Larrabee die shot tips up

Larrabee die shot tips up

A photo of what appears to be Larrabee's die has tipped up in a presentation at the opening of Intel's Visual Computing Institute at Saarland University, Germany. Image Courtesy of PC Games Hardware.

The eagle eyed folks at PC Games Hardware have managed to snag what looks to be the first die shot of Intel's upcoming Larrabee many core processor at the opening of the Intel Visual Computing Institute at Saarland University, Germany.

Justin Rattner, Intel's Chief Technology Officer, gave a talk at the event where he talked about how much computing power was required for Visual Computing.

Rattner said that its Nehalem and Larrabee processors were possible solutions to the 'problem'.

Analysing the high res version of the photo, there look to be at least 32 cores, 32 vector processing units and possibly eight texture quadrants – there are another four, smaller structure on the die that are unaccounted for and Intel doesn't want to release more detailed information.

PC Perspective received a statement from Intel that said, "Larrabee is healthy and in our labs right now. There will be multiple versions of Larrabee over time. We are not releasing additional details at this time."

This might mean there are differing numbers of cores on the first Larrabee-based products. Thus far, rumours suggest that Intel is expecting to launch Larrabee either in the fourth quarter of this year or the first quarter of 2010 with somewhere between 32 and 64 cores – we expect it will be manufactured using Intel's 45nm High-K metal gate process technology.

yawn... wake me up when something interesting and fast comes along like Nvidia GT300 or AMD/ATI RV870

I don't know... Larrabee has some interesting potential. It really just depends what it's performance/watt is going to be like. Probably terrible, but we'll have to wait and see.

Intel's hype machine seems to be kicking into overdrive... But they'd better show Larrabee actually working...

As for the claims of superior technology... You know, history is full of failed products that were far superior to their competitors, but never could amass enough support and ended up discontinued.

The whole PC industry is locked on the path of CPU + GPU configuration (this is called, non-surprisingly, path-dependency...). Changing paths is enormously expensive, and either Intel is seeing something we are all missing (and they will be granted a renewed monopoly of the pc platform), or they are headed straight to the wall.

I believe in Larry. It won't win the performance crown but it might as well be a competitor for both nVidia and ATi. If not in the high-end market, maybe in the mid-market segment or for professionals if Intel's claims are at least somehow based on reality.

what? no cache on this die?

Or have they counted cachefields as cores?

From what I've read Intel know they are not going to win the performance crown...at least with the first iteration of larrabee....but in the mid range market to have a graphics card which can also accelerate many everyday tasks is an obvious win solution. Once it secures a good foothold in the mid range market then software/game developers will start to program towards it particular strengths, perhaps raytracing and from there it will go on to take the high end market also....I guess what I'm saying is that it's not going to be a flash bang event but more of a several year process which intel will win in the end.

mhm... each process its own core... and 20 cores over to game on... me like. hope win7 is up to the task.

If you look at what John Carmack has said in recent years and continues to say, Raytracing is not the way forward for modern game software. Even if there were things capable of running it, it'd be so stupidly expensive in terms of performance vs. gains, that there's no real point to it. Look up his speech on idTech 6.

Who knows perhaps we will end up with a hybrid of both......the extremes of any argument never seem to be the final solution....I'm just hoping that all the new stuff that is floating around at the moment ( larrabee, gpgpu, lucidlogix hydra engine and the caustic raytracing system) actually gell together to provide a real boost to what is possible....interesting times indeed.
