For how long exactly were Pentium, Core, and i# each out on non-extreme performance laptops?

How long were each of these in "non-extreme performance" laptops for? I say "non-extreme performance" laptops because I know extreme performance laptops are updated with the newest CPUs right when intel releases them, while "non-extreme performance" laptops may take a while (just like how macbooks are still using core 2 duo)

So, for example, what year/month did they start appearing in these laptops and what year/month did the next type of processor start replacing the previous type?

I have no idea how long Pentium was out for..
I thought Core was out for a year, then Core Duo for a year, then Core 2 Duo for 2 years (EDIT: actually, maybe core and core duo were both half years, i can't remember??)
I felt like i# has only been out for less than a year.. and already Huron River is to replace it in January 2011.

Please give me a history lesson on the CPU time-line!

 

They're out now. The Acer Aspire 5740g is one. There are lots. From Ultra portables to Desktop replacements.

 

Core i has been out since January. Originally we were supposed to see 45nm Nehalem dual core cpu's for notebooks in fall 2009, followed by the 32nm dual core cpu's we have now. Due to the economy Intel skipped the 45nm dual cors and made us wait until January when they launched the current 32nm dual coreCore i's/Pentium/Celeron for notebooks. Yes Sandy Bridge cpu's on the Huron River platform are fast approaching, but that is only because notebooks have had a shorter time span with the dual core Nehalem generation than should have.

 

Umm, Clarksfield?

 

I was talking about the cancelled 45nm Auburndale. But yeah, the quad cores slipped my mind for a second. Maybe they are the only the only notebook processors that stayed on schedule.

 

It was clearly inaccurate as-is; you should have said 45nm dual-core Nehalem.

 

so.. im guessing (and everything i'm typing is pure speculation) that core i was available for desktops in 2009 sometime, but they were only introduced into laptops in january of 2010? so basically they extended the lifespan of core 2 duos longer because of a poor economy, and since by january 2010, the economy was getting better and due to competition from amd, they decided to skip to the processor that would have been released at this time if it werent for the economy?

another question, if core i was supposed to be introduced in Q4 of 09, then doesnt that go against intel's "2 year" lifespan of their microarchitectures? was core i meant to have an abnormally short lifespan even if it werent for the economy?

Where did you read that? The first Nehalem CPUs (the desktop Bloomfields) were released in November 2008. The first mobile CPUs (Clarksfield) came out in September 2009. There wasn't anything new released in April 2009 unless you want to count demo samples (which exist for Sandy Bridge even now).
