So only 2 cores. They forgot to say for how many microseconds can the chip sustain this speed.
And 400 A ? Per nanosecond or what ? Thank god it will mainly wait for I/O and has enough time to cool itself. /s
Amps are already over time — 1 amp is 1 coulomb (6e18 electrons) per second.

People have this weird view of modern chips. Yeah, they /can/ use a lot of power and produce a lot of heat.. Under terrible loads most people dont actually hit for any sustained period. even gaming, you arent going to be pegging all 24 cores.
EDIT: Just out of curiosity I looked up what voltage regulator slew rates for modern processors are, and it seems to be on the order of 100 A/µs, in case someone is interested.
A CPU that can hit 6ghz while pulling 400amps but can only do that for a few milliseconds before throttling itself is not particularly impressive.

This is exactly what you are saying, they are asking how long can it run at 6 GHz before they have to throttle. Then they continue with the sentence I originally responded to.
And 400 A ? Per nanosecond or what ?
I see mainly two possibilities. The first one is that they made a typo and what they actually wanted to write is »And 400 A? For one nanosecond or what?« which would essentially be repeating the exact same question as in the sentence before, just in terms of current instead of clock frequency.
But this is not what they wrote, they wrote »And 400 A? Per nanosecond or what?« which leads to the second possibility and the one I consider more likely. They were confused about the unit, the equivalent of responding to »The average US citizen consumes 10 kW of power.« with the question »Per day? Per month? Per year? In its lifetime?« which obviously makes no sense. That would be an appropriate response to the statement »The average US citizen consumes 89 MWh of energy.«
Without the author telling us, we will never know for sure, but I find it more likely that they were confused about the unit than that they repeated the exact same questions twice and made a typo in the second one that just makes it look like they were confused about the unit.
