<p>Apple is about to deprecate the iphone 11/SE 2020 version. Am gonna repurpose them as webcams given the 12MP camera put in there is arguably better than the brand new ones they put on new macs.<p>The phone now has a limited lifespan though because of this prior stupidity where eventually am gonna get into spicy pillow territory. At that point the phone prematurely dies.<p>We are going into a period where we are throwing away devices with 12mp+ cameras, and processors arguably faster than most desktops. It was arguable when the phones were old and legacy, but at this point the cameras on there are stupidly good.<p>We need these phones to be repurposed for a second life and actually capture their manufacture energy costs.<p>Frankly, if Apple allowed old iphones to be used for server usage, it is kind of crazy how efficient per dollar that would be.</p>

<p>ARM is a bloody financial hand grenade.<p>10% of the stock is floated.<p>90% of the stock is owned by Masa who used it for collateral for his 18 billion loan for Stargate.

<p>Okay but even in that case the hardware suffers significant under utilisation which massively hits RoI. (I think I read they only achieve 30% utilisation in this scenario)</p>

<p>They worked out because there was an excess of energy and water to handle it.<p>We will see how the maths works out given there is 19 GW shortage of power. 7 year lead time for Siemens power turbines, 3-5 years for transformers.<p>Raw commodities are shooting up, not enough education to cover nuclear and SMEs and the RoI is already underwater.</p>

<p>Buy gold.<p>Current US debt to gdp is 124%, 38.6 trillion.
Japan too at 230-240%.<p>Bond markets in both are looking seriously unhealthy (Japan going via a Liz Truss moment at present).<p>If the AI bubble falls over, the US government is going to have to print 5 trillion to cover the bubble at least. The only option there is inflate away anyone holding cash.<p>If hte AI succeeds and people are replaced, the US government faces a massive fiscal cliff of a loss of tax receipts. They won't be able to service the debt and again will be forced to inflate away.<p>To service current debt projects, AI growth needs to return some 3.2-3.5%, it is currently 0.5%.<p>Bonds, equities, USD, and housing are all risk assets right now.</p>

<p>I think ARM is the one to watch. Softbank only has a 10% float of their stock.<p>90% of their stock is being used as collateral against 33 banks for 18 billion stargate loan to OpenAI.<p>Given Japanese bond markets right now, 30% circular financing, if the AI narrative falls, ARM is gonna blow up.</p>

<p>I am still a little skeptical about utilisation rates. If demand is so extreme, wouldn't we see rental prices for H100/A100 prices go up or maintain? Wouldn't the cost for such a gpu still be high (you can get em 3k used).</p>

<p>The cpu is what a 9950x whilst paired with one of the cheapest asus motherboards with underpowered VRMs according to games nexus, hardware unboxed.<p>The cooler was under the rated tdp of the platform. That and it lasted 6 months and so far seemed the only case of it falling over like it did.<p>Yea am leaning on it being user error.</p>

<p>The biggest discussion I have been on having this is the implications on Deepseek for say the RoI H100. Will a sudden spike in available GPUs and reduction in demand (from efficient GPU usage) dramatically shock the cost per hour to rent a GPU. This I think is the critical value for measuring the investment value for Blackwell now.<p>The price for a H100 per hour has gone from the peak of $8.42 to about $1.80.<p>A H100 consumes 700W, lets say $0.10 per kwh?<p>A H100 costs around $30000.<p>Given deepseek, can the price of this drop further given a much larger supply of available GPUs can now be proven to be unlocked (Mi300x, H200s, H800s etc...).<p>Now that LLMs have effectively become commodity, with a significant price floor, is this new value ahead of what is profitable for the card.<p>Given the new Blackwell is $70000, is there sufficient applications that enable customers to get a RoI on the new card?<p>Am curious about this as I think I am currently ignorant of the types of applications that businesses can use to outweigh the costs. I predict that the cost per hour of the GPU dropping such that it isn't such a no-brainer investment compared to previously. Especially if it is now possible to unlock potential from much older platforms running at lower electricity rates.</p>

<p>It should be trivially easy to reproduce the results no? Just need to wait for one of the giant companies with many times the GPUs to reproduce the results.<p>I don't expect a #180 AUM hedgefund to have as many GPUs than meta, msft or Google.</p>

<p>I think there can be a difference here.<p>Was looking recently at the power requirements of an amp + subwoofer + 5 5.1 JBL surround speakers.<p>The setup was done decade ago, and the power needed for it was nuts. Something like 500W for a Denon amp and 250W for a JBL subwoofer?<p>For reference something like a OG HomePod consumes what 45W? The Sony srs xg500 boombox can last 30hours and is a giant room shaking boombox.<p>The difference in power efficiency between these old and new setups are nuts. Nevermind compatibility with AirPlay, streaming etc…</p>
