Intel Larrabee set for release in 2010

Friday 22nd June 2007, 06:40:00 PM, written by Arun

Information Week reports that during a conference at their headquarters, Intel spoke to analysts and reporters about their future energy-efficient products, including Larrabee and wireless solutions. Justin Rattner, Intel's CTO, also noted that Larrabee will be their "first tera-scale processor" and that it is aimed at a 2010 release, or possibly 2009 if things go especially smoothly.

Justin also reiterated that Larrabee will deliver "well in excess" of one teraflop of processing power. The company stressed the importance of their "path finding" process: previously, product development engineers were pretty much on their own guessing what design decisions made the most sense for the target timeframe. In the company''s newest initiatives, such as Tera-Scale, researchers and product development people are working much closer together. The researchers are also responsible for finding "the best use for newly developed technology in products".

The fact that Larrabee (or presumably, its first silicon implementation, as the codename often seems to refer to the architecture and all its potential derivatives) seems now more likely to be released in 2010 (or very late 2009) rather than early 2009 brings up a number of interesting questions, such as what process it will be manufactured on and what NVIDIA and AMD's products will bring to the table in that timeframe.

In terms of process technology, the 32nm shrink of the Nehalem architecture (aka Westmere) is aimed at a 2H 2009 release, and most likely Q4. If Larrabee comes out after that, it would make sense to presume that it will also be manufactured on 32nm. Furthermore, if it wasn't, Intel would actually be at a process disadvantage in that timeframe: NVIDIA and ATI are likely to be on the 40nm half-node at TSMC, while Intel would only be on 45nm. As such, this question is of keen importance, as it will determine much of the future competitivity of the initial implementation of the Larrabee architecture.

However, given that Larrabee has been compared with Gesher (aka Sandy Bridge, which is a 32nm chip) in a recent Intel presentation, it is far from impossible to imagine it will be produced on the same process. Finally, in terms of competing products, this most likely implies that Larrabee will directly compete with NVIDIA and ATI''s true next-gen architectures, rather than with loose derivatives of the G80 and R600. No matter what these new architectures will be called (G100 and R800?), they will certainly be very different from today's, and that makes it much more difficult to predict how Larrabee will compare to the competition.

Found more info on Ct in http://blogs.intel.com/research/2007/09/ct_one_vision.htmlI bet in some days we will get a PDF from the IDF2007 with more specific informationAlso http://www.pcper.com/article.php?aid=453

Btw, I think they bought Havok to improve their upcoming physics and raytracing API.

Actully I belive they bought Havok to gain a strong foot hold in devloper relations.

It seems Intel said in the IDF2007 that gonna launch Larrabee as a "Workstation/server chip" by the middle of 2008:

You will *not* quote Fudzilla as a viable news source. Can someone add this to the rules please?

I'll add it right next to the one that says you will *not* make up senseless 'rules' and ask us to implement them.It's as if all common sense has left the world of technology enthusiasm sometimes. If you don't like Fudzilla, quietly choose to ignore the links and what's said about them, wherever possible. Don't force your news filtering agenda on everyone else.

Jeez, it was a joke.

Guess I forgot to add the smiley.

It's okay :) I agree with Rys though: fudzilla is not even bad enough to half-jokingly consider such a rule, IMO. In recent months, Fudo has had some interesting exclusives that turned out to be spot on, including one AMD exec resignation way before anybody else.

However, he's wrong more often than right by a fair bit AFAICT, and in that context it's important never to take what he writes with a *lot* of salt. But that doesn't mean it isn't worth linking to if related to the discussion at hand, imo...

it'll be interesting to see how the top-end Larrabee with the most cores compares to Nvidia G100 and AMD R800 in a variety of different games and graphical situations.

NV should be past G100 by then. G100 is a 2H 2008 product. Larrabee won't be out until '09 at the earliest.

Stupid question maybe, but *could* it be that Larrabee is based on a large number of very simple x86 cores each with a PowerVR SGX unit integrated? The individual cores could basically be the same as the ones suitable for cell phones.

SGX is highly scalable and SGX 555 is aimed / targeted at the PC space and is designed to be embedded in a SoC.
