Apple’s Partitioning

Staying in Palo Alto this week, I was lured, as one is, to the Apple store.

And came out, unsuspecting and unintentionally, owning an iPad.

 

It seemed sluggish. A browsermark test rated it around 70k. It had iOS 4.3.5 on it.

 

Upgrading to iOS5 took the rating to 100k.

 

Now the iPad 2 is dual core, iOS5 is written for dual core and iOS 4.3.5 is written for single core.

 

So all that figures. But a 30% increase seems an impressive tribute to Apple’s ability to partition tasks over multiple cores.

 

Particularly so, when I haven’t noticed any improvement in performance in my x86 stuff for years however many cores Intel and AMD stick on their chips.

 

Incidentally a browsermark test on an Atom-based netbook produced a rating of 12.5k.

 

Roll on the ARM-based laptop.

    iOS/Safari cannot run the Browsermark benchmark properly … there is a stage where it renders a rotating crystalline tree which is completely skipped using Safari. You cannot compare scores on iOS with those on Android who complete all stages of the benchmark properly.

    Would be interesting to know the performance of ARM based non Apple tablets. (Yes, they exist :-))
