At some point people will use an LLM to design an Apple M series competitor.

Production grade CPU design is more than just the RTL (the source code.) To achieve the performance numbers that these companies get, you have to do a ton of optimization in your physical design to achieve the power/performance/area (PPA) metrics that make these products competitive. LLMs are not suitable for that kind of work.

There are people working on PPA optimization and trying to shake up how things are done, just not with LLMs.

Something that I think is fascinating, though, is that labs are no longer beholden to the limitations of commercial design software. Want to replace your simulator and optimizer with a fully custom verifiable stack of Lean proofs of optimality and correctness? Just throw your unlimited token budget at it.

I don't work in the business, but my understanding was that even with these companies' budgets, it's still too expensive to do any kind of verified performance optimality.

And I think correctness for anything near the size of a CPU is off the table.

Isn't that weird? The full knowledge of how to make such chips may one day be accessible to anyone, yet only the entrenched companies will remain the makers.

If we imagine machines being able to do the full process end-to-end, and the quality of that process only dependent on capital spent on tokens, I don't see how new companies could ever enter the market.

And be super-bankrupted by patent litigation from Apple. I don't think they're worried.

After all, they successfully threatened Adobe with spurious patent litigation unless they joined w/ apple in illegally fixing wages.

You don't think a criminal like apple would absolutely decimate any competition given the opportunity? They didn't hold back when it was a unambiguous crime, they surely wouldn't if it was merely bad for the world.

It is probably doable right not to push a risc-v design into that performance space.

They won't, because they'd need an ARM architecture license.

Qualcomm have an architecture license and the Snapdragon X2 Elite Extreme X2E-96-100 isn't too far off the M5 Pro.

Are they using LLMs to close that gap, or is this their Nuvia acquisition doing the heavy lifting?

Why, the LLM can make up its own architecture.

The value lies in the design space exploration, which is what an LLM can easily do.

Arm sells architecture licenses to anybody these days.

I mean you can design anything without a license. Selling it is where the problems come up. Even then there are likely places in China that would still make it for you.

Or they'll just build a competitor in RISC-V instead and that's fine.

Except the problem is not restricted to the actual ISA or its HDL implementation, etc.

It's even just getting space / time in a fab at that advanced of a process node.
