Faster 10th-gen Ice Lake laptop chip gives Intel some of its mojo back
Portable PCs with better performance and battery life will arrive later this year.

After four years,
finally has a new processor design.
And it's something the company doesn't have to be ashamed of. Ice Lake -- officially Intel's 10th-generation Core processor -- clocks in at roughly 18% faster than its predecessor, Intel said. The processor's graphics speed is 50% to 80% faster, and dedicated circuitry will boost AI software and double video-handling speeds.
The new processor also has built-in Thunderbolt support for faster connections to external devices, and a companion chip brings improved Wi-Fi 6 wireless networking. It's also got better gaming performance, with Intel demoing an Ice Lake laptop playing Destiny 2 at its Computex keynote.
The new chip kickstarts Intel's manufacturing process, which stalled with the previous Sky Lake design. The earlier chip was supposed to be on the market for two years, but Intel instead extended its life with modest tweaks while working through its manufacturing problems.
Ice Lake will likely usher in thinner, faster and more capable
. Software should also improve to take advantage of the more powerful brains that can run it. Combined, we might actually have a reason to put our
down and upgrade our PCs.
In a separate plan, called Project Athena, Intel detailed the changes it hopes to bring to PCs. The company aims to enable a PC with processing power, snappy response and long battery life. Today, PC customers often have to choose which of those are a priority and which they'll sacrifice, but Athena is designed to deliver it all.
Finally, Ice Lake's new manufacturing process
Intel executives, describing their product ahead of the
show in Taiwan where Ice Lake's specs were unveiled, were eager to discuss something other than the Sky Lake designs that arrived in 2015. Back then, Intel had a "tick-tock" approach to chip progress. A tick in one year moved to a more advanced manufacturing process, and a tock the next year updated the fundamental chip design, called its microarchitecture.
That system collapsed when Intel couldn't get reliable results from its new manufacturing process with smaller circuitry. It's been harder for the chip industry to keep pace with the steady progress charted by Moore's Law, named for Intel co-founder Gordon Moore, but Intel was stalled on 14nm even as TSMC and
Ice Lake is built with electronics features that measure 10 nanometers -- about five times the width of a DNA strand. That size lets the company cram twice as much circuitry into a given area compared with today's 14nm chips. Intel has been stuck on the 14nm "tock." The company has refined its 14nm process significantly and offered some rare 10nm chips. Still, Ice Lake marks the first serious arrival of 10nm manufacturing. It also introduces a new microarchitecture called Sunny Cove.
"We've overhauled the microarchitecture to get better performance out of the box," said Ronak Singhal, Intel's director of CPU computing architecture. "Your apps will get faster just by moving to the latest hardware."
Smaller circuitry lets Intel put more electronics on the chip, and one of the biggest beneficiaries here will be those who like Intel's all-purpose Thunderbolt connector. Adding all that circuitry means Ice Lake chips are significantly bigger than they could have been, though, which means Intel can't make as many of them from each 300mm silicon wafer it sends through its manufacturing lines.
As circuitry shrinks, though, chipmakers pile more and more duties onto processors that previously relied on separate chips. "In our history, we never went through an integration of this size since we integrated graphics on Sandy Bridge," chips Intel debuted in 2011, said Ophir Edlis, a senior principal engineer.
Intel not out of the woods yet
Ice Lake is a big deal for Intel, but it's not victory.
For one thing, its use of 10nm manufacturing will be limited. Processors for
-- plugged into the wall for power and thus not needing Ice Lake's better efficiency -- will continue to use the Sky Lake design built on the 14nm process. "10nm has ongoing yield issues," Kanter said, meaning that an undesirably high fraction of chips don't meet quality standards.
Another challenge is that smartphone chipmaker Qualcomm is eager to sell its own Arm-family processors to make PCs work more like phones with long battery life and connections to mobile networks.
and others used to living in Intel's world will likely provide the software support that will require.
Finally, there's Apple. It just upgraded its influential MacBooks to ninth-generation Intel Core processors. But moving to Arm processors, as persistent rumors suggest is likely, would be a major blow to Intel. Apple declined to comment on its plans.
With Ice Lake, though, Intel can legitimately say it's again moving forward, improving power and performance.
It expects improvements over Ice Lake's Sunny Cove microarchitecture -- Willow Cove in 2020 and Golden Cove in 2021. Intel's next-generation 7nm manufacturing process is due to go online in 2021, too, shrinking circuitry further. And its Foveros chip-stacking technology could enable more performance and flexibility.
"Things haven't been as exciting in the processor world for many years," said Christopher Voce, a Forrester analyst. With Ice Lake, though, "Everything they've shown is impressive. They turned it up a notch."
