Intel representative cant do maths

I was just reading the news and I came across this article about the new 45nm Intel Penryn.

Two-Storey building eh?

Well the gate size on the penryn is 45nm, and the chip is 107mm^2 (approx 1cm by 1cm).

If we look at what chips were in production 20 years ago (1987).

http://en.wikipedia.org/wiki/Microprocessor_Chronology

You'll see that a 1988 486 had a 1um gate size (1000nm).

So the gates were 22x bigger. So the die would be roughly 22cm x 22cm.

Hardly the size of a house

The Intel rep did his calculations on a Pentium 1 and it "rounded" the answer to the nearest 2 stories.

Everyone remembers the infamous Pentium math bug coverup, yes?

Heh, I have a vague memory of having to untick a box somewhere to get around it in Windows 98 SE.
