Intel's Larrabee Architecture Disclosure: A Calculated First Move

Final Words
Well, we've known it was coming for quite a while. We knew it would be a many-core CPU architecture well suited to graphics. And with as much information as we were given, when we sat down to look at what we had we felt like we still didn't know anything about Larrabee. Piles of data and information, insight into how a software render would fit on top of the underlying architecture... it has left us with the feeling that all this is a really cool idea with great potential, but we just don't have any idea what or how well it will do when it finally hits.
Of course, this is the first time any real detail has been given, and any hint of product is at least 12 to 18+ months off. We can't expect Intel to give everything away right off the bat. We are very happy to have the detail we do, and can't wait to get more.
While we are very interested in the architecture from the sort of technophile point of view that we can't help but have, technology for technology sake (no matter how cool the theory behind it might be) amounts to nothing without real-world application and benefit. For Larrabee it will all come down to peformance and price.
AMD has shown that you don't need to be on top to compete. As long as performance somewhere in the middle of the pack can be produced, appropriate and aggressive pricing can go quite a long way. For the consumer it is always a cost/benefit analysis, and there are quite a number of computers with $100 - $300 graphics cards under the hood. If compatibility is there, if performance is there, and if Intel is able to price it right, the first round of Larrabee hardware doesn't need to be ground breaking.
Getting a good foothold and sticking it out for the long haul should be Intel's goal. Compatibility (especially with the track record of Intel's integrated graphics) is likely more important than pure performance. Getting product out there into the market is necssary before developers will even start to take a chance on pushing the hardware itself. And this is where Larrabee could really shine.
Opening the door to fully programmable rendering and making it attractive enough for developers to start pushing the envelope will be a long process. The current game development arena is all about return on investment, and except for a few brave souls we will likely see game and engine developers stick to DirectX 10 for quite some time even after DX 11 comes along. Those who venture into the realm of pure software renderes written for a highly data-parallel CPU will be the exception rather than the norm.

Don't be a hater. :P Intel has got it goin' on right now. Believe in the POWAH of Larrabee... unless it proves to be a failure upon release.:)

IM FROM TEH FUTURE LARRABAE WAS CANCELLED OMG XDDDDDatlmann10 - Saturday, August 9, 2008 - link
Think about this ok AMD originally was a private IBM cpu manufacturer. Then bought out and run as a side unit of INTEL, that was dropped after they were done with them. So in a way the were partners and I'm sure there was some friendliness. As it's always been said keep your friends close but your enemies closer. There have been some things especially in these past two years that struck me kind of odd. Such as AMD's graphics chips running fine on a x38/48 chipset and the physics collaboration things as well as a few other rumors. Then Nvidia starts spouting off about how they could kick INTELS A77 etc. Now AMD has a definite GPU coprocessor in ATI and they wanna break into the market of GPU's etc. They know that there will be graphics competition with Nvidia being there largest competitior because there dedicated to GPU's solely and have a reputation. However now AMD has some chips that compete straight on weakening Nvidia to a point. Then AMD is getting more and more out of there cpu's gpu's and chipsets so INTEl jumps in the CPU GPU market just like AMD. Either way it turns out more are going to go with INTEL cpu's and many other products where AMD is kind of a fringe player. Who would you rather compete against full on 2 major GPU manufacturers or attempt to kind of co-align yourself with there competetitor while the somewhat down. Then throw out a whole new way to do graphics that performs well Nvidia is already loosing market share. So more people try it and the same number of people go with ATI. That leaves a much lower market for Nvidia plus there paying back what some 200 million dollars in bad GPU's right now as well and a few other problems they been having. Now this is not anything I know but knowing INTEL loves to stick it to competitors when there weak think about it.benkantor - Wednesday, August 6, 2008 - link
if you could fit 10 Larrabees on 143 mm^2, you could fit 40 Larrabees on 286 mm^2, not 20... :PMamiyaOtaru - Saturday, August 9, 2008 - link
For the love of education. We've already been through this. See the end of page 6 through page 7 in the comments section.143mm^2 doesn't mean 143*143. It means 143 square millimeters. 286 square millimeters is twice as many, allowing twice as many cores.

The article is right and you are so very wrong.

Derek and Anand deliver again!KGR - Wednesday, August 6, 2008 - link
I am not a profeesional about software and hardware that is why maybe this question can sound nonsense .If larrabee will have a software renderer and programmed by C++ is it possible that it is not depended on windows? I mean if it doesnt need direct X can we run the games on Linux also??

I enjoyed reading this so much. I think that this kind of articles is what Anandtech needs; I usually go to Arstechnica to read things like this one.Again, thanks!

I am definitely impressed with this new development and I expect that this technology will be disruptive down the road, however I feel that somehow they are about to commit another of their megalomaniac mistakes.Has anyone stopped for a sec and look where all gaming industry is heading into? Are PCs the future gaming platform? Maybe I am missing something but aren't the big guys already struggling to retain a 'decent' percentage of the multibillion gaming pie (PC gaming alliance anyone...)? I believe that whether us, tech enthusiast, hardcore pc gamers like it or not, it is the console arena where the big guns are going to be playing in a few years from now.
Guys, we are seeing this happening everyday, we see tittles appearing and disappearing everyday b/c companies don't want to commit the resources to develop games for more than one or two platforms (normally doing a sloppy work BTW). Now that the grandpas of graphic hardware had manage to get DX/D3D derived engines into the last gen consoles (xenos, RSX) and a terribly inertial and rigid developer community avoids and whines about how difficult is to program for the few hardware 'jewels' that we have already in our hands (Cell/RV770/G200) do you think anyone except Intel is in the mood for yet another graphics industry spin?
I have no doubt that this new development will have its own niche application or someone will definitely find something appropriate for it, but to say that Larrabee CAN do graphics and to say larrabee will kick ass so bad that in 3 years from now we all will be gaming from a Larrabee containing computer are two very different things.
Congrats to Intel as the fathers of the creature, and congrats to us to see the tech world moving on....but just don't think this will change the world as we know it.

They are doing something very AMD like and taking it a step further and tossing in a few Power ideals in. I just wonder what the power profile will look like and who will partner up with Intel for it.I am sure they will have 4+ of these cores built into integrated chip sets for OEMs and laptops to really boost those areas. And people who buy laptops will see that they can get a desktop with 'bigger larrabee' and play their games faster than their budget/laptop computer.
So it does make sense. However, it is an empire made on a lot of ifs. It will be fun to watch. Thanks anandtech for the informative article.
