Intel discusses shift to system-on-a-chip tech

Intel today disclosed technology that it hopes will get more of its silicon inside smartphones and tablets.

At the International Electron Devices Meeting, Intel laid out its next-generation 22-nanometer "SoC" system-on-a-chip technology. An SoC puts most of a device's core functions onto one piece of silicon and is typically used in mobile devices where space and power efficiency are paramount.

"In the past...we were focused primarily on developing transistors with ever higher performance," Mark Bohr, an Intel senior fellow, said to journalists in a teleconference. "Now we're developing technologies with a much … Read more

Apple has big lead over Intel in mobile chips, analyst says

A chip analyst has written a sobering assessment of Intel's chip prowess vis-a-vis Apple in the mobile device race, an odd underdog position for the largest chipmaker.

In the brave new world of tablets and smartphones, chip competition isn't so much about Moore's Law but rather how the "blocks" of circuits are put together and the nexus with the software that runs on those circuits, Gus Richard, a senior research analyst at securities firm Piper Jaffray, wrote in a research note this week.

More specifically, tablets and smartphones use silicon called system-on-a-chip, or SoC, that … Read more

A peek at Intel chip headed to Ultrabooks

More details have emerged on Intel's first system-on-a-chip for mainstream PCs.

That chip, codenamed Haswell, is due by 2013 and will be the first high-performance Intel processor to approach the same level of integration used in smartphones and tablets. Today, Texas Instruments, Qualcomm, and Nvidia are the major suppliers of smartphone and tablet SoCs (system-on-a-chip) derived from the ARM design.

What does Haswell mean for future Macs and PCs? Even more powerful ultraslim MacBooks and laptop PCs will emerge--as well as hybrid laptop-tablet designs.

Imagine, for example, a future 15-inch MacBook Pro as skinny as a MacBook Air but … Read more

IBM pushes toward 22-nanometer chips

IBM is tapping into its computing know-how to get to the next-generation 22-nanometer chip technology.

Generally, the smaller the geometries, the faster and more power efficient the chip becomes. Both Intel and Advanced Micro Devices are moving their processor lines from 65-nanometer to 45-nanometer technology. (AMD, which does joint chip R&D with IBM, is slated to begin doing this in the fourth quarter.)

After 45nm, comes 32nm, which doesn't present any great manufacturing process hurdles. But 22nm is a different story. And IBM is trying to lead the way--ahead of Intel.

At its most basic, photolithography--the conventional … Read more
