Even Ottelini confirms Intel got back to us after our original story that Larrabee got delayed to 2010 telling us that the chip was not delayed and that the plan was to launch it in 2009/2010 timeframe. According to this statement Intel claims Larrabee is still on schedule. Intel´s representatives came back to us claiming that Larrabe in 2010 is not something new and that even Ottelini Intel´s CEO confirmed 1H 2010 as the target for Larrabee launch in Intel´s last conference call. If they don´t delay if further, Larrabee will have to fight the one we call R800 and the one we call GT300, if not even their offspring.

Bill Dally nell'intervista dice che non è preoccupato per quello che sta facendo Intel con Larrabee.
Hardware Upgrade - Cosa ne pensa di Larrabee, ne teme, in qualche modo, l'arrivo sul mercato? Risposta - Intel è sicuramente una compagnia da temere e che sa come lavorare e quando una azienda di questo tipo guarda e mira al tuo mercato principale, c'è da preoccuparsi. Dopo aver visto i primi dati e le prime informazioni, che anche voi dovreste conoscere, non mi posso dire preoccupato. Ci sono gravi mancanze nella loro pipeline grafica, che rendono il prodotto lento, soprattutto per il target cui intendono commerciallizzare la soluzione. Dai primi dettagli posso desumere anche che si tratterà di una soluzione dalle prestazioni modeste, ma che richiederà parecchia energia per funzionare. Sarà inoltre dotato solo di 4 threads per core, e questo rappresenta un limite soprattutto nella gestione della memoria. Imho però dal lato GPGPU alla nVidia si stanno un po' cagando addosso. ![]()

Intel Corp. will start educating software developers to use its code-named Larrabee graphics processing units (GPU) efficiently and utilize their unique capabilities at Siggraph conference due in early August ’09. This is virtually the first time when Intel plans to publicly reveal ways of advanced utilization of Larrabee among more or less wide audience. During the presentation entitled” Preparing for Larrabee”, Intel will discuss Larrabee architecture as well as ways to program the Larrabee graphics processors. Thanks to compatibility with x86 instruction set as well as Larrabee new instructions (LNI), Intel’s first graphics processors in more than a decade enables a greater degree of programmability than previous GPUs. However, the opportunity to innovate presents a challenge: how can developers leverage their existing codebase and assets on this platform whilst opening up avenues to exploit the hardware? During the presentation, the representatives for Intel will present some of the approaches available, along with insights into how developers can get ready to leverage them. Three fundamental approaches are covered: optimizing graphics API usage for the hardware’s unique features, sharing data between Direct3D and a Larrabee native application and writing pure Larrabee native applications. In another presentation called “SIMD Programming with Larrabee” Intel plans to present some of the key features of LNI with particular emphasis on their utility in graphics applications. The material is aimed at developers already familiar, but not necessarily expert, with SIMD programming and C++. This is practically the first time when Intel intends to go in-depth regarding Larrabee peculiarities in public. Considering the fact that the world’s largest chipmaker plans to initiate shipments of Larrabee in the first half of 2010, it is pretty late to start educating developers regarding its unique capabilities. In practice, this will mean that a significant number of game developers will hardly utilize Larrabee’s advanced features inline with its actual launch. Siggraph conference will be held from the 3rd to the 7th August, 2009, whereas the Siggraph exhibition are scheduled for 4 – 6 August, 2009. Both events will be held in Ernest N. Morial Convention Center in New Orleans, Louisiana.

ONE OF THE best open secrets in the industry is about Larrabee and it's eventual integration into Intel's core Core CPU line. It is going to happen, just a bit later than many expect. The integration is set for the Haswell generation, just over three years from now. For those not up on the current Intel long term roadies, the current core is called Nehalem and it is followed by a 32nm shrink named Westmere due late this year. In late 2010, we have another core called Sandy Bridge. It is followed up by Ivy Bridge, a shrink to 22nm in late 2011. Late the following year, 2012, wewill see the debut of a core called Haswell. Even if some Intel execs dare not utter it's name, it was officially disclosed in slides at the Spring 2008 IDF in Shanghai. You can see the slide in question on CarardPC here. The specs of the chip itself are still a little fuzzy, but given it is three years out, that is to be expected. The one thing we can say for sure is that it will have Larrabee compatible graphics on die. The current chipsets, soon to be CPUs, have GenX graphics. No, not the Billy Idol band, but the architecture that took the bottom of the market by storm with the 965G, and continued to set new lows with the G35 and G45,and it will soldier on for another 3 years before it is finally put down. Although the GenX architecture is strongly rumored to have finally been done right in the G55 generation, it is running out of steam. Larrabee needs to have the surrounding software infrastructure built up, both drivers and compatible programs that hit the metal directly, before Haswell debuts. Given how much work it takes to get a solid and capable driver set out, the Larrabee team has a lot of work ahead of them. It is going to be very interesting to see not only how well, but also how soon all this software gets fleshed out.S|A

