Intel is rethinking the way it releases — and types — its semiconductor improvements, CEO Pat Gelsinger introduced at present on the firm’s Intel Accelerated webcast. The announcement consists of the broad strokes of the subsequent half-decade of Intel’s processor roadmap, new chip and packaging applied sciences, and a promise of an “annual cadence of innovation,” with the final word objective of seeing Intel retake its management within the processor area by 2025.

Future Intel merchandise (beginning as early as its upcoming 12th Gen Alder Lake chips later this yr) will not use the nanometer-based node nomenclature that each it and the remainder of the chipmaking trade has used for years. As a substitute, Intel is debuting a brand new naming scheme that it says will present “a extra correct view of course of nodes throughout the trade” and the way Intel’s merchandise match into that panorama.

How that works in apply is that these new third-generation 10nm chips shall be known as “Intel 7,” as an alternative of getting some 10nm-based identify (like final yr’s 10nm SuperFin chips).

At first look, it sounds lots like an affordable advertising and marketing tactic designed to make Intel’s upcoming 10nm chips look extra aggressive subsequent to merchandise from AMD, that are already on TSMC’s 7nm node, or Apple’s 5nm M1 chips. And whereas that’s technically true, it’s not as unfair of a comparability because it essentially appears to be like. In trendy semiconductors, node names don’t really confer with the dimensions of a transistor on a chip: due to advances like 3D packaging applied sciences and the bodily realities of semiconductor design, that hasn’t been the case since 1997 (as noted by ExtremeTech).

And from a technical perspective, Intel’s 10nm chips are broadly on par with “7nm” branded {hardware} from rivals like TSMC or Samsung, utilizing related manufacturing applied sciences and providing comparable transistor density. That’s one thing that interprets to business {hardware}, too: we’ve already seen that Intel’s current 10nm chips are nonetheless aggressive with AMD’s cutting-edge 7nm Ryzen chips, for instance.

All that’s to say that Intel’s rebranding right here isn’t fully unfair to see, even when it does make it tougher to parse when these greater “node” change advances are occurring with the brand new nomenclature.

Intel’s up to date roadmap and node naming

Right here’s a have a look at Intel’s new roadmap and what all of it really means.

• Intel 7 is the new identify for what would have been Intel’s third-generation 10nm know-how and the successor to Intel’s 10nm SuperFin (aka Intel’s second-generation 10nm chips, discovered most notably in its eleventh Gen Tiger Lake chips). Intel says that the brand new Intel 7 {hardware} will provide roughly 10 % to fifteen % enhancements in performance-per-watt in comparison with the earlier era — or, as is all the time the case, improved energy effectivity and battery life ought to {hardware} producers want to maintain efficiency the identical.

The primary Intel 7-based merchandise will present up as early as this yr, with the already previewed Alder Lake chips coming on the finish of 2021 for client merchandise, and the upcoming Sapphire Rapids chips in 2022 for information facilities.

Intel 4 is the structure formally generally known as Intel’s 7nm course of, which Intel infamously was forced to delay out to 2023 final summer season following manufacturing points. Initially deliberate for 2021, it’s the subsequent main bounce in know-how for Intel, utilizing EUV (excessive ultraviolet) know-how — one thing already utilized by Samsung and TSMC’s 5nm node merchandise, for comparability. It’ll nonetheless use the identical broad FinFET transistor structure that Intel’s been utilizing since 2011. Due to all these enhancements, Intel 4 is anticipated to characteristic a transistor density of about 200-250 million transistors per mm², in comparison with about 171.30 million transistors per mm² on TSMC’s present 5nm node.

Intel says that Intel 4 will provide an roughly 20 % bounce in performance-per-watt whereas slicing down on general space. Manufacturing is ready for the second half of 2022, with the primary Intel 4 merchandise deliberate for 2023 (Meteor Lake for client merchandise, and Granite Rapids for information middle).

