  • Yeah. I don’t believe market value is a great indicator in this case. In general, I would say that capital markets are rational at a macro level, but not micro. This is all speculation/gambling.

    I have to concede that point to some degree, since i guess i hold similar views with Tesla’s value vs the rest of the automotive Industry. But i still think that the basic hirarchy holds true with nvidia being significantly ahead of the pack.

    My guess is that AMD and Intel are at most 1 year behind Nvidia when it comes to tech stack. “China”, maybe 2 years, probably less.

    Imo you are too optimistic with those estimations, particularly with Intel and China, although i am not an expert in the field.

    As i see it AMD seems to have a quite decent product with their instinct cards in the server market on the hardware side, but they wish they’d have something even close to CUDA and its mindshare. Which would take years to replicate. Intel wish they were only a year behind Nvidia. And i’d like to comment on China, but tbh i have little to no knowledge of their state in GPU development. If they are “2 years, probably less” behind as you say, then they should have something like the rtx 4090, which was released end of 2022. But do they have something that even rivals the 2000 or 3000 series cards?

    However, if you can make chips with 80% performance at 10% price, its a win. People can continue to tell themselves that big tech always will buy the latest and greatest whatever the cost. It does not make it true.

    But the issue is they all make their chips at the same manufacturer, TSMC, even Intel in the case of their GPUs. So they can’t really differentiate much on manufacturing costs and are also competing on the same limited supply. So no one can offer 80% of performance at 10% price, or even close to it. Additionally everything around the GPU (datacenters, rack space, power useage during operation etc.) also costs, so it is only part of the overall package cost and you also want to optimize for your limited space. As i understand it datacenter building and power delivery for them is actually another limiting factor right now for the hyperscalers.

    Google, Meta and Amazon already make their own chips. That’s probably true for DeepSeek as well.

    Google yes with their TPUs, but the others all use Nvidia or AMD chips to train. Amazon has their Graviton CPUs, which are quite competitive, but i don’t think they have anything on the GPU side. DeepSeek is way to small and new for custom chips, they evolved out of a hedge fund and just use nvidia GPUs as more or less everyone else.



  • I have to disagree with that, because this solution isn’t free either.

    Asking them to regulate their use requires them to build excess capacity purely for those peaks (so additional machinery), to have more inventory in stock, and depending on how manual labor intensive it is also means people have to work with a less reliable schedule. With some processes it might also simply not be able to regulate them up/down fast enough (or at all).

    This problem is simply a function of whether it is cheaper to a) build excess capacity or b) build enough capacity to meet demand with steady production and add battery storage as needed.

    Compared to most manufacturing lines battery tech is relatively simple tech, requries little to no human labor and still makes massive gains in price/performance. So my bet is that it’ll be the cheaper solution.

    That said it is of course not a binary thing and there might be some instances where we can optimize energy demand and supply, but i think in the industry those will happen naturally through market forces. However this won’t be enough to smooth out the gap difference in the timing of supply/demand.


  • It’s a reaction to thinking China has better AI

    I don’t think this is the primary reason behind Nvidia’s drop. Because as long as they got a massive technological lead it doesn’t matter as much to them who has the best model, as long as these companies use their GPUs to train them.

    The real change is that the compute resources (which is Nvidia’s product) needed to create a great model suddenly fell of a cliff. Whereas until now the name of the game was that more is better and scale is everything.

    China vs the West (or upstart vs big players) matters to those who are investing in creating those models. So for example Meta, who presumably spends a ton of money on high paying engineers and data centers, and somehow got upstaged by someone else with a fraction of their resources.



  • I would say yes, because as is the real niche communities dont have the size for larger discussions.

    Mainstream communities e.g. about global news already have a decent size. And in many ways it doesn’t make much of a qualitative difference if there are 500 or 10.000 predictable comments. But many smaller communities are still mostly propped up by a few power users providing the majority of content which is not ideal for many reasons.




  • Existing one or on a topic of my choice?

    If I had to teach an existing one it would probably be sport, since as a reasonably fit person with a decent understanding on how to train in a healthy way it would probably be the one where I could come closest to providing a similar level to a real teacher. Otherwise maybe sociology? Think I could do a decent job there aswell.

    If I could make my own it would probably be personal finance. Because I think here in Germany education on this topic is basically non existent. And there is so much money wasted on bad financial products and wrong decisions, that giving everyone some basic lessons would have a huge positive effect.

    I never really understood the purpose of the XPS line anyway.

    The issue here is that you are comparing it to their business lineup, while it was a consumer product.

    Dell XPS (“Extreme Performance System”) is a line of consumer-oriented laptop and desktop computers manufactured by Dell since 1993.

    My understanding is that it was their premium consumer line sitting above the more entry level Inspiron line.

    Imo this kind of shows the basic problem with the xps line. As I understand it it was basically the premium consumer line, not something meant for business use. Meaning it had the nice specs on paper, but not the durability you’d need in a setting with extensive use and where downtime means serious money. But as you demonstrate this distinction was too blurry.


  • Yeah, sadly everything has to sound fancy. Imo this is partially to blame on consumers, but I do wonder how much of it is basic psychology vs induced demand that could be reversed if a company would stick with sensible product names for a while.

    Instead of basic they could also go with something like “essential” or “home” that maybe have slightly less negative associations.




  • Trying to do 10nm without EUV was a forgivable error

    How so? Literally no one uses EUV for 10nm and this wasn’t the problem. Isn’t SMCI even pushing DUV toproducing 5nm?

    My limited understanding is that they were too ambitious with e.g. using cobalt interconnects and at the same time had the issue that they tied their chip designs to specific nodes. Meaning that when the process side slipped they couldnt just take the design and use it on a different node without a lot of effort.

    Also I think they were always going to lose apple at some point. With better products they might have delayed it further. But apple fundamentally has an interest in vertical integration and control. And they were already designing processors for their phones and tablets.
