At this scale and volume, it's not really about good faith.
Changing fabs is non-trivial. If they pushed Apple to a point where they had to find an alternative (which is another story) and Apple did switch, they would have to work extra hard to get them back in the future. Apple wouldn't want to invest twice in changing back and forth.
On the other hand, TSMC knows that changing fabs is not really an option and Apple doesn't want to do it anyway, so they have leverage to squeeze.
At this level, everyone knows it's just business and it comes down to optimizing long-term risk/reward for each party.
Apple has used both Samsung and TSMC for its chips in the past. Until the A7 it was Samsung, A8 was TSMC, and the A9 was dual-sourced by both! Apple is used to switching between suppliers fairly often for a tech company; it's not that it's too hard for them to switch fab, it's that TSMC is the only competitive fab right now.
There are rumours that Intel might have won some business from them in 2 years. I could totally see Apple turning to Intel for the Mac chips, since they're much lower volume. I know it sounds crazy, we just got rid of Intel, but I'm talking using Intel as a fab, not going back to x86. Those are done.
But wasn't the reason they split with Samsung because they copied the iphone in the perspective of Jobs (to which he reacted with thermonuclear threats)?
They did had the expertise building it after all. What would happen, if TSMC now would build a M1 clone? I doubt this is a way anyone wants to go, but it seems a implied threat to me that is calculated in.
Job's thermonuclear threats were about Android & Google, not Samsung because Schmidt was on Apple's board during the development of Android.
> "I will spend my last dying breath if I need to, and I will spend every penny of Apple’s $40 billion in the bank, to right this wrong. I’m going to destroy Android, because it’s a stolen product. I’m willing to go thermonuclear war on this."
The falling out with Samsung was related, but more about the physical look of the phone
If Samsung (or any other fab) were to make Apple chips they wouldn’t learn anything that a good microscope couldn’t already tell them.
Samsung still makes the displays and the cameras for most iPhones. They continued to do business even while engaged in legal action. That they are still competitors wont stop them doing business when it suits them. Business doesn’t care about pride or loyalty; only money.
I believe just locking at a chip, does not enable you to to make such a chip, otherwise china would not be behind.
TSMC already makes them in their labs. They could tweak a few things, claim it is novel and just sell to the competition. (Apple would fight back of course with all they have and TSMC reputation would take damage)
Looking at a chip makes it easier, but it is still millions (or billions in the case of a CPU) of dollars for engineers to figure it all out. That doesn't get you to understand what was done or why so 2-3 years latter you can make that chip but they have now moved on to a faster/better version and you are behind. And of course if you try this Apple (or whoever you copy) will have plenty of engineers who can look at your chip and in just a few hours decide there is enough to have lawyers sue you for the copy.
China already has plenty of engineers who can make a chip, and experience with making CPUs. ARM licenses a lot of useful things for making a CPU (I don't know what). They would be better off in the long run making the chips they all ready understand better. Which is something they are doing. It takes longer and costs more, but because they understand they can also customize the next chip for something they think is good - if they are right they can be ahead of everyone else.
What China is lacking is the fabs to make a CPU. They have made good progress in building them, but there is a lot of technology that isn't in the chip that is needed to make a chip.
It took cerebras less than a billion to get to where they are now, CPUs are not that hard. You would probably be able to reverse engineer them for ~100 million
Doesn't seem likely, TBH. Nevermind the legal agreements they would be violating, TSMC fabs Qualcomm's Snapdragon line of ARM processors. The M1 is good, but not that good (it's a couple generations old by this point, for one). Samsung had a phone line of their own to put it in as well. TSMC does not.
At the end of the month, laptops with Intel's latest processors will start shipping. These use Intel's 18A process for the CPU chiplet. That makes Intel the first fab to ship a process using backside power delivery. There's no third party testing yet to verify if Intel is still far behind TSMC when power, performance and die size are all considered, but Intel is definitely making progress, and their execs have been promising more for the future, such as their 14A process.
>Apple has used both Samsung and TSMC for its chips in the past. Until the A7 it was Samsung, A8 was TSMC, and the A9 was dual-sourced by both!

This is false. Samsung competes with Apple on smartphones. Apple even filed a lawsuit against Samsung over smartphones.
Apple moved to TSMC because how can you trust someone to make chips for you containing your phone's core IP?
>I could totally see Apple turning to Intel for the Mac chips
I could totally see Apple will be wary turning their core IPs to Intel
TSMC holds the real power. Apple’s stability and Nvidia’s cash both matter but AI demand is distorting the entire semiconductor ecosystem. There are no easy exits. Building fabs, switching suppliers or waiting out the cycle all carry massive risk.
In the long run, competition (where via Intel, Samsung or geopolitical diversification) is the only path that benefits anyone other than TSMC
Trust comes first. That's why TSMC is a pure play fab. Unless there's something that can 100% guarantee protection for fabless players like Apple, no one will trust Samsung or Intel.
