At its silicon core, the fourth-generation iPad is hardly an incremental upgrade, according to chip analysts.

The new iPad's A6X chip packs a brand-new graphics engine that boasts a serious step up in horsepower from the third-generation iPad's A5X.

"Nothing's incremental about this. The A6X is one massive processing machine," Jim Morrison, a product manager at Chipworks, which does reverse engineering and patent-infringement analysis of semiconductors and electronic systems, told CNET.

Chipworks posted an analysis of the A6X's circuit layout today.

The new iPad isn't waltzing into a competitive vacuum. That wow-worthy display notwithstanding, Apple still has to go head-to-head on performance.

Chip-review site Anandtech confirmed with Apple that sitting right next to the A5X's quad-core GPU (graphics processing unit) is a dual-core CPU (central processing unit).

Apple had nothing to say about the CPU (which typically garners the most attention) when it announced the new iPad, because the CPU really hasn't changed from the iPad 2.

The upshot is that Apple is pitting the A5X's quad-core GPU against a quad-core Nvidia CPU.

So, how does it … Read more

Apple has just elevated the graphics chip to superstar status. Why focus on the graphics?

Apple announced today at the iPad event in San Francisco that the new iPad has a quad-core graphics processing unit (GPU). (So much for the central processing unit, or CPU, which typically garners all of the attention.)

So far, chip review site Anandtech offers the best educated guess about the graphics engine. Anandtech cites graphics chip technology from Imagination (PowerVR SGX543MP4) and CPU tech from ARM (Cortex A9).

"Our guess? Dual-core Cortex A9 [CPU] plus a PowerVR SGX543MP4 [GPU], an upgrade over the 543MP2 … Read more

LAS VEGAS--Texas Instruments is offering one of the most revealing demos of Windows 8 on ARM yet at CES.

That's not saying a lot, though, as demos of Microsoft's next operating system on ARM processors have been extremely restrictive, if nonexistent to date in public (Nvidia's untouchable, relatively static CES demo is behind closed glass). But TI pushed the boundaries a bit in a demo for CNET at CES.

The demo tapped TI's freshly minted OMAP4470 ARM processor, according to Bill Crean, an OMAP product marketing manager.

Needless to say, I was not permitted to take … Read more

LAS VEGAS--Texas Instruments is showing its latest and greatest ARM processor inside a Windows 8 tablet at CES this week.

TI's OMAP4470, the latest version of its dual-core chip now inside Android tablets, will be shown running on a pre-release version of a Windows 8 tablet, the chipmaker said today.

"The OMAP4470 processor's...powerful multitasking capabilities prove the ideal match for Windows 8 key features including a fast & fluid touch-first user interface," TI said in a statement.

TI ARM chips are being used today in high-profile Android tablets such Motorola's XyBoard and Toshiba's ultra-skinny Excite X10. The 4470 is a performance upgrade of the 4460.

"The company calls it the OMAP 4470, but it is more than just a faster speed grade of the OMAP 4460; the new design includes significant graphics and memory improvements as well," mobile chip analyst Linley Gwennap wrote in a blog last year. … Read more

Despite a globe-spanning, bruising legal battle with Samsung, Apple has little choice but to keep getting key parts for its iPhone from the electronics maker, according to sources and a news report.

Those key parts include the iPhone 5's expected main processor, the A5, as well as system memory and flash memory--components that together make up the electronic core.

Sources who track the chip industry say that Apple must stick with Samsung for the time being. Some rumors had claimed that Apple would switch to Taiwan Semiconductor Manufacturing Company (TSMC) for a so-called "shrink" (smaller version) of the A5 for the iPhone 5.

That's simply not doable, sources tell CNET. TSMC has not perfected the advanced manufacturing processes needed to make an A5 for the iPhone and, maybe more importantly, it's prohibitively difficult to jump to a different manufacturer for the same chip design. … Read more

Wondering what makes that iPad 2 you just got tick and how much faster it is than the original iPad? Anandtech, iFixit, iosnoops, and UBM TechInsights have provided some answers.

Processor performance: Let's address this first--for obvious reasons. Apple has already been very public about the dual-core 1GHz A5 processor--a step up from the single-core chip in the original iPad--and the chip's "up to 9X faster" graphics" (Apple's ad copy).

And the verdict from an independent review? "CPU [Central Processing Unit] performance...we found to be a healthy 50 percent faster than the … Read more

Apple has taken a small stake in a British chip designer, revealing how the company plans to power the graphics in future iPhones and iPod Touches.

Imagination announced Thursday that Apple has acquired a 3.6 percent stake in the company, which will only cost Apple 3.2 million pounds, or about $5 million. Imagination designs chip cores for a variety of applications, but its most prominent designs are its PowerVR cores for graphics in mobile phones.

That is believed to be the source of Apple's interest in the company, according to AppleInsider, which has tracked Apple's interest … Read more
