Apple And it was that time of the year again - Apple held one of its product announcements. This one focussed on the iPad mostly, and while some will call it a disappointment merely because virtually everything had already been leaked, I'm still in awe over the fact the newly announced iPad has a 2048x1536 display. My mind is blown.

People that know about this PowerVR convention are not the ones being targeted by the Apple marketing speak in the launch comms. Apple is using it to steer the eye away from the fact that they only have a dual core CPU.


What's wrong with "only having a dual-core CPU"? It's not like there's a heavy demand/need for multi-tasking on a tablet. Especially considering the lack of "true" multi-tasking in iOS. The biggest "need" in a tablet with this high of a resolution is graphics hardware. And that's what the A5X comes with: the ability to pump pixels faster than just about any other ARM GPU out there right now (things will change with the Adreno 300-series and the ARM Mali-T-series).

Anandtech has some blog posts about demonstrations by ... someone (TI?) with 4 videos playing at once, and not being able to stress the quad-core CPU inside.

Fast, power-efficient dual-core CPU with uber-fast GPU with all kinds of hardware decode capabilities is where it's at for tablets (and, most likely, cell phones).

Will be interesting to see how ARM's big.LITTLE architecture plays out near the end of this year/beginning of next year. High-frequency, dual-core Cortex-A15 matched with low-frequency Cortex-A7 (with some kind of next-gen GPU) should pretty much be nirvana for any mobile task. ;)
