Intel has brazenly announced that dual-core support from the Android operating system is so bad that having a second core is a detriment. Last year some Android smartphones did ship with dual-core processors before the operating system actually supported dual-cores. Dual-core support came with Android 2.3.4 in April of 2011.

Intel is now claiming that it has tested Android with dual-core processors using Android 4.0 ICS and determined that having dual-cores is of little benefit most of the time. Intel also claims that its testing showed the dual cores could be detrimental to performance. The conclusion according to Intel’s Mike Bell is that the Android thread scheduler isn’t ready for multi-core processors.

Yep that was an interesting read, but i guess it should be solved when jellybean comes. I am really looking forward to what intel brings in terms of dual core cpus for phones. They already have pretty good performance in a single core.

JellyBean is basically an update to ICS, no major changes except for it being a more optimized ICS just like how Froyo is to Eclair. Hopefully the scheduling of threads as mentioned by Intel will be finally addressed in this version. That could also mean that even the "dated" hardware on Xperia S would run Jellybean better than it did with ICS. Intel used their wits in this regard, Nokia on the other hand simply used that as an excuse for using ancient HW running in their smartphones.

Funny thing is that 5 years ago Nokia used to have superior hardware and SE is constantly bashed for having crap hardware on their UIQ3 smartphones and even featurephones. The hand of fate moved and now none of the new Nokia flagships could even outclass an Xperia U in everything except Camera. also funny is that Symbian used to be the best OS and is constantly praised by Eldar, but now Nokia couldn't even proudly tell everyone about the OS used on 808 Pureview when they showcased it on MWC.

I too have questioned the need for multiple cores on Android versus the argument of optimizing the software. One simply has to look at what the Windows Phones achieve on single cores clocked and 1.4GHz, or even the first gen Windows Phones running Mango 7.5? They are up there with the best of Android running quad cores!

A quad-core phone... it actually does sound a bit ridiculous.

Samsung have done a great job with optimizing their TW UI with their Exynos dual and quad core chipsets. They are the only Androids that seem to keep a consistantly great UI speed comparable to iPhone and WP despite having a lot more tasks to handle, over the long term. 7months down the line and my GS2 still runs beautifuly despite all the crap i have in it, so i dont see the dual-core as a let down.

A great benefit with these dual-core Androids though is the sheer amount of power in their graphics and video processors, most if not all are capable handling Full HD1080P media, handling flash heavy web sites with no problem and creating 1080p media, if WP's could do that on their dated HW then i id be impressed.

It's because powerful GPUs comes integrated within dual/quad core SoCs. It's impossible to find an ARM based Single Core chip that can do 1080p. Medfield's basis: the Intel Atom could barely run 720p video even though it's got higher MIPS than the yesteryear's Snapdragon 8255.

Multicore SoC's of the future should be able to handle 4K video resolutions, or it'll be pointless for anything other than Gaming, but I haven't seen an Android game that can bring out he full potential of an S4 or Tegra 3 processor.
