Is there a way in which this is good for a segment of consumers? When the current gen of GPUs are too old, will the market be flooded with cheap GPUs that benefit researchers and hobbyists who therwis would not afford them?
- wmf 11mo agoMany researchers and hobbyists cannot even plug in a 10 KW 8 GPU DGX server.
- CamperBob2 11mo agoThat doesn't exactly bode well for the EV revolution, then, does it?

- LogicFailsMe 11mo agoThe average commute in the United States is about 24 miles a day round trip. That's about 10 kWH. That's enough to charge overnight on a 15A circuit.
- CamperBob2 11mo agoYou can drive around with 24 miles of charge, but ... I'll pass, thanks. In reality, if you have a dryer outlet, you have a good fraction of 10 kW available.
- LogicFailsMe 11mo agoI just put in a dedicated 50 amp circuit myself and my car charges from ~25% to full in about 6-7 hours. But I wanted to present the lazy worst case scenario. The warrior's FUD here is that there isn't enough easily available lithium for everyone in just California alone to have one.
- BuffaloEric33 11mo agoAlmost all home EV charging is <=10kW.
- quickthrowman 11mo agoWhy not? It’s 40A at 240V, or 25% of the continuous load rating of a 200A 240V single-phase service. If someone can afford an 8 GPU server, they should be able to afford some #6 wire, a 50A 2P breaker, and a 50A receptacle. It has the same exact power requirements as an L2 EV charger.
- knollimar 11mo agoYou probably run a bigger (perhaps double) neutral and care about a stronger ground. But yeah, the $12 is rounding error at this scale
- quickthrowman 11mo agoIn the US, you don’t need a neutral for a 240V 50A circuit on a residential single-phase service, there are two line conductors (120V to ground) both connected to a 2-pole single-phase breaker, line-to-line between the two is 240V. You would need a neutral if it was a 208/120V three-phase service. Neutrals and grounds are sized per the NEC, neutrals are the same size as the line conductors and equipment grounds are sized off of a table. #6 conductors and #10 ground is what the NEC calls for.
- knollimar 11mo agoI just haven't seen server rooms that don't demand a doubly sized neutral when one is required. I live the NYC 208V life doing mostly resi, though. Quick search of the spec for that is 6 power supplies, 2 of which are redundant. Looks to use a neutral to me. Says it uses C19/C20 connectors edit: wait most ranges use 14-50R outlets and need a neutral ran. I am calling your statement into question. Surely harmonics and 120V internal draws cause non-zero neutral current. And I'm sure GPUs have harmonics being semiconductor flavored.
- quickthrowman 11mo agoTurns out you are correct on both points! My bad, NEMA 14-50R is a 4-wire receptacle with a neutral. I learned something new today, 200% neutrals are not required by the NEC but can help with non-linear loads, and certain transformers that mitigate harmonics need 200% neutrals.
- ares623 11mo agoSome of them will probably be starving, homeless, or bedridden by the time that happens but yes they can get cheap GPUs
- stego-tech 11mo agoUnlikely, for a few reasons: * The GPUs in use in data centers typically aren’t built for consumer workloads, power systems, or enclosures. * Data Centers often shred their hardware for security purposes, to ensure any residual data is definitively destroyed * Tax incentives and corporate structures make it cheaper/more profitable to write-off the kit entirely via disposal than attempt to sell it after the fact or run it at a discount to recoup some costs * The Hyperscalers will have use for the kit inside even if AI goes bust, especially the CPUs, memory, and storage for added capacity That’s my read, anyway. They learned a lot from the telecoms crash and adjusted business models accordingly to protect themselves in the event of a bubble crash. We will not benefit from this failure, but they will benefit regardless of its success.
- LogicFailsMe 11mo agoGPUs age surprisingly gracefully. If a GPU isn't cutting edge, you just tie two or more of them together for a bit more power consumption to get more or less the same result as the next generation GPU. if there's ever a glut in GPUs that formula might change but it sure hasn't happened yet. Also, people deeply underestimate how long it would take a competing technology to displace them. It took GPUs nearly a decade and the fortunate occurrence of the AI boom to displace CPUs in the first place despite bountiful evidence in HPC that they were already a big deal.

- LogicFailsMe 11mo agosource: Nvidia Shields still shipping with Maxwell GPUs from 2014 and many university labs still running on Pascal GPUs from 2016. But stupid facts don't matter, this one hit you wrong in the feels, amIRight?
