Things That Could Go Wrong

I had to write this section because as strong as Intel has been executing these past couple of years, we must keep in mind that in the GPU market, Intel isn't only the underdog, it's going up against the undefeated. NVIDIA, the company that walked into 3dfx's house and walked away with its IP, the company who could be out engineered and outperformed by ATI for an entire year and still emerge as dominant. This is Intel's competition, the most Intel-like of all of the manufacturers in the business, and a highly efficient one at that.

Intel may benefit from the use of its advanced manufacturing fabs in making Larrabee, but it is also burdened by them. NVIDIA has been building GPUs, some quite large, without ever investing a dime in building its own manufacturing facility. There's much that could go wrong with Larrabee, the short list follows:

Manufacturing, Design and Yield

Before we get to any of the GPU-specific concerns about Larrabee, there's always the basics when making any chip. There's always the chance that it could be flawed, it might not reach the right clock speeds, deliver the right performance and perhaps not yield well enough. Larrabee has a good chance of being Intel's largest die produced in desktop-like volumes, while Intel is good at manufacturing we can't rule these out as concerns.

Performance

As interesting as Larrabee sounds, it's not going to arrive for another year at least. NVIDIA should have even higher performing parts out by then, making GT200 look feebile by comparison. If Intel can't deliver a real advantage over the best from NVIDIA and AMD, Larrabee won't get very far as little more than a neat architecture.

Drivers and Developer Relations

Intel's driver team now is hardly its strongpoint. On the integrated graphics side we continue to have tons of issues, even as we're testing the new G45 platform we're still bumping into many driver related issues and are hearing, even from within Intel, that the IGP driver team leaves much to be desired. Remember that NVIDIA as a company is made up of mostly software engineers - drivers are paramount to making a GPU successful, and Intel hasn't proved itself.

I asked Intel who was working on the Larrabee drivers, thankfully the current driver team is hard at work on the current IGP platforms and not on Larrabee. Intel has a number of its own software engineers working on Larrabee's drivers, as well as a large team that came over from 3DLabs. It's too early to say whether or not this is a good thing, nor do we have any idea of what Intel's capabilities are from a regression testing standpoint, but architecture or not, drivers can easily decide the winner in the GPU race.

Developer relations are also very important. Remember the NVIDIA/Assassin's Creed/DirectX 10.1 fiasco? NVIDIA's co-marketing campaign with nearly all of the top developers is an incredibly strong force. While Intel has the clout to be able to talk to game developers, we're bound to see the clash of two impossibly strong forces here.

היצור של אינטל זה הנקודה הכי חזקה שלה..... (שאר הדברים נכונים)

היא כרגע בדור שלם לפני שאר העולם וזה ככה כבר המון מאוד זמן

גם ה45nm של שאר המתחרות (שעוד לא יצא) הוא ללא high-k metal מה שמהווה בעיה להפתחות עתידית

[Screw_Master]

High-K metal gate יש גם ל-IBM, לא?

[RTTW]

לא, כרגע ל-IBM אין HIGH K METAL לתהליך ייצור של 45NM אבל הבנתי שיש להם את זה לתהליך ייצור 32NM ....

[TheReaper]

הם לא הגיעו כבר ל22NM?

[RTTW]

גם וגם

[alexbmw]

כן והם אומרים שהם רוצים שזה יהיה השלב הבא של AMD אחרי ה 45 nm בכך הם יעקפו את אינטל .

[RTTW]

אבל שוב ה-45NM שלהם הוא ללא HIGHKMETAL וגם כנראה ה-35NM או משהו כזה גם ללא רק 22NM הבנתי שהוא אכן סוף סוף אם הטכנולוגיה הזאת...

[alexbmw]

תיקרא פיסקה אחרונה

יהיה high k ל 32 nm

[djelectric]

זהו בכל מקרה הנהלם הראשונים יהיו 45NM

ורק אחרי כמה חודשים ייצאו ה32NM

[dmanbuhnik]

שימו לב שיש הבדל בין "יש להם" ל"יש להם ביצור" ההפרש הוא כמה וכמה חודשים טובים (אם זה טכנלוגיה בשלה)

וגם, אנחנו מדברים פה על יצור צ'יפים גדולים ולא תאי זכרון ששם נתין להחיל תהליך יצור חדש יותר בצורה מהירה יותר

[alexbmw]

הם כבר יצרו 300 nm Wafer של ה 22 nm זה אומר שבעיקרון יש להם יכולת יצור פשוט היא עדיין לא בשלה כי צריך להיתגבר על בגים למיניהם.

First Larrabee to have 48 cores, 80 Core version comes later

[alex.turovsky]

1. שמח שיש זקיפים שעומדים על המשמר יחד איתי

2. אני כבר מחכה לתצוגת תכלית של ה SAMPLES שהיצרניות יקבלו עוד כמה חודשים בסוף השנה.

לדעתי LARRABEE+NEHALEM+P55 יהיה הלהיט של סוף 2009 או תחילת 2010