Fabless players' IPs are their entire business.
It'll be hard to trust Intel given Intel's past behavior, especially against AMD.
Anyone making a claim that trust will be 0% based on a single thing is obviously oversimplifying the situation. Trust is built on behavior, reputation, time, repeatability, etc.
Trust is subjective and relative.
If Alice doesn’t trust Eve, that doesn’t automatically mean that Bob doesn’t trust Eve. That usually requires both Alice and Bob to similar experiences or Bob must have a trust relationship with Alice.
Trust also changes over time. One CEO change and a company can change overnight thus causing all trust to evaporate. Normally CEOs are aware of this and don't change things and so trust transfers, but one mistake and you lose trust. It takes a lot to build back trust, but a few years of proving worthy of trust and it starts to come back. If your competitors violates trust in the mean time customers are more likely to risk you, and if you prove trustworthy the customers are likely to stay.
There are other factors than trust as well - the US government really wants intel fabs to take off and they may be applying pressure that we are not aware of. It could well be that Apple is willing to risk Intel because the US government will buy a lot of macs/iphones but only if they CPU is made in the US. (this would be a smart thing for the US todo for geopolitical reasons)
Does Apple spend R&D on iPhone screens like they do Apple Silicon? What's that got to do with what we're talking about regarding iPhone's core IP (Apple's own chip, the most important IP from Apple)?
> Does Apple spend R&D on iPhone screens like they do Apple Silicon
yes
> What's that got to do with what we're talking about regarding iPhone's core IP
The iPhone's core IP is iOS.
Collaboration on display and camera development leak major future milestones. Far more consumers care about cameras and displays than the CPU. Just like the camera and display the CPU IP is also protected by patents.

Apple is the company that just over 10 years ago made a strategic move to remove Intel from their supply chain by purchasing a semiconductor firm and licensing ARM. Managing 'painful' transitions is a core competency of theirs.
I think you’re correct that they’re good at just ripping the band-aid off, but the details seem off. AFAIK, Apple has always had a license with ARM and a very unique one since they were one of the initial investors when it was spun out from Acorn. In fact, my understanding is that Apple is the one that insisted they call themselves Advanced RISC Machines Ltd. because they did not want Acorn (a competitor) in the name of a company they were investing in.
PA, Intrinsity wasn't front of mind for me. My point is, Apple has proven they can buy their way into vertical integration, let's look at the history.
68K -> PowerPC, practically seamless
Mac OS 9 -> BSD / OS X with excellent backward compatibility
PowerPC -> x86
x86 -> ARM
Each major transition, biting off orders of magnitude more complexity of integration. Looking at this continuum, the next logical vertical integration step for Apple is fabrication. The only question in my mind, does Tim have the guts to take that risk.
Doesn't Apple have an ARM "Architectural License" arising from being one of the original founding firms behind ARM, which they helped create back in the 90s for the Apple Newton. That license allows them to design their own ARM-compatible chips. The companies they bought more recently gave them the talent to use their existing license, but they always had the right to design their own chips.
Not all of Apple‘s chips need to be fabbed at the smallest size, those could certainly go elsewhere. I’m sure they already do.
Is there anyone who can match TSMC at this point for the top of the line M or A chips? Even if Intel was ready and Apple wanted to would they be able to supply even 10% of what Apple needs for the yearly iPhone supply?
> Not all of Apple‘s chips need to be fabbed at the smallest size, those could certainly go elsewhere.
When I saw that TSMC continues to run old fabs, I immediately thought about this idea. I am sure when Apple is designing various chips for their products, they design for a specific node based on available capacity. Not all chips need to be the smallest node size.
Another thing: I am seeing a bunch of comments here alluding to Apple changing fabs. While I am not an expert, it is surely much harder than people understand. The precise process of how transistors are made is different in each fab. I highly doubt it is trivial to change fabs.
My understanding, and I’m a layman, is it basically requires making new masks. And that’s not trivial.
I guess you’d be doing that anyway with a brand new chip. But still probably easier to work with the tools/fab you know well.
I suppose you’d have to do it just switching nodes at TSMC. Which is why the A13 (or whatever) probably never moves to smaller nodes.
Sometimes Apple updates the chip in a product that doesn’t seem to need it, like the AppleTV. I wonder if it’s because the old node is going away and it’s easier to just use a newer chip that was designed for the newer node.
Apple knows first hand how difficult and expensive it is to fire your CEO, I mean chip fab, only to rehire them when its clear that decision didn't pan out.
I think this misses a key point. TSMC is leading edge. When Apple switched they were leading edge for pure play, but not far ahead of Samsung and certainly behind Intel. Now not only TSMC is the best, it is also the largest. Which means Apple don't have a choice.
