Google's real moat isn't the TPU silicon itself—it's not about cooling, individual performance, or hyper-specialization—but rather the massive parallel scale enabled by their OCS interconnects. To quote The Next Platform: "An Ironwood cluster linked with Google’s absolutely unique optical circuit switch interconnect can bring to bear 9,216 Ironwood TPUs with a combined 1.77 PB of HBM memory... This makes a rackscale…

100 times more chips for equivalent memory, sure.

Also, Google owns the entire vertical stack, which is what most people need. It can provide an entire spectrum of AI services far cheaper, at scale (and still profitable) via its cloud. Not every company needs to buy the hardware and build models, etc., etc.; what most companies need is an app store of AI offerings they can leverage. Google can offer this with a healthy profit margin, while others will eventually run out of money.

Earlier quoted context omitted.

Not very. Those fabs are vulnerable things, shame if something happens to them. If China attacks, it would be for various other reasons and processors are only one of many considerations, no matter how improbable it might sound to an HN-er.

What if China becomes self-sufficient enough to no longer rely on Taiwanese Fabs, and hence having no issues with those Fabs getting destroyed. That would put China as the leader once and for all.

First, the US has advanced fab capabilities and in case of a need can develop them further. On the other side, China will suffer a Russia style blockback while caught up in a nasty war with Taiwan.

Totally possible, but the second order effects are much more complex than "leader once for all". The path for victory for China is not war despite the west, but a war when the west would not care.

I think it's not about the cost but the limits of quickly accessible RAM

This is the “Microsoft will dominate the Internet” stage. The truth is the LLM boom has opened the first major crack in Google as the front page of the web (the biggest since Facebook), in the same way the web in the long run made Windows so irrelevant Microsoft seemingly don’t care about it at all.

Exactly, ChatGPT pretty much ate away ad volume & retention if th already garbage search results weren't enough. Don't even get me started on Android & Android TV as an ecosystem.

How much of current GPU and TPU design is based around attn's bandwith hungry design? The article makes it seem like TPUs aren't very flexible so big model architecture changes, like new architectures that don't use attn, may lead to useless chips. That being said, I think it is great that we have some major competing architectures out there. GPUs, TPUs and UMA CPUs are all attacking the ecosystem in different ways which is what we need right now. Diversity in all things is always the right answer.

A question I don't see addressed in all these articles: what prevents Nvidia from doing the same thing and iterating on their more general-purpose GPU towards a more focused TPU-like chip as well, if that turns out to be what the market really wants.

Deepmind gets to work directly with the TPU team to make custom modifications and designs specifically for deepmind projects. They get to make pickaxes that are made exactly for the mine they are working.

Everyone using Nvidia hardware has a lot of overlap in requirements, but they also all have enough architectural differences that they won't be able to match Google.

OpenAI announced they will be designing their own chips, exactly for this reason, but that also becomes another extremely capital intensive investment for them.

This also doesn't get into that Google also already has S-tier dataceters and datacenter construction/management capabilities.

> It is also important to note that, until recently, the GenAI industry’s focus has largely been on training workloads. In training workloads, CUDA is very important, but when it comes to inference, even reasoning inference, CUDA is not that important, so the chances of expanding the TPU footprint in inference are much higher than those in training (although TPUs do really well in training as well – Gemini 3 the prim…

I think it’s the same reason windows is inportant to desktop computers. Software was written to depend on it. Same with most of the software out there today to train being built around CUDA. Even a version difference of CUDA can break things.

With its AI offerings, can Google suck the oxygen out of AWS? AWS grew big because of compute. The AI spend will be far larger than compute. Can Google launch AI/Cloud offerings with free compute bundled? Use our AI, and we'll throw in compute for free.
