Today Intel’s CEO Pat Gelsinger has outlined two key changes to Intel policy: one derived from Intel’s plans to offer foundry services to external partners, and the other from Intel starting to outsource its core compute product families in order to get the best product at a given time. Not only is Intel set to offer x86 core IP to customers through its new Intel Foundry Services, but also Intel is looking to creating leadership compute products on external nodes. These are complete 180º turns from how Intel has previously operated.

For the last 20-25 years, Intel has been steadfast in keeping the crown jewels of its product design firmly inside its very protective walls. Over the years, Intel’s x86 designs have mostly led the market in leadership performance and power (except for Pentium 4 and Rocket Lake), and limiting use/production for Intel-only use has enabled the company to improve that design with laser focus, manufacturing not-withstanding. Keeping the cores for internal use only means that neither customers nor competitors were able to see the raw design specifications, and for a long time this has enabled Intel to keep key features, such as its branch predictors, away from all but the most prying eyes.

In a twist to the norm, Intel is now set to dissolve those walls keeping its x86 cores it itself.

First up is Intel’s Foundry Services, a second crack at offering external customers the ability to use Intel’s manufacturing facilities. Idle fabs are costly, and so with IFS, Intel wants to enable a revenue stream while at the time meeting global demand for semiconductors, especially as it pertains to local supply chain security and migrating the world’s semiconductor reliance away from Asia more into the USA and EU. IFS will stand as a separate business unit inside Intel.

As part of IFS, Intel will both offer raw manufacturing services, similar to a standard foundry like TSMC and Samsung, as well as its portfolio of IP to customers. This is a Big Deal™.  Intel will enable a fully vertical model with its IP portfolio, allowing customers to choose from x86 cores, graphics, media, display, AI, interconnect, fabric, packaging, and other critical foundational IP from other sources (such as Arm, RISC-V). The exact way in which customers will be able to license the IP will be announced in due course, but if Intel were to follow the Arm model, then Intel customers will get access to Intel’s 86 core designs.

Arm’s model is bidirectional: core IP and architecture IP. The first allows you to build an SoC with defined cores, while the latter allows you to build your own cores with the instruction set (like Apple does with Arm). When applied to Intel, with the core IP, a customer can build designs based on Intel’s x86 cores with their own or external interconnects, or in different configurations to Intel’s standard model that are more optimized for what that particular customer requires. At the minute Intel is set only to offer core IP licenses, not architecture IP licenses.

If we take this idea and extrapolate, we could very well see x86 cores combined with new memory controllers, active interposers with custom interconnects.

Intel has kind of done this before, although it was very much a walled garden. Intel offered foundry services almost 7 years ago, under then CEO Brian Krzanich, that allowed very select customers to build new SoC designs, with Intel's help, and only for very select pre-approved use cases. In that time, Intel's effort for a proper foundry business was, in Gelsinger's own words, 'weak'. The new model is set to be more open, as far as we're led to believe.

The only question becomes to what extent will Intel offer x86 cores. Will it be the latest cores designed internally, or would they be a couple of generations behind? Will those designs be offered on a variety of process nodes, or just on a singular process node? Would a customer be able to get a core IP license and build it at another fab? This is where the second part of the announcement comes in.

As part of today’s announcement, Intel has stated that it will be expanding its use of third-party foundry capacity. Pat Gelsinger highlighted that it would be leveraging its relationships with TSMC, GlobalFoundries, Samsung, and UMC, to enable the best manufacturing facilities for its leading edge product designs, from communications and connectivity to graphics and chiplets. This builds on the announcements made by former CEO Bob Swan last year in light of Intel's own troubles on its 7nm process. Today's announcements reaffirms Swan's messaging, given that at the time the word 'pragmatic' was used, so while this has probably been in the works in a while, it is good to get a clear confirmation. As part of this announcement, to quote:

‘Gelsinger said he expects Intel’s engagement with third-party foundries to grow and to include manufacturing for a range of modular tiles on advanced process technologies, including products at the core of Intel’s computing offerings for both client and data center segments beginning in 2023’

The key phrase here is ‘core of Intel’s compute offerings’. It could be interpreted in two ways: at the core of a CPU design is a CPU core, which would mean an x86 design unless Intel were to skew away from x86 (unlikely). The other alternative could be an IO chiplet, which is also a ‘core part’ of a compute offering. Paul Alcorn from Tom’s Hardware has confirmed from Intel that the key element here is ‘compute cores’, and although Intel hasn’t specifically said the ISA of those cores, we are set to believe that Intel does indeed mean x86.