It the old days the leverage was that without Apple, no one is willing to pay for leading edge foundry development, at least not enough money to make it so compared to Apple. Now it is different. The demands for AI meant plenty of money to go around. And Nvidia is the one to beat, not Apple any more. The good thing for Apple is that as long as Nvidia continues to grow, their order can be spilt between them. No more relying on single vendor to pus.
I would imagine they could split their orders between different fabricators; they can put in orders for the most cutting edge chips for the latest Macs and iPhones at TSMC and go elsewhere for less cutting edge chips?
presumably they already do that (since non cutting edge chip fab is likely to be more competitive and less expensive) so, given they are already doing that, this problem refers to the cutting edge allocations which are getting scare as exemplified at least by Nvidia's growth
It's ridiculous that a trillion dollar company feels beholden to a supplier. With that kind of money, it should be trivial to switch. People forget Nvidia didn't even exist 35 years ago. It would probably take like 3 to 5 years to catch up with the benefit of hindsight and existing talent and tools?
And anyway consumers don't really need beefy devices nowadays. Running local LLM on a smartphone is a terrible idea due to battery life and no graphics card; AI is going to be running on servers for quite some time if not forever.
It's almost as if there is a constant war to suppress engineer wages... That's the only variable being affected here which could benefit from increased competition.
If tech sector is so anti-competitive, the government should just seize it and nationalize it. It's not capitalism when these megacorps put all this superficial pressure but end up making deals all the time. We need more competition, no deals! If they don't have competition, might as well have communism.
There is a big waiting list for fab tools. You can't just spin that up out of nowhere. Modern chip fabs are the most complex things ever created, and till you spun up your own fab, supply and demand will have balanced out.
Also, how is nationalizing something pro-competition? Nationalized companies have a history of using their government connections to squash competition.
It can be interpreted a different way too. Apple is just a channel for TSMCs technology. Also the cost to build a fab that advanced, in say a 3 year horizon, let alone immediately available, is not one even Apple can commit to without cannibalising its core business.
I know you are maybe joking but I don't think the government nationalizing the tech sector would be a good idea. They can pull down the salaries even more if they want. It can become a dead end job with you stuck on archaic technology from older systems.
Government jobs should only be an option if there are enough social benefits.
I'm joking yes but as an engineer who has seen the bureaucracy in most big tech companies, the joke is getting less funny over time.
I've met many software engineers who call themselves communists. I can kind of understand. This kind of communist-like bureaucracy doesn't work well in a capitalist environment.
It's painful to work in tech. It's like our hands are tied and are forced to do things in a way we know is inefficient. Companies use 'security' as an excuse to restrict options (tools and platforms), treat engineers as replaceable cogs as an alternative to trusting them to do their job properly... And the companies harvest what they sow. They get reliable cogs, well versed in compliance and groupthink and also coincidentally full-blown communists; they're the only engineers remaining who actually enjoy the insane bureaucracy and the social climbing opportunities it represents given the lack of talent.
I'm going through a computer engineering degree at the moment, but I am thinking about pursuing Law later on.
Looking at other paths: Medicine requires expensive schooling and isn't really an option after a certain age and law, on the other hand, opened its doors too widely and now has a large underclass of people with third-tier law degrees.
Perhaps you can try to accept the realities of the system while trying to live the best life that you can?
Psyching yourself all the way, trying to find some sort of escape towards a good life with freedom later on...
Maybe consider patent law? I have a friend who worked for the patent office, and the patent office paid for their law school. Now they’re a patent attorney and doing quite well.
Bruh, with some very rare exceptions like valve, every company is run as a dictatorship or oligarchy. That goes beyond tech, hell big tech at least gives some agency to their engineers.
The only way you don’t need to be versed in compliance or group think at a US firm as an employee is to either be
1) independently wealthy, so your job is a hobby you can walk away from
2) have some leverage on a currently in demand skill, but the second that leverage evaporates they will demand the compliance
Also I realized I undersold it, they aren’t just run as dictatorships/oligarchies, they are usually run as command economies as well.
The whole capitalist competition style behavior only happens with inter firm interactions, not internal ones
Find a small company with a founder who loves their team and wants them to be happy. They exist, I assure you. They're not even rare.
I spent most of my career working in companies with <50 employees, and only hit a couple of unpleasant founders. The few large companies that I worked in were always bureaucratic nightmares by comparison.
Small companies won't pay FAANG salaries, but they also won't make you feel like a meaningless cog in a vast unsympathetic, unproductive, machine.
> I spent most of my career working in companies with <50 employees
I’ve worked for 3 companies like that. It was really great if your views aligned with the founder. If they didn’t, you got fucked.
I really enjoyed when a bunch of juniors were fired the day before Christmas because the founder heard them discussing the latest movies they watched and decided that they had bad opinions and shouldn’t work at his company since he’d be embarrassed if his peers heard their tastes. Not hyperbole, direct statements. We referred to it as the Red Christmas at the time.
