Intel believes its process technology could eventually give it the lead in low power processing.
LONDON – Though ARM may currently have an advantage in low power processing, Intel believes it could eventually take the lead if it maintains its current pace of advancement in process technology.
Speaking to the firm’s executive vice president and head of architecture David (Dadi) Perlmutter recently, EE Times learned that Intel is pushing ahead with its sub 20-nm and 14-nm plans, while the ARM ecosystem struggles to find a business model beyond 22 nm.

Intel is biding its time. The semi giant appears quite prepared to wait a couple of generations until sub 20-nm nodes are breached before bringing the battle of low power processing to ARM and its mobile partners.
Indeed, Intel claims to have line of sight all the way to a 7-nm process, with all the firm’s CPUs becoming SoCs as of next year. Haswell will be Intel’s 22-nm SoC for tablets and Ultrabooks, while Merrifield will be the company’s SoC for tablets and smartphones.
After that, 14 nm is expected to be Intel's killer node with the most dramatic power improvements and integrated baseband--although the firm has yet to officially announce it.
Meanwhile, the ARM ecosystem has a rather more challenging road ahead of it, with low cost continuing to present a challenge for foundry supply, yield and materials science. ARM is seeing Moore's Law slowing down due to a lack of foundry spending and a deficit in R&D capabilities.
Even at the 28-nm, the ARM ecosystem is feeling the squeeze. Until very recently only one foundry (TSMC) could yield 28-nm chips, with Globalfoundries just starting to produce 28-nm in volume, and the entire industry is under-supplied.
With Intel pushing ahead to introduce FinFETs at the 22-nm and hoping to use EUV lithography at 14 nm and below, ARM faces an even bigger crisis of competition.
Meanwhile, Intel’s design teams work hand in hand with the the company's fabs, in one unified effort. “We always work very closely with the fab,” said Perlmutter. “Each time we put a new big challenge in front of the giant team,” he said, adding that every time the focus centered on new and different aspects of the technology.
“If you develop technology, every day you bounce into a problem which may seem to be a showstopper,” he explained, discussing the various challenges the teams had overcome hitting the targets for Haswell’s design.
“What looked to be hugely complicated 10 years ago looks like a piece of cake now. We have to overcome new things every time around, so we have an 'aha' moment every day, every minute in every single Intel product,” he said.
Analysts say that Intel now has about a 2 year lead in process technology. This is a huge advantage. And as the lithography & equipment complexity & cost goes up with each new generation it's more difficult to keep up and even afford to build new fabs. Intels new 14nm fabs are about $7B each and the list of those who can afford it has gotten much smaller. Today, only Intel, Samsung & TSMC can afford them. This is one reason why Intel is getting into the foundry business too.
I'm not sure where you're looking but costs of Atom chips to Intel are 10x cheaper than their PC chips because they're so much smaller. 22nm chips are cheaper than 32nm and 14nm are cheaper than 22nm versions. Of course, the performances go up and the power down each new generation too. 14nm will be a killer chip for Intel that ARM won't be able to match
Human civilization continues to advance due to the species' unique ability to build on knowledge. Today's engineers are smarter (read Scientific American Sept 2012, p44). Dadi Perlmutter is as brillian an engineer and manager as you will ever meet, which explains his current responsibilities. Dadi "gets it" and has for more than 15 years. He also gets people, has the humilty and wisdom to attract and utilize the best among us.

One hope ARM has is that IBM's design for yield tools and SEM/TEM capabilities are helping GF get their Malta fab up and running faster. And ARM-GF have new long term partnership lately. IBM may have learned to be more agile and sneaky that in distant past when they let intel empower the cloning of their PC's by using the easy-to-rev-eng BIOS ROM chip. But its all about execution, so we will see over next 3 years. Maybe Warren Buffet realized this was a game he did not understand? Risk is very high next 3 years.
Before, when buying a PC, the CPU (Intel or AMD or whatever) was the key thing. Now, when buying a tablet or smartphone, most will not care if it's an ARM or Atom processor inside. They would only care about the final product design by Apple, Samsung, or whomever.
