Also notable for a huge increase in TDP from the next-slower model (255 W vs 165 W) - and it has four fewer cores. > Other details about the chip that we have learned include that it will have a listed TDP of 255W, which means the peak power will be higher. Motherboard vendors will have to support 420 amps on the power delivery for the chip (which at 1.3 volts would be 546 watts), and up to 30 amps per core.

TDP doesn't mean much at intel. Expect any performance chip to consume way more than TDP when fully loaded.

TDP is just a software setting at this point.

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…

Note that many businesses, and some circuits in residential homes, are wired for 20 amps. The sockets that definitely support 20 amps have an additional slot for 20 amp connectors. See: https://upload.wikimedia.org/wikipedia/commons/thumb/4/42/El...

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.

Older houses have interesting wiring. I've even seen a 5A circuit (once) in a really old place, varnished cotton clad copper wire and other interesting stuff.

Also (in NL), a fire that had started in a junction box that somehow died out without becoming more serious. That was a pretty scary find in a house that I had just bought.

This would be a pretty significant liability for builders in countries that have automatic consumer protections (eg: Consumer Guarantees Act in NZ). The builders would have to eat the costs of faulty units.

That means they probably won’t be sold there.

True, if that’s the cost of our consumer protections I’m okay with that. It’s actually really nice to live under. That said I’ve never been on the retailers end.

550+ watts is insane. That is spaceheater territory. Residential outlets start tripping at 1500-2000 watts. How soon we will have to run even basic gaming machines off multiple outlets.

There are gaming “laptops” available now that come with 2 power adaptors, as a single 330W is not enough to power the system under full load For now, they can be on the same circuit

There are e.g. 780W single units out there. Basically a PSU in a more convenient box. A little easier to pack up.

What this says to me is don't bother trying to super overclock a i9-9940X, Intel has already skimmed off the cream from that chip run. It seems kind of scummy, but I guess otherwise your rare stable overclock chip might end up in some boring business server where it will always run at stock clocks. I do note that Intel still wants nothing to do with overclocked chips in their warranty department, even when they did t…

That wouldn't make that much sense at that number given that such a large percentage of recent chips have been good enough to make it to 5.0 ghz+ according to these statistics recorded by Silicon Lottery: https://siliconlottery.com/pages/statistics -- no stats for i9-9990XE but there's enough to get an idea.

It wouldn't be that shocking if delays keep hitting on the new product line that they just skim the top 30% of chips and call it a "new" product though, which would be both really funny and almost immediately noticed. But overall this kind of thing is inevitable given the giant difference between what these kinds of processors run at stock and what people who are eager to buy a top of the line processor are actually going to want to run it at.

>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?

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, with the added bonus that they don't have to honor any warranty stuff since they're going to be clocked to hell.

Nobody is forced to take part in the auction. There are other CPUs that can be chosen from. If an auction participant calculates it pays for them to buy these even an inflated prices they are not really ripped off, it's just free market.

Also, binning of CPUs is a fact of life. CPUs don't all come the same from the production line. It allows you to buy bit less capable CPU for much cheaper if you wish so which, I would assume, you didn't take into consideration when you posted your thoughts.

255W 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 A…

Tom's Hardware has been doing excellent power consumption analysis for years and they measured the 2990WX with PBO (factory overclocking) enabled to consume 500W in torture loop. https://www.tomshardware.com/reviews/amd-ryzen-threadripper-...

I've lived in a few older homes, and have experienced some of this firsthand. My current home has some of that wire with porcelain wire nuts in the older circuits. Previously we lived in an earlier place that still had a small amount of legacy knob-and-tube wiring. (Bare copper wire kept off joists with porcelain insulators of various sorts.)

Never had to deal with fuses, or sub-10A circuits. (But the utility of a 5A household circuit seems evident in an older world where the whole-house service might be 30 or 60A.)
