Nehalem Cores

[ASH1982]

Just been reading up on the Penryn chips that are hopefully going to be coming out soon... July I think you guys on here said

Anyway stumbled across the Nehalem name but the article didnt give much more info on them. There are a few other articles on the internet but with allot of conflicting info in them.
Some say 45nm others 35nm... most seem to point to a possible 8 cores

Anyone got anything more concrete on this?

Nehalem is going to be the next architecture that is to succeed the current Core architecture. Its going to be 45nm. It is apparently going to have a integrated DDR3 memory controller aswell. Its expeced to ship mid 2008.

The 35nm stuff is code named Westmere at the moment. This is just a version of Nehalem not a new architecture. Which is expected some time in 2009. The successor to Nehalem will be Sandy Bridge (or Gesher as it used to be known).


Most info of it can be found on Wiki, the site that begins with H, Mikeshardware

wow I so dnt get how Intel can think that far ahead technology wise

That's usually because the technology is there already. It takes a lot of time to brand, manufacture, package and distribute 100,000s if not millions of chips at a decent price.

32nm is the next reduction after 45nm - but as mentioned its 2009 at the earliest. IMO its unlikely we'll see nehalem mid 2008, best guess is Q4'08 - fingers crossed.

They're marketing this Tick-Tock strategy atm, die-shrink followed by process improvement. It's worth a google if you're interested.

I think they are aiming for a die shrink every year and new acrhitecture every two years.

"The principle of cadence is based on what Intel calls the “tick-tock” model of silicon and microarchitecture that delivers a common processor architecture across all volume market segments. Each “tick” represents the silicon compaction beat rate, which has a corresponding “tock” representing the design of a new microarchitecture delivered in a cycle approximately every two years. Intel’s design methodology and its tremendous discipline are cornerstones of its principle of cadence, which has enabled Intel to deliver innovation in processors and platforms above and beyond the capabilities of the individual products."



i.e. ticks = die reduction, tocks = microarchitecture

hth.

ATM? Surely you mean since forever??

Moore's Law is effectively one of the best marketing stratagies ever!

I couldn't agree more - but I think their T/T strategy was just some new way to intimidate AMD. As in, we're ahead now, and have a strategy (read: marketing campaign) to keep going forward.

I know its o/t, but I really hope AMD can keep going - and I say that having never owned an AMD cpu. They're leaking money at an appalling rate right now, but goodness knows they've been great for competition.

I read a while ago that Nehalem will also see a reintroduction of Hyperthreading, not sure how true it is though?
