores? Or is the app possibly wrong?

It means it's not being used. The second core is used as more of an 'overflow' core.

Oh OK.. so do you think dual core isn't really necessary? Do any apps benefit from it yet?

They will when ICS comes
It uses both cores natively, unlike GB

Well that sounds nice... This bad boy would probably fly then!

Dual core isn't "necessary" but yeah you will see pretty nice gains when both cores are used on the OS level. Also when more appps/programs are coded for multithreading we will enjoy the extra core. I mean alot of windows 7 phones are still single core and there's like no lag that I've heard about, same applies for iOS. Yes I know each OS has it perks and cons, but with this level of hardware on Android devices we shouldn't have any transitional/UI lag. Hoping that ICS will address this issue finally.

Hmm. I don't think GB is designed truly for dual core, not sure if it fully utilizes the extra core.

that was my understanding. Gingerbread wasn't written to run on two cores, just the one. Hence the reason why until we get ICS, the Nexus will be a "faster" phone as it will actually utilize both cores.

we just need Mango (Windows Mobile 7.5) then we kick it into TURBO speed!... w00t

My understanding of this is that Android at the system level (ie, the underlying linux) is SMP capable and active. Distinct apps will run on each core as the OS sees fit.
What isn't dual core about android is the application layer. A given app cannot multi-thread and use two cores. That comes with Honeycomb +
TL;DR - You get some benefit from Dual Core now - you will get more later.
