kohlrak: larrabee wouldn't be an x86 killer, as the individual cores are kinda "dumbed down" compared to the current core2 arch... the great force of larrabee is that it's highly parallel, which is something we can't currently take much advantage of for "regular apps" - a quadcore core2 will handle your daily needs better than a 48-core larrabee Smile

Eh, usually whenever someone pushes a project back, they're trying to slowly let some PR die down, because they don't think (or don't want to) meet a particular goal. My guess is that they did something right for once and are afraid that if they sell it, they won't be able to beat it. I could be wrong, but why else would they hold this from us if it's as so far along as it supposedly is?
Why not just release a stripped down version then? Or charge an insane amount? They've never been shy of doing the latter for their new products before..


Because if they felt they could NEVER beat it, when the price eventually comes down, they're up the crick without a paddle. It's like politicians. If they actually solved the problems, they'd be out of a job. If this CPU design and theory actually does what it promises, it would send x86 CPUs down a path of great improvement with little room for more. If other CPU archs used the idea and it worked, it would put intel out of business since it's cheap and many archs could out perform x86 if they put as much development cost into the product as you're regular x86 gets.
They better do it before someone else does, then.

Indeed. It's also possible that this is just to make intel LOOK good, so people buy intel products with the assumption that intel's got it right at heart, just came short of accomplishing something. If this project failed, it still may look good for intel, and people might think other intel processors got some great "secrets" in them.

To be honest, when it comes to intel trying to improve, it'll be hard to convince me that it isn't really an improvement, but just some sneaky trick to knock out the competitors. It's not unlike intel to pull that crap.

If it is something that could potentially break x86, they're probably hoping that if they shut it up for now, no one will figure it out until they've had enough time to fix everything they broke/didn't do right with x86 (Branch prediction, all those ugly standards like various A20 things, having to scan for certain structures, this, that, and more, etc).

From IT PRO news:
Quote:
Intel has announced that its Larrabee graphics project will be shelved, at least in its original form, due to performance lagging behind the competition.

In a statement made to CNET.com Intel spokesman Nick Knuffer said, "Larrabee silicon and software development are behind where we hoped to be at this point in the project. As a result, our first Larrabee product will not be launched as a standalone discrete graphics product."

Larrabee will appear instead as a software development platform, which implies that work will continue on the project in some form.


Looks like the larrabee chip is only going to be used in server/workstation markets only, for the near future. Too bad, I would've liked to see something like this on the market.

Actually I read a lot of articles on the subject and I got the next impression:
1) Larrabee will not be sold to us (mortals), as said before by one poster
2) Larrabee will not be sold to power HPC/GPGPU servers
3) Larrabee will only be a testing/dev. trampoline

* 3rd one means that they will only make a 1000 of them or so.

and finally:
4) 48-core "thingy" isn't Larrabee, but a very different thing. I don't know what should it be called, but THAT is the one with 25..125W

Larrabee itself will use ~300W (because its high-performance) Razz
