Isn't their primary concern latency? I doubt a few GHz boost would do anything for them.

Depends on how low the latency already is. If you're already <0.5ms away network wise then perhaps shearing off 0.1ms from a 1ms operation could make a significant difference.

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…

Buying it at inflated prices from Intel effectively rewards them for their inability to produce more. That seems like the wrong incentive to set.

you have no idea how chip manufacturing works, do you? :) its a gamble for them to get such chips

> its a gamble for them to get such chips

Hardly, since the "rejects" will just be sold as the regular model(s).

In the old "lottery" system the rejects would end up on the secondary market, making Intel's final revenue effectively the same as if extreme overclocking wasn't a thing.

Also some types of HFT don't rely on network latency at all, it can be based on other factors.

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…

Specialist retailers and integrators have been super-binning chips for years. Intel are just taking a piece of that pie.

Or, more charitably, they are integrating that. In some industries, these high binned chips are a crucial competitive advantage, and I don't see any reason why they shouldn't validate the performance of each chip they sell (at least in HEDT, other product lines I can see having little or negative return from an approach like that).

Maybe they could even just make it explicit for all their products: market them by die type, configuration, and peak stable base clock.

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.

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

It's not so bad if you think of it more like a folding desktop that can occasionally be transported from place to place. The total weight is a lot less than a mini-itx chassis and a standalone 20" class monitor... But not by much.

Where are these chips going to actually end up? Gamers with more money than sense?

Binned & overclocked i9-9980XE’s are already available though. I’m honestly at a bit of a loss to understand Intel’s latest offering. But hey, it made us stop laughing about 10nm for a few minutes.