http://www.semiaccurate.com/2009/09/...out-weeks-ago/
New Larrabee silicon taped out weeks ago Plagues of bugs quashed IT LOOKS LIKE Larrabee, Intel's upcoming GPU++, is about to have new silicon in short order. The B0 stepping taped out about a month ago, so there should be some public showings soon. B0 taped out on August 15, and the silicon is winding it's way through the fabs now. Even with Intel's manufacturing prowess, making those parts and bringing up the new silicon takes time. It is going to be a really close call on them making showable boards before IDF or not. Here's to hoping. Word on the street is that Larrabee has a host of bugs which prevented public showings of the Ax silicon. This is not uncommon for a new architecture, and a new paradigm only adds to the pain. That said, almost all problems are said to be fixed in the move from Ax to B0 silicon. If schedules don't allow for the new stepping to be shown at IDF next week, expect a flood of demos at the next major conference. From the looks of things, Larrabee is going to be pulled from a shroud of mystery and negative rumor into the light very soon. Only then will we see if it lives up to the hype or not. Game on in a matter of weeks.S|A

Si parla di Larrabee
As for Larrabee, Intel's Sean Maloney showed a real-time ray-tracing demo that seemed to run at somewhere around 25 FPS or less. The demo was interesting graphically the way that, say, solo bassist Stanley Clark is interesting musically—you're mightily impressed by the sight of something so difficult being done with such speed, but the end result isn't really the kind of thing you want to rock out to on a regular basis. The real-time ray tracing stuff just doesn't look that great yet, and it probably won't look as good as rasterized graphics anytime soon. ma è interessante anche per il resto http://arstechnica.com/hardware/news...akes-a-bow.ars

Ho come la sensazione che stavolta Intel paghera' la sua "arroganza" evidentemente la mancanza di know how ha pesato...e non poco...tutto quello che si è visto è stato a dir poco deludente e il continuo rinvio di notizie non fa presagire nulla di buono...mah

Beh ragazzi, auguratevi che Larrabee funzioni e abbia prestazioni competitive perche' altrimenti mi sa che Intel si compra Nvidia e cosi' taglia la testa al toro.

Mi sembra anche normale: il raytracing in realtime richiede un'immensità di risorse, e non penso fosse lecito credere che il raytracing avrebbe preso il posto
Quote:
Da un certo punto di vista è da premiare la spinta di Intel verso un'innovazione, il mondo delle schede grafiche in fondo sta arrivando ad un'impasse... Con la rasterizzazione ad un certo punto si arriverà ad un limite dettato dall'impossibilità di cambiare processo produttivo con facilità. Come sappiamo, le aree fixed function sono molto più grandi di quelle programmabili, quindi già in un chip come RV870 ci entrerebbero probabilmente con facilità il doppio o anche più di SP, eliminando TMU e ROPs. Ovvero già oggi potremmo avere sistemi da oltre 5 TFlops... Il problema è che occorrerebbe cambiare radicalmente il modo in cui si crea l'aspetto puramente grafico di un vg... Potrebbe essere uno scenario interessante, ma credo che se non l'hanno già fatto ci sia un motivo... Intel avrebbe una fetta troppo grande del mercato delle schede grafiche (includendo le integrate), dunque l'acquisizione con tutta probabilità verrebbe bloccata dall'antitrust competente...

A giudicare da quello che si legge Larrabee rischia di essere una delusione colossale, anche perchè non si sa quando uscirà e nel frattempo Amd e Nvidia, ovviamente, tirano fuori prodotti sempre più potenti

Vedo che le aspettative sono molto alte con Larrabee ![]() http://www.digitimes.com/news/a20091103PD203.html Intel CEO promotes Larrabee privately during China visit Intel CEO Paul Otellini has privately talked to several China-based graphics card makers to promote its Larrabee GPU, which is set to launch in 2010, during a recent visit, according to sources at graphics card makers. The sources revealed that Intel plans to offer preferential pricing for the GPU purchased by itself, and bundled with other Intel products to attract partners. Although several first-tier graphics card makers remain conservative about adopting the GPU initially due to fears the chip may still have bugs; however, they expect Larrabee to have a chance of competing against AMD and Nvidia after two years.