I believe you got lucky, I don’t find your advice actionable.
>Please continue doing whatever you're doing now that is working for you
Lol.
It doesn't work out because I don't have leverage, and tried to stand up for what I believe in. I also don't believe it would work for you unless you had views that aligned with the current oligarchical leadership that the entire US industry is operating under.
If you only have a good time when you found the "right" founder, because they will and are capable of harming your career or income when you disagree with them, and the law does effectively nothing to protect you from their ego driven tantrums, then you are a serf at best.
I'd agree with you if it was relatively common that employees who had differences of opinions with founders of companies, weren't forced out, but that is not my experience.
I do not find contentment out of accepting that some assholes are my Betters because they have more money than me.
What is odd to me is hearing people talk as if somehow a job is supposed to be intrinsically enjoyable or enriching. Paid labor is and always has been a subservient role that pays exactly the minimum that the market allows for the circumstances.
Labor is the next option above slavery and indenture, and now that slavery and indenture are frowned upon, labor has absorbed that space as well.
If you want to have some control of your environment and destiny, you must be an independent agent, a contractor, entrepreneur, or consultant. A tradesman. You have special skills and expertise, your own tools, and a portfolio of masterpieces at the least.
There is nothing new in this space of human endeavour, it is as it has been, and I suspect will continue to be, for better or for worse. Sacrificing your agency for subservience is going to make you feel at the mercy of your “betters”. If you don’t want that, don’t do that. Labor law and other conventions have made it a little better, but the fundamental relationship is still master and servant.
> Labor is the next option above slavery and indenture, and now that slavery and indenture are frowned upon, labor has absorbed that space as well.
If we go down this path, what can I say that doesn’t get my account banned and my speech suppressed for what what I would suggest doing to people with your opinion?
We don’t have to go down that path, it’s the path we’re already on.
It’s not the way I think it -should be- but it is the way that it is. The incentive alignment keeps it at that local minima, and every attempt to move it to a new one so far has introduced so many perverse incentives that it ultimately causes the regression or even complete failure of the economies it is implemented in.
I don’t know what the answer is that maximises human happiness and minimises human misery, but I suspect it lies well outside of the paradigm of conventional market economics.
Within the dominant paradigm, It’s all a matter of risk management. With employment, you are paying your employer with your surplus value to handle the risks that you feel powerless to manage. Market risks, capital risks.
In exchange, you accept risks that your opinions and comfort won’t be prioritised, and in some cases even your physical well being.
In effect, you are betting against yourself being able to balance those risks against the risks posed by pursuing profitability.
The ability to manage risks is intersectional with your ability to manage discomfort and privation. When you run out of money, the house wins by default.
That’s why the foundational step for anyone should be to do whatever they must to obtain a safe fallback position. A place to be. A safety net. This is what enables risk accommodation. Without taking risk, there will be no advancement. If you don’t have a fallback plan, a safe spawn point, do everything in your power to create one, at least for your children.
> It would probably take like 3 to 5 years to catch up with the benefit of hindsight and existing talent and tools?
Are you talking about TSMC - because that is a single, albiet primary, node in a supply chain, that's also what you have to replicate. AMSL is another vital node.
So many people with "it's just a factory, how hard can it be". The answer is "VERY", as a few endavours have found out already - and they will probably find out even at TSMC Arizona.
I shall illustrate with Adrian Thompson's 1996 FPGA experiment at the University of Sussex.
Thompson used a genetic algorithm to evolve a circuit on an FPGA. The task was simple: get it to distinguish between a 1kHz tone and a 10kHz tone using only 100 logic gates and no system clock.
After about 4,000 generations of evolution, the chip could reliably do it but the final program did not work reliably when it was loaded onto other FPGAs of the same type.
When Thompson looked inside at what evolved, he found something baffling:
The plucky chip was utilizing only thirty-seven of its one hundred logic gates, and most of them were arranged in a curious collection of feedback loops. Five individual logic cells were functionally disconnected from the rest - with no pathways that would allow them to influence the output - yet when he disabled any one of them the chip lost its ability to discriminate the tones.
Pure Silicon Crystals for the wafer is another very specialist supplier you can't just decide to become - your local gravity will probably have an effect you need to tune into
>If tech sector is so anti-competitive, the government should just seize it and nationalize it.
Trump is using his DOJ to probe Jerome Powell with a bogus lawsuit because the Fed won't lower rates on demand.
An independent Fed is the most important body for the USA. Lowering rates should be based on facts, not dictated by some bankrupt casino CEO. And now you want our government to nationalize the tech sector?
I don't support nationalizing the tech sector, but I believe the reason we have Trump in the first place is because our government refused to nationalize health care.