This means that other foundries will have access to the floorplans of Intel’s x86 designs, which used to be a big no-no at Intel. Now in saying that, foundries often have strict NDA requirements that stop them sharing designs with customers, as you might expect, but it’s the fact that Intel is even letting another foundry build x86 cores that is the highlight of this announcement.

All-in-all, Pat Gelsinger is enabling a roadmap that allows Intel to pivot, and pivot hard. Steering the Intel behemoth is difficult at the best of times, however Pat’s arrival and enthusiasm has certainly made the company more comfortable in finding where its next generation of revenue is coming from.

    So unless I'm misreading, none of this sounds like customers can use physical IP for an Intel x86 core on a third-party foundry - just that Intel is likely to do so itself. Is there something I'm missing that says otherwise?

    We won't know exactly until they disclose the exact licensing model, but you are likely correct.

    If only intel did this when the PS4 was being designed, the cpu cores wouldn't have been slow.

    "cpu cores wouldn't have been slow."

    these days the 'compute' area of the cpu is, what, 10% of the real estate? perhaps Dr. Cutress has some exact figures, but I'd wager it's been at least 2 decades since increasing transistor budgets were used for anything other than bringing off-cpu functions onto the chip. I guess that's progress of a sort, but also an implementation of monopoly. will ARM go down some different road? only The Shadow knows.

    Console vendors pretty much always go with whatever CPU vendor is offering the best deal that comes remotely close to meeting their requirements. That's why everyone went with IBM in the Wii/360/PS3 generation and the last two have been AMD for MS & Sony and NVidia for Nintendo. Though there were a lot of rumors around MS going with Intel this generation early in the XSX development cycle, and that might well have happened if Intel 10nm hadn't been delayed so much.

    i think with compute cores they mean their gpu stuff. it’s where intel manufacturing has had far bigger troubles, and would mean not giving away their x86 core designs. Also in the consumer space about half of the cpu die is dedicated to the gpu.

    The Goal is not only business motive but also political

    This mean, there will be new solution for cutting edge process node from US, not all is depend on Asian foundery

    Is this a joke ? Last time Itanium failed when Gelsinger was at Intel. This guy is really not Andy Grove to learn from mistakes but he is actively trying to net more cash. Again.

    x86 IP licensing LMAO. AMD and Intel are able to stronghold it because they are only ones in the game. What makes Intel think that x86 licensing to other fabless corporations will make them big ? And on top this is not ARM type IP where the IP owner is having no business in the core products except licensing. So this creates friction no matter how you see it. How can a company produce and create same stuff in its core business and also sell the same shit ? This just seems desperation that someome comes to Intel and buys their IP plus Fab capacity to build chips (think Surface garbage or a Console with new pathetic big little bs)

    IFS, what is this bullshit. Intel 10nm still has to prove itself. With 11700K GN review it's clear that RKL is a DOA product. And their new Cypress Cove bs is all smoke. Its worse than Skylake damn it. 10700K beats it due to Clock boost as AT also showed there's clock regression in scaling. So who is even trusting Intel x86 uArch AND their fabs ? 14nm++ is a feat but its old. Impossible to compete now with TSMC 7N forget 7N with EUV. 5N EUV is havoc.

    Next generation revenue lmao. Intel fucking needs to get their head straight. Which is getting Xeon on Track vs EPYC. And bringing competition back to HEDT and Mainstream. This whole thing smells so fake and random.

    They are done. Once Zen 4 drops Intel is going to cough blood. And their Xe GPU is even more shame. We saw how EMIB worked out. AMD Vega based APU. Now Foveros as if they are first.

    Just watch AMD with Xilinx FPGA plus RDNA and Zen will destroy this pathetic corp. Shame really how far they have fallen. I expected a 7nm design breakthrough not some merchant business.

    They'll be fine as long as AMD can't produce more.
    They have some important products in 2021 to keep them afloat in some markets: Ice Lake-SP, Tiger Lake-H and Alder Lake-S. With the latter they'll retake leadership in I/O (PCI-E 5.0 and DDR5).
    By the time AMD becomes a threat in production capacity, Intel might be back on track technologically.
  • duploxxx - Wednesday, March 24, 2021 - link

    With the latter they'll retake leadership in I/O (PCI-E 5.0 and DDR5).

    those chips will be capable of... not said when they will release with that spec... and what good is having I/O on par with AMD... knowing that the core can't follow...
