I found this in the new Elektor magazine advert:
"A 4004 microprocessor from 1971 consists of 2,000 transistors.
Current Itanium series processors contain more than 3,000,000,000.
Around 65 years since the transistor was patented (1947)...
I remember...
We've come a long way, eh. I read that the ARM6 processor only has about 35K transistors. I've always wondered about the AVRs but haven't found anything very authoritative. With a µC, it'd be nice to see the memory and peripherals broken out.
