Apple to move chipset production from Samsung to TSMC with Apple A6 SoC in 2012?

Given the increasing legal contention between Apple and Samsung, perhaps it should come as no surprise that Apple is considering moving production of their next generation Apple A6 system-on-a-chip (SoC) to from the Korean conglomerate to Taiwan's TSMC.

iPad A4 Chipset Uses PowerVR SGX Graphics Core

The iPhone 3.2 SDK for iPad has officially outs the PowerVR SGX as the graphics core inside Apple's A4 chipset:

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.

iPad A4 Chipset Cost Apple $1 Billion?

We typically don't run those stories about iPhone or iPad component costs anymore because they're just silly -- a couple of hundred dollars in metal parts per unit never takes into account R&D and marketing costs, and things like paying $1 billion for the new Apple A4 chipset in the iPad. Or so hints the New York Times:

Imagination at CES: POWERVR SGX545 Graphics Core... Could it be the 4th Gen iPhone GPU?

Imagination, which counts Apple as one of its owners, has provided the GPU (graphics processing unit) for every iPhone to date, including the current iPhone 3GS PowerVR SGX, so it's not unreasonable to assume the latest, greatest PowerVR SGX545 introduced at CES will be in the 4th generation iPhone, likely to be announced in June/July:

SGX545 will also deliver OpenGL ES 2.x and OpenGL 3.2 to deliver class leading 3D graphics performance, and will also support OpenCL 1.0 full profile capability which will enable mobile and embedded applications to take maximum advantage of the capabilities offered by these GPU APIs for both 3D graphics and general purpose applications.

Potential iPhone Gen 4 ARM Cortex A9 Multicore Processor Demo

ARM is showing off their new Cortex A9 multi-core mobile processor, which will scale over 2Ghz at less than 0.25W of power per proc -- and since Apple is rumored to be a massive ARM licensee and Apple staff were hinting that developers should prepare themselves for multi-core, rumors once again resurface that this smoking hot chip might become part of the 4th generation iPhone and iPod touch. (As part of PA Semi system-on-a-chip, 'natch).

The current iPhone 3GS and iPod touch G3, as well as a bunch of competing smartphones (and superphones, don't get us started!) use the ARM Cortex A8. MacRumors is guessing it might just make its way into the iTablet/iSlate as well.

CES is ramping up folks, and remember TiPb will be there, so we'll bring you back anything more we can find out.

iPhone 3GS Doesn't Support HSUPA for High Speed 3G Upload

Macworld is reporting that while the iPhone 3GS chipset does indeed support the new (for North America!) HSPDA download speed of 7.2 Mbps, Apple didn't see fit to equip it with the matching HSUPA upload speed of 1.4/1.9 Mbps. Indeed, they claim the iPhone 3GS will top out its uploads (sending videos to YouTube, emailing photos, etc.) at a comparatively anemic 384 Kbps.