Intel 3, set for manufacturing within the second half of 2023, is the brand new identify for what would have been a second-generation 7nm product underneath Intel’s earlier naming scheme. Like Intel 4, it’s nonetheless a FinFET product, though Intel says it’ll provide further optimizations and use of EUV for roughly an 18 % enhance in performance-per-watt in comparison with Intel 4. No launch date or product names for Intel 3 chips have been introduced but, however presumably, they gained’t be out there till 2024.

  • Intel 20A is the identify for the subsequent era of Intel applied sciences that, underneath the {old} scheme, would have been the structure following the previously branded 7nm node. It’s additionally probably the most substantial announcement that Intel made at present, technologically talking, one that can see Intel debut its first new transistor structure since FinFET in 2011, referred to as “RibbonFET.” The brand new structure will mark Intel’s first gate-all-around transistor, a essentially new transistor know-how for the corporate that guarantees higher transistor density and smaller sizes. Moreover, 20A will see the introduction of “PowerVia,” a brand new know-how that permits for wafers to be powered from the again of the chip, as an alternative of requiring energy to be rounded to the entrance.

A more in-depth have a look at the approaching updates for Intel 20A.
Picture: Intel

The “20A” within the title is supposed to evoke the “Ångstrom period” of semiconductor design — an Ångstrom being a unit of measurement smaller than nanometer. (20Å = 2nm, though, like the opposite rebranded Intel names above, Intel 20A doesn’t confer with a particular measurement on the merchandise themselves.)

Intel’s 20A isn’t anticipated to ramp till 2024, and, like Intel 3, it doesn’t have any formally introduced launch date or merchandise but.

  • Intel 18A is the farthest sooner or later piece of Intel’s roadmap and can characteristic the second era of Intel’s RibbotFET know-how for “one other main bounce in transistor efficiency.” Intel says that Intel 18A is in improvement for “early 2025,” and that it expects this era of know-how to re-establish its semiconductor management.

Along with all of its course of roadmap information, Intel additionally introduced two main updates to its Foveros chip-stacking packaging technologies (the second-generation of which is ready to debut in Intel 4’s Meteor Lake in 2023.) Foveros chip stacking combines a number of {hardware} parts right into a single die, like Intel’s Lakefield chips, which pile collectively 5 CPU cores, an built-in GPU, and DRAM right into a compact stack to avoid wasting inside area in comparison with a standard design.

Picture: Intel

Foveros Omni will permit for extra selection in stacked chips by making it simpler to mix-and-match tiles, no matter their particular dimension — for instance, permitting for a base tile that’s smaller than the highest tile in a stack. And Foveros Direct will permit for direct copper-to-copper bonding between parts, decreasing resistance and lowering bump pitches. Each of the brand new Foveros applied sciences are deliberate for manufacturing in 2023.


Intel’s new names could assist the corporate recontextualize its present and future merchandise extra precisely towards its competitors, however the truth stays that Intel is behind. Even accepting that the Intel 7 is on par with 7nm merchandise from different foundries, these foundries are already previous their 7nm chips and on to 5nm {hardware}. Which implies that the businesses that depend on these exterior foundries — like Apple, AMD, Nvidia, Qualcomm, and nearly each different main tech firm — can nonetheless get chips which are extra superior than Intel’s greatest work. Apple’s superlative M1 Macs, for instance, already use 5nm chips from TSMC — and handily outpace Intel’s comparable merchandise. AMD is rumored to be engaged on 5nm Zen 4 processors for as early as 2022, too, which may provide equally regarding competitors for Intel from its already encroaching competitor.

Even with the formidable, annual cadence for its roadmap, Intel is enjoying from behind; it doesn’t count on to totally catch as much as the remainder of the trade till Intel 20A in 2024. And it doesn’t count on to reclaim management within the semiconductor enterprise till 2025 with Intel 18A. And all that assumes that Intel doesn’t hit any extra delays or manufacturing snags like those that held up each its 10nm and 7nm processes (which arguably put the corporate in its present scenario within the first place).

After years of setbacks, although, it’s clear that the revitalized Intel isn’t happening and not using a struggle. However the subsequent few years will see whether or not its efforts are sufficient.
