Intel to Outsource Some Key CPU Production for 2023 Chips to TSMC

Intel made several big announcements about its 7nm tech at today's Intel Unleashed: Engineering the Future event and divulged that it expects that the majority of its products in 2023 to still be produced in-house using its own manufacturing technology. But there's a caveat: Intel CEO Pat Gelsinger said the company will also release "leadership CPU products" in 2023 with CPU cores that are fabricated with an unspecified process node from third-party foundry TSMC, and those CPUs will come to both the client and data center markets.

This development comes on the heels of Intel's announcement last year that its 7nm process was delayed, possibly forcing it to do the unthinkable — turn to external foundries to produce its core logic, like CPUs and GPUs, for the first time in the company's history.

The newest announcements mean that, in addition to the 7nm Meteor Lake desktop chips and Granite Rapids data center processors that Intel will produce with its own process technology in 2023, the company will also release other lines of CPUs in 2023 that will use CPU cores with an as-yet-unspecified process node from TSMC. Intel noted that the chips that utilize TSMC's third-party process tech will power Intel's "CPU leadership" products for both the client and data center markets, suggesting a split product stack.

Intel says that the majority of its products in 2023 will come manufactured with its own process technology. Still, it's important to note that Intel hasn't specified that the majority of the newly-released 2023 products will come with its own 7nm process. Naturally, Intel will still have plenty of chip production volume centered on its 14nm and 10nm process tech in that timeframe, and even older nodes that still ship in large volumes.

Intel's distinction that its line of "leadership CPUs" with outsourced cores will come for both the client and data center markets could be telling. TSMC plans to begin high volume manufacturing of its 3nm process in the second half of 2023, meaning that Intel's 7nm could be outmatched by competitors, such as AMD, Apple, and ARM-based designs, with CPU designs etched on a more advanced node than Intel's. Samsung will also have more advanced 3nm technology than Intel in the same time frame. 

TSMC and Samsung's newer process nodes might not be faster than Intel's 7nm; clock rates on newer nodes are expected to remain static or even possibly regress, but CPU architectural modifications can offset those issues. However, the denser processes will absolutely be more power-efficient and cost-effective (even though per-transistor costs are rising with denser nodes), leaving Intel at a disadvantage against competing chip designers that have access to more advanced process technology.

As such, Intel's secondary lineup of leadership CPU products with outsourced cores could be comprised of the highest-end halo products built with the latest process node from TSMC, providing the company with more performance than it can achieve on its own process tech.

As we see with most semiconductor manufacturers, Intel's highest-end parts comprise a smaller percentage of its overall chip production. In fact, the mid-range and lower-end chips often comprise the overwhelming majority of sales, while halo products offer the highest-end performance at a premium and reinforce performance leadership and the brand.

Setting aside its highest-end products for an external process node makes a lot of sense — Intel currently produces more x86 processors than any other company, producing in the neighborhood of one million dies per day. That means that no single outside foundry can satisfy its production requirements. For instance, Intel has more than twice the semiconductor revenue of TSMC. Given that TSMC is already capacity constrained, it obviously wouldn't have enough output to satisfy all of Intel's incredible sales volume.

Intel will also likely leverage its packaging tech to reduce the number of externally-sourced components required to build a full chip. It's feasible that Intel could 'simply' swap out its own 7nm CPU tiles found in its Meteor Lake and Granite Rapids chips in exchange for compute tiles based on TSMC's smaller process node to build more competitive variants. Or we could see entirely different models based on the third-party process tech.

As the highest-end products typically comprise the smallest amount of overall sales, outsourcing portions of its high-end CPUs would allow Intel to satisfy its larger production volume requirements with its own 7nm tech, while remaining competitive with its lower-volume leadership products fabbed on an external process node. 

Intel also isn't divulging whether it will fab the chips with an external process in its factories via a technology licensing agreement or if the chips will be built at TSMC. Outgoing CEO Bob Swan told us that technology licensing was a possibility.

Intel has a long history of producing low-value simple chips at several foundries, like TSMC, Samsung, GlobalFoundries, and UMC. Intel has also traditionally used third-party fabs, currently to the tune of ~20% of its production, for low-margin, non-CPU products, like chipsets and Wi-Fi chips, built on trailing-edge nodes. Intel hasn't shared how much it expects to expand manufacturing with third parties.

    Continuing to report that Intel has “twice” the production of TSMC based on revenue numbers is nothing short of misleading. It’s disingenuous and bad journalism.

    The relevant metric is not revenue but Wafer Starts per Month. At last check, Intel pumps out 1/3 the number of wafers that TSMC does.

    Yes, there isn’t enough fab capacity on earth for Intel to abandon its fabs. It’s a slow-moving industry with huge capital expenditures, advanced favs simply don’t sit idle. At the right price, TSMC could produce Intel’s entire output 3 times over however.

    Intel is no longer the dominant fab. That’s been true for years. Making misleading comparisons that put Intel in the lead won’t stop Intel from going the way of IBM(alive but no longer dominant). How about you write an article on production output so you don’t need to keep referencing your “twice the revenue” article?

    TSMC only has so much space for making wafers and that means if they are now doing Intel's chips you will be getting that many less video cards produced around the world because of it.

    Get ready to run your gaming PC on built in Intel chip video! 720p Ultimate graphics here I come! :p

    So Intel is basically throwing in the towel on 10nm and acknowledging they aren't going to get it right.

    I see a "SmartFoundaries" spin off in the near future.

    well that's because Intel is selling directly selling its products and not comparable to TSMC. consider that TSMC has bought most of the ASML EUV equipment and Intel only bought a few and lost their technical manufacturing for years already.🙄

    For instance, Intel has more than twice the semiconductor revenue of TSMC.

    But that's even more depressing for TSMC, what is going on there?! Is their 7nmp such a small part of their production? How can they be making so little money from so many waffers otherwise? Usually businesses pay top dollar for top product.

    Like I told you before ,that you so Cognitively dissonantly dismissed.
    I was right Eh!

    TSMC is preparing its 5nm process, so part of its usual production line is out of commission while it is in the process of recalibration for the new node.
    Once its 5nm is properly prepared on all new lines, TSMC will be back up to full production and Apple will be its first customer with the new line of Custom Chips.

    Not only will Intel be now changing to 7nm, we can assume that it will go to conventional 2D design meaning now Intel will be 2-5 years behind the competition.

    Intel Fans Love to live in the Good old days. They don't want news like yours.

    How is that changing anything?!
    Why did they have to stop 7nm production to increase 5nm production when they are making 3 times as many waffers as intel?!
    The only explanation would be if almost all their production is on very old nodes and they only have a very small amount of fab space that can do any sort of high tech node forcing them to exchange one for the other.
