Have you ever wondered if the "big break-up" between Apple and Intel was actually just a long, dramatic break? Well, the rumor mill has been spinning lately with whispers that the tech giant might be crawling back to its old flame for future silicon. But before you start imagining an Intel-powered iPhone 17 or 18, industry insiders have a reality check that is colder than a liquid nitrogen cooling rig. In what is becoming a definitive "not gonna happen" moment, experts are claiming there is "zero chance" that Apple iPhone chips will leverage Intel’s advanced nodes.
Intel has attracted quite a bit of chatter over the past few weeks amid tantalizing prospects of Apple returning to the chipmaker's embrace for some M-series processors and non-Pro iPhone chips. However, a new perspective from industry insiders has largely precluded the possibility of Apple iPhone chips leveraging Intel's bleeding-edge nodes. The reason? It’s not about drama or politics—it’s about the laws of physics and a little something called "heat."
The Rumor: A 2027 Homecoming?
In recent weeks, both GF Securities and DigiTimes have disclosed that Apple might opt for Intel's 18A-P process for its lowest-end M-series chips that are expected to ship in 2027, as well as non-Pro iPhone chips in 2028. GF Securities also went a step further by noting that Apple's bespoke ASIC—expected to launch in 2028—will leverage Intel's EMIB packaging.
We even noted recently that Apple has already signed an NDA with Intel and procured PDK samples (Process Design Kits) of its advanced 18A-P process for evaluation purposes. Do note that Intel's 18A-P process is its first node to support Foveros Direct 3D hybrid bonding, which allows for stacking multiple chiplets through TSVs.
But as the saying goes, "looking at a sample" is not the same as "ordering a million units." Several industry insiders, while commenting on the SemiWiki forum, have poured cold water on Intel's hopes of manufacturing Apple iPhone chips. And at the heart of this despondent thesis lies the chipmaker's ill-fated decision to go all-in on Backside Power Delivery (BSPD) for its 18A and 14A nodes.
The Heat Problem: Why Your Pocket Can't Handle Intel 18A
Basically, unlike TSMC, which offers some nodes with BSPD and others without it, rounding out its overall offerings, Intel has gone all-in on BSPD for its bleeding-edge 18A and 14A nodes. This technology—which Intel calls PowerVia—is a marvel of engineering, but it has a major "Self-Heating Effect" (SHE) that makes it a nightmare for mobile devices.
What is Backside Power Delivery (BSPD)?
Performance Boost: It powers the chip via shorter, thicker metal paths on the backside, lowering voltage drop and allowing higher frequencies.
Transistor Density: By moving the power "plumbing" to the back, it frees up the front side for more logic, reducing wiring congestion.
The Catch: Chips made on Intel's advanced nodes will sport a degraded heat dissipation ability.
For a laptop (like a MacBook Air), you can manage this heat. For a phone that lives in your pocket and has zero fans, it's a different story. The requisite heatsink for a BSPD chip has to be kept around 20 °C cooler for the same die temperature in hotspots. This is because vertical heat spreading is bad in these designs, and lateral spreading is even worse since there's no thick silicon substrate to soak up the energy.
Geopolitical Tensions and the Global Supply Chain
The potential shift of Apple back to Intel isn't just a technical decision; it's a piece of a much larger puzzle involving international politics and geopolitical tensions. Currently, Apple is heavily dependent on TSMC in Taiwan. With the risk of international conflicts and the shifting sands of international trade, Apple is desperate for a "second source" of chips based on American soil.
The Macroeconomics of Silicon
Foreign Investment: The US government is pouring billions into Intel via the CHIPS Act to ensure economic growth in domestic semiconductors.
Supply Chains: Apple's supply chains are currently hyper-concentrated in East Asia. Diversifying to Intel’s Arizona fabs would be a massive strategic win for US macroeconomics.
Economic Sanctions: In a world of increasing economic sanctions and trade barriers, having a "Sovereign AI" chip manufactured in the USA is a major hedge against global instability.
Main Points: Why Apple is (Probably) Staying with TSMC
Thermal "Wall": The self-heating issues with PowerVia are currently a dealbreaker for the fanless, thin enclosures of iPhones.
Yield Concerns: While Intel is making progress, they haven't yet proven it can manufacture hundreds of millions of identical, perfect chips at the scale Apple requires.
TSMC Strategy: TSMC is taking a more cautious, "wait and see" approach to Backside Power, allowing them to refine the thermals before forcing it on mobile customers.
M-Series vs. iPhone: While the iPhone is a "no-go," the M-series Mac chips have a higher thermal ceiling, meaning Intel still has a foot in the door for future MacBooks.
Frequently Asked Questions (FAQ)
Q: Is Apple actually going to leave TSMC? A: Not entirely. They are likely looking at Intel as a "backup" or a second source to gain leverage in price negotiations with TSMC.
Q: Why did Intel choose PowerVia if it's so hot? A: Because for servers and high-performance desktops, it’s amazing. It solves a lot of power delivery problems that occur when you're pushing a chip to its absolute limits.
Q: What is a PDK? A: A Process Design Kit. It’s basically the instruction manual and digital tools a company like Apple uses to design a chip so that a factory like Intel can actually build it.
Q: Will the iPhone 17 use Intel chips? A: Highly unlikely. Most reports point toward 2027 or 2028 for any potential Intel-made Apple silicon, and even then, it would likely be for lower-end devices.
Conclusion: The Laws of Physics Win Again
At the end of the day, Apple's obsession with battery life and thermal efficiency is legendary. If a technology makes an iPhone feel like a hot potato in your hand, Apple won't touch it. Due to these troubling thermal issues, industry insiders believe that there is "zero chance" that Intel would get to manufacture Apple iPhone chips anytime soon.
While the economic repercussions of this are tough for Intel’s foundry dreams, the saga isn't over. Intel is betting the farm on 18A being the node that catches them up to TSMC. They might still win over the M-series Mac chips or even Apple's custom AI server chips, but for the device in your pocket? The "zero chance" verdict seems to be the final word for now.
