Intel's Larrabee Architecture Disclosure: A Calculated First Move

The Awesome Potential of Fully Programmable Graphics
Certainly we can't judge the applicability and impact Larrabee will have until we see how it handles real-world applications. But we absolutely cannot write off such a giant as Intel when they throw their chips into the pot. Some of the current graphics hardware establishment have tried to suggest to us that Intel is not in touch with the current development community and that the only reason some developers are excited about the extensive low level programmability of Larrabee is because they are nostalgic for the old days of graphics programming where it was all about the software renderer.
I don't think anyone is under the illusion that DirectX and OpenGL performance are irrelevant for Larrabee. If Intel fails at delivering equivalent or greater price/performance in games and applications that use these programming APIs, then no matter how well the hardware could be used for any software engine it will fail. But the potential to customize every part of the rendering pipeline, the capability of supporting a software renderer with the same level of performance as if the hardware was customized to it, adds a level of value to the development community that will absolutely blow away anything NVIDIA or AMD can currently (or will for the foreseeable future) offer.
Re-opening the door for Tim Sweeney, John Carmack, Michael Abrash, and other pioneers and visionaries in the field of 3D graphics to once again have the freedom to take a piece of hardware that can offer the kind of data parallel speed that has heretofore been limited to the GPU and literally do anything they want with it is something to be excited about. Limited much less by the physical design of the hardware to once again only be limited by the performance of any given segment of code could help speed up the transition from SIGGRAPH to games. Larrabee could help create a new wellspring of research, experimentation and techniques for real-time graphics, the likes of which have not been seen since the mid-to-late 1990s.
We have absolutely been seeing the current graphics hardware giants move toward more flexibility and programmability. But if Intel is able to effectively leap-frog their slow trudge toward true general purpose programming DX version by DX version, we will see the end of an era where games are feature limited by hardware. No longer will we need new hardware to handle a new DX version with new techniques and effects: we would only need a driver update to add support for the new API. The only obstacle to running games using future APIs will be performance. The only reason to upgrade in the future will be speed. It will be a different world, altogether different than anything we've known or experienced before yet incredibly similar to the roots from which the industry was born.
It is an exciting time to be in the field of computer graphics.

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.
