Apple A4 iPad Chipset = ARM Multicore Cortex A9 + Mali 50 GPU

According to Bright Side of the News, it turns out that newly spun Apple A4 system-on-a-chip that debuted alongside the iPad does indeed pack more punch than the Sammy in the iPhone 3GS:

A4 is a System-on-a-Chip, or SOC, that integrates the main processor [ARM Cortex-A9 MPCore i.e. Multi-Processing Core, identical to ones used in nVidia Tegra and Qualcomm Snapdragon] with graphics silicon [ARM Mali 50-Series GPU], and other functions like the memory controller on one piece of silicon - not unlike what Intel is trying to achieve with its future "Moorestown" Atom processor that debuted inside LG's Smartphone

Cortex A9 indeed? But no PowerVR SGX like the iPhone. Engadget says this is also similar to the Tegra2 platform. So, it's more of an Apple assemblage of ARM components rather than anything PA Semi unique, but is it a first step towards more customized silicon? Either way, we'd still love to see this baby powering the 4th gen iPhone and iPod touch.

Still no word on RAM though...

They bought PA-Semi to acquire the skill set to do this kind of packaging. Apple has not had that stuff in house for many years now, and the quickest way to get it back was buy it. It might not be a PA-Semi designed from the ground up processor, but they haven't done much of that at this level anyway.
So yeah, it has Pa-Semi fingerprints all over it.

Nice findings here guys, we've covered the future of the Apple CPU over on our blog http://actionjaxon666.wordpress.com check it out!

it uses the nah similar to the Tehran 2... but is NOT bear as powerful as the tegra2. Tegra2 has 8 actually processing cures. The Nah has 1 multiprocessing core. Similar to hyperthreading. Fix your headline. It leads one tl believe its multicore when it is not.

Will says:

MALI? Unlikely. Apple bought stocks in Imagination for a reason, they wanted to integrate PowerVR into their own designs.

After that butchered post you got no call to suggest TiPb fix anything.

A developer friend shared with me that he suspects that it is the older brother Mali 200 or 400 rather than the rather dumber Mali 50 series. The 200 adds programmable vertex and fragment shaders.

It's funny how many engineers respond to this post good job fellas, sarcasm!!!

It's funny how many douchebags responded to this post good job Danny, sarcasm!!!

yobad says:

After watching the iPad video and reading about Mali, i think if the iPad does use a Mali GPU its the 200 or 400 like zeagus said in his post. If apple can get the battery life right and use the a4 along with an HD screen in the iPhone G4, i would gladly give up my jailbreak to have something that responds that fast. 512 mb of ram wouldn't hurt either ;)

Change your language, it leads one to believe it's English when it is not.

Doh!, Wrong its the PowerVR SGX
"Using OpenGL ES on iPad is identical to using OpenGL ES on other iPhone OS devices. An iPad is a PowerVR SGX device and supports the same basic capabilities as other SGX devices. However, because the processor, memory architecture, and screen dimensions are different for iPad, you should always test your code on an iPad device before shipping to ensure performance meets your requirements."
