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.

Quad core CPU doesn't mean fast cpu either.


Well, it sort of does in practice.

Slow quad core cpu doesn't make sense, since 4 cores is the "high end". It's cheaper to make a dual core cpu that runs at a faster rate than quad core cpu, so if you have a slow quad core cpu, nobody's going to use it.


Apple markets the quad core gpu as means to drive the massive pixels in the new high res display.


Yes, again, fast GPU is important.

Quick, can you name a devite with single core gpu? Or dual core GPU? How many GPU cores does a random ATI radeon have? Or Galaxy S 2?.

It's just marketing. And apparently it's fooling people even here ;-).

No but some people are taking it way out of context just for he sake of arguing and being anti-apple.

Apple just says "Hey we put this really high-res display on this device, if we didn't bump up the processing power you would get laggy performance, which would be so unlike the iPad experience. So we increased graphics performance by adding more GPU performance to our already fast chip"

From the Apple site :"
The A5X chip with quad-core graphics drives four times the pixels of iPad 2 yet it delivers the same smoothness and fluidity iPad is known for. "

Every single mention of the A5x is coupled with the Retina Display feature.

It appears you have utterly misunderstood basic english or are just trying to argue for the sake of arguing or both.

Quick, can you name a devite with single core gpu?


Every single ARM-based cell phone, except those using an MP2/MP4 variant of a PowerVR GPU. The Qualcomm Adreno series are single-core. The TI OMAP CPUs use single-core GPUs. The current-gen ARM-Mali GPUs are single-core (there are multi-core variants of the T-series of Mali GPUs coming down the pipe).

You need to stop thinking in terms of the PC architecture. Everything is different when it comes to ARM.

A GPU "core" is literally an entire GPU. Thus, an SoC with a "multi-core" GPU physically has multiple complete GPUs inside.

Or dual core GPU?


The Apple iPhone 4S and the Apple iPad2 (both using the A5 SoC) have dual-core GPUs, the PowerVR SGX543MP2 (the MP2 part means it has 2 complete copies of the SGX543 GPU onboard).

How many GPU cores does a random ATI radeon have?


Most only have 1. There are a couple of super high-end cards that have 2 complete GPUs on the PCB, configured with CrossFire internally to act as a single GPU. "Stream processors", "shaders", etc are not "cores". There's only 1 GPU core in a standard Radeon GPU. Same with nVidia GPUs.

Or Galaxy S 2?


1 GPU, thus only 1 GPU core.
