We knew that Intel’s Meteor Lake would start an necessary new period with a design that stacks a couple of “chiplets” like pancakes right into a single next-generation PC processor. However now we all know one thing else: A type of chiplets will home an excellent low-power CPU that may hold a laptop computer ticking with out as a lot of successful on its battery.
Intel plans to reveal the brand new design element at its Innovation convention Tuesday. There, Chief Govt Pat Gelsinger is predicted to supply a standing report on his multiyear effort to reclaim Intel’s misplaced processor design and manufacturing management. Meteor Lake, set to reach in laptops later this 12 months, is a centerpiece of 1 section of that effort.
Apple’s M sequence of processors, powering MacBook laptops with lengthy battery life and no noisy cooling followers, have demonstrated the benefits of processor effectivity. Meteor Lake will battle again in two necessary methods, and if Intel delivers as promised, that ought to imply higher laptops for thousands and thousands of us who use Home windows laptops.

First is an replace to the primary mind inside Meteor Lake’s design, a chiplet referred to as the “compute tile” that features a assortment of CPU (central processing unit) cores. As with Intel’s present Alder Lake processors, formally referred to as Thirteenth-generation Core, the processor will embody each large high-performance CPU cores for essentially the most demanding duties and smaller effectivity cores for lower-priority work and higher battery life. Meteor Lake’s CPU cores have up to date designs which are extra environment friendly and which are constructed utilizing the brand new Intel 4 manufacturing course of that is also extra environment friendly, Intel stated.
However tucked into one other tile, the system-on-a-chip (SOC) chiplet, there are much more environment friendly CPU cores on a “low energy island.” The processor shuffles software program duties among the many efficiency and effectivity cores many instances every second to get the very best outcomes, and unused cores will be idled to save lots of battery energy.
“For greatest effectivity, you will see workloads bounced across the cores so much,” stated Tim Wilson, the engineering group vp who led the SOC design. “For lots of people, battery life right now is as necessary as efficiency of their PC. Meteor Lake will shine on each.”
The chip additionally will deliver new talents to speed up graphics on its graphics processing unit and synthetic intelligence duties on its neural processing unit. Each of these are key dimensions of efficiency in trendy machines, significantly higher-end computer systems used for duties like gaming or video and photograph enhancing.
PCs aren’t highly effective sufficient to run the highest-end giant language fashions like ChatGPT, however AI expertise is used for duties like choosing photograph topics in Adobe Lightroom and eradicating backgrounds and audio noise in Microsoft Groups videoconferences.
TSMC, Intel’s competitor and accomplice
Intel is below fierce aggressive strain. Throughout its years of stalled manufacturing progress, Taiwan Semiconductor Manufacturing Co. (TSMC) and Samsung leapfrogged Intel’s as soon as formidable expertise lead.
So did rivals that make chips. AMD made incursions into Intel’s market share, significantly within the server market the place information facilities are full of hundreds of high-end processors. Nvidia tapped into explosive demand for AI processors. And Apple dumped Intel processors, shifting as an alternative to its personal M-series processors and providing compelling efficiency and decrease energy consumption. TSMC builds the processors for all three of these main Intel rivals.

However curiously, TSMC is not simply an Intel competitor. It is also a accomplice. It is manufacturing a lot of the chiplets inside Meteor Lake.
TSMC is constructing Meteor Lake’s SOC tile — the chiplet that homes the low energy island, AI accelerator, video decoder video and Wi-Fi system — on its N6 manufacturing course of. That is additionally used for the I/O tile, which handles input-output chores like Thunderbolt and USB connections.
TSMC’s extra superior N5 course of is used to construct Meteor Lake’s Arc GPU system. It is going to supply twice the efficiency and twice the efficiency per watt because the Thirteenth-gen Alder Lake processors, Intel stated.
Below Gelsinger, Intel is engaged on reworking its personal chipmaking enterprise by turning into a “foundry” like TSMC and Samsung that builds chips for different prospects. It is attracted a couple of purchasers, however the enterprise is not anticipated to select up in earnest till the Intel 18A manufacturing course of arrives, scheduled for 2024.
Chiplets ahoy
Meteor Lake’s “disaggregated” design, enabled by an Intel chiplet-stacking expertise referred to as Foveros, is an indication of issues to come back for the processor trade.
AMD is stacking quick reminiscence caches into its high-end PC processors, and Apple’s M2 Extremely consists of two M2 Max chips linked with a high-speed communication bridge. However Intel is extra aggressive with its chiplet technique, partially due to its have to attempt to catch as much as rivals, Artistic Methods analyst Ben Bajarin stated.
An actual-world instance of Intel’s packaging expertise is Intel’s Sapphire Rapids, a big Xeon processor for information facilities. Intel combines 4 CPU tiles, every additionally referred to as a die or chiplet, into one bigger processor. Intel’s EMIB (embedded multidie interconnect bridge), a skinny sliver of silicon beneath the sides the place the tiles abut, provide information hyperlinks throughout the processor so it behaves like one bigger unit.
With the Sapphire Rapids Xeon chip for information facilities Intel started promoting earlier this 12 months, then with Meteor Lake later this 12 months, a lot of the firm’s two principal product traces will include processors product of a number of interlinked chiplets.
Packaging completely different chiplets will increase manufacturing value and time, nevertheless it additionally gives quite a lot of benefits. Completely different manufacturing processes can be utilized for various chiplets to optimize attributes like value, energy consumption and efficiency. And smaller chips are much less vulnerable to manufacturing defects.
And Intel’s glass substrate expertise, additionally detailed on the Innovation convention, paves the best way for much more superior chiplet approaches. That tumbler — a basis for the bundle that homes a processor — gives higher pace, energy and dimension benefits over right now’s expertise.
Meteor Lake does not use glass substrates, which are not anticipated to reach till later this decade, nevertheless it does illustrate Intel’s packaging talent. For instance, to counteract the warping which means processors are barely flexed like a potato chip, Intel makes use of variably sized solder balls to compensate and guarantee good electrical contacts.
Intel can also use as much as 4 forms of solder balls in its course of, for instance judiciously using extra advanced copper core balls for energy connections. The corporate confirmed off this “multiball” expertise in a tour of its superior packaging analysis labs in Chandler, Arizona.
“As we glance out into the subsequent 5 to 10 years,” stated Tom Rucker, the vp in control of Intel’s meeting integration work, “that packaging goes to turn out to be extra necessary.”
