Do you see that thing Battle Frankie posted after last week's episode?

Which one?

A lot of people post a lot of things on there.

The normalized human time when you like compare one clock cycle in a CPU at three gigahertz

to like one second of real world time.

Yeah, that thing was very eye opening, let's say.

I did not.

Like I knew.

I understood this. I thought, but this illustrates

it in the best way I've ever seen. Yeah, I do all that stuff intuitively, but to see it quantified

is a very different thing. Won't you explain exactly what we're talking about here? Yeah, it's hard to

understand, like, what a nanosecond, how a nanosecond relates to say a microsecond, right? So on a 3 gigahertz clock cycle, one clock cycle takes about 3 tenths of a nanosecond.

So that's 310 billionths of a second, I guess.

And if you normalize that to one second, then accessing the level one cache of the one that's built into the CPU takes three seconds.

The level two cache takes nine seconds.

And the level three cache takes 43 seconds, which is bonkers.

Like that's the big thing that we were talking about on the chiplet that holds the whole thing together.

Accessing RAM, which takes between 70 and 100 nanoseconds, depending on the clock speed and latency, your RAM, would be equivalent to 3.5 to 5.5 minutes.

So it's like, that was the part where my eyes flew wide open.

Like the cash stuff makes sense.

It's like, yeah, okay, sure, the level three cache is going to take a good number of clock cycles to

because that's the slowest one, of course.
