I've never tripped an outlet on less than 2500 watts, and that was an old electrical network... Did I get lucky or do standards vary in different countries?
Most circuits trip on current, because I^2R heating is what causes fires in house wiring, 15A is relatively common, to get power you multiply by voltage which varies by country, in US that gives you 1800W and UK it’s 3600W. There are a ton of circuits which aren’t 15A though. If you live in UK, you might note that electric tea kettles work fine, but in the US they do not (they’re too slow). That’s the biggest practic…
It never occurred to me that the voltage difference between America and Europe/Asia would cause a corresponding differences in watt output given the same amps... But yes indeed, US kettles boil much slower.
Other appliances that require a lot of juice include vacuum cleaners, electric hobs, space heaters, portable ACs/dehumidifiers. So having something trip a living room circuit pulling just 2000 watts would drive me nuts in the long run

If you’re handy with electricity and don’t mind fracturing a few rules, European kettles work just fine on 240V 60Hz power. A British 13A plug in the kitchen is a nice conversation piece too. Note: because of the US “split phase” system, the neutral wire won’t be neutral anymore but rather 120v above ground. The kettle bases I’ve used are well designed, but do be careful.
Specifically to being careful: put a GFCI upstream of the kettle outlet. Which should be there anyway because it's a kitchen, but even more important with a phase-to-phase setup.

10 Amp 120V circuits are quite common in the US and Canada.
For what? I've never seen less than 15A in general premise wiring.

>It seems kind of scummy how is it scummy? is because intel's efficiently allocating those CPUs (via auction market), rather than randomly giving them out?
An economist might call it efficient, but most would call it greed
Most would call it completely fair, and a proper incentive to bring similar products to market.
It seems to me that greed is a problem affecting those who want it all, particularly luxury items, while complaining that they should be exempt from paying any cost.

> It's (a little bit) scummy, because they're selling them on auction, which has a decent chance of flogging them for orders of magnitude more than they'd ordinarily sell them for, It seems to me that demand is far higher than supply, thus the auction ensures that those who really want them will have a realistic shot of getting one. That's far better than having to resort to buying them from price-gouging scalpers.
Buying it at inflated prices from Intel effectively rewards them for their inability to produce more. That seems like the wrong incentive to set.

For this assertion to make any sense you'd need to believe that they don't benefit by increasing sales of a product line, particularly when they increase prices.

#58255W TDP for a single socket, holy shit, that pretty much demands a 280mm radiator size water cooling loop setup (2 x 140mm fans).
I kind of like this trend of power-hungry beastly CPUs. The AMD 2990WX is also rated 250W (but for 32c/64t@3GHz). I have one with a 280mm AIO, and it sees high 60C under load at stock frequencies. I can only overclock to 3.4GHz while sustaining heavy compute 24/7 and that's probably drawing close to 400W and heats up to mid 80C (in a room with 20C ambient). It's a pleasant space heater for the winter.
Hoping to see AMD continue to push the HEDT threshold. Let the server market have their underclocked power-efficient processors. Though to be honest if things go much further I'm going to need a custom waterloop next generation.

Where are these chips going to actually end up? Gamers with more money than sense?
HFT
I'm guessing the chance of an eventual calculation error is not worth the potential speed gains (though you could run those Pi calculators to check for CPU stability)
HFT is not so much about CPU speed but algorithmic optimization.
