Intel the Prescott strategy acceleration, throws also price edition low next year 2nd quarter
--------------------------------------------------------------------------------
- The problem to which heat is in common? The 90nm process CPU of Intel
Condition of the 90nm generation CPU of Intel is doubtful. First, the next generation desktop CPU "Prescott (press cot)" TDP (Thermal Design Power: Thermal design electric power consumption), exceeds schedule largely and clarification ("this summer, Prescott it is hot to exceed 100W. As for electric power consumption in next year head to 100W over "reference). Next, the next generation Mobile CPU "Dothan (ドタン)", from plan of 9 ends of the month - October head announcements, 2004 1st quarter slipped largely to announcement (< Kasahara > "The release of Intel and Dothan 1 quarter postponement"reference). This, as for average electric power consumption, present 0.13 μ m edition Pentium M (Banias: バニアス) it is higher. In other words, both desktop Mobile the 90nm generation has held a some problem, the possibility electric power consumption having been entwined to that is high.
On the other hand, as for Intel the yield rate of 90nm satisfactory (healthy) has set forth the strategy which shows thing one after another. For example, Prescott clock edition (2.8GHz/3GHz) it throws low 1st quarter 2004. In addition, you say that the Prescott based value (Celeron system) it throws CPU next year 2nd quarter front falling down. When it is this pace, in almost 1 year you insert the desktop CPU to 90nm from 0.13 μ m and you mean to substitute. It means that that much the prospect of the yield rate of 90nm is good.
This having shown what just? As for being for the present clear it is not found yet. But, as for 90nm of Intel, as for yield rate although it is good, leak of the transistor (a leak) it probably means that electric current is more than expectation. The circumstantial evidence which suggests that is visible there over there.
For example, as for the electric power consumption of Prescott having become more than schedule, the former way the fact that drive voltage was pulled up for high clock conversion is not cause. When actually CPU it tries being possible, because many electric currents are needed, the result, the electric power which is consumed has risen. In addition, Dothan, TDP (Thermal Design Power: Thermal design electric power consumption) average electric power consumption has risen to having gone down. It is estimated that with 90nm process holding down leak electric current becomes very much, but perhaps the problem of Prescott and Dothan, it has shown that.
Anyhow, under present conditions the strong strategy of Prescott it does not destroy Intel. Dothan which you set back up contrast, with Prescott seems like the intention of going with the policy of betting stimulation on spread.
- A little something related to complicated Prescott between FMB
As reported even before, Intel in order to solve the thermal problem of Prescott, has taken the move. The motherboard specifications "Prescott for Prescott FMB (Flexible Motherboard)" it revises. Past "Prescott FMB 1" (TDP electric current quantity Icc MAX "Prescott FMB 1.5" (103W/91A) stipulated with 89W 78A) to in addition. As for first Prescott 3.2/3.4GHz which appears within year, unless it is the motherboard which parallels to this Prescott FMB 1.5 it seems that cannot be supported as a general rule.
Intel when it enters into next year 1st quarter throws 3.6GHz, of higher clock, but unless this is FMB 1.5, you say that it cannot support. But, Intel throws also Prescott of clock edition simultaneously with that low. 0.13 μ m edition Pentium 4 (Northwood: The north wood) with it is the product of 2.8GHz/3GHz where the clock band is piled up. These support can do clock edition Prescott, low even with FMB 1 seems. In other words, as for the first half 2004 it is the possibility that FMB 1 correspondence Prescott and FMB 1.5 correspondence Prescott exist together. There is also information that small electric current edition appears even in 3.2GHz/3.4GHz, but still being able to verify it is not. In any case, with Prescott, there is a possibility the motherboard which cannot be made the motherboard which it can correspond with frequency, coming out, note becomes necessary.
That Intel, sells has Prescott in 2.8GHz and 3GHz which come to the muscle price range it has shown the fact that it has considerable self-confidence in the product yield rate with 90nm. Though, really as for this clock band also Northwood in parallel, because it is sold, whether Prescott how much quantity it comes out, still there is an unknown part. But, the plan of Intel to just a little front, was the pace that finally sells Prescott comes entering to the muscle price range at the latter half 2004. For the end user, in the sense that, they are good news Prescott directly enters into the hand at the price which is convenient.
As for good news there is one more. As for Intel with Prescott, as for the premiere of the amount which expands architecture it seems that almost it does not add in price. Presently, you start from price 600 dollars of high ended products of Pentium 4, but you say that also Prescott 3.4GHz becomes price of the class. With what is said, in the clock band which competes with Northwood under that, is presumed that also price almost reaches the same level. When with it does, as for the amount where efficiency improves Prescott architecture (1MB L2 cash/revised edition Hyper-Threading etc.) with, the possibility of becoming almost "simply" is high. And, the price of Prescott 2.8GHz which it has in the bottom means to descend directly to 2 ten thousand Yen.
The strategy of Intel which at a stroke introduces Prescott with the top two bottom. This is visible in repetition of the strategy of this year when it permeates Hyper-Threading at a stroke.
- The value edition Prescott which becomes forward fall
Intel for the value market throws also Prescott at speed of exceptional case. Usually, after CPU of new architecture & new process appearing in for the high end, it gets off to 4 about quarter it was required for the value market. However, this time as for Intel, next spring Celeron class CPU of Prescott edition is thrown already.
Concretely, 2nd quarter 2004 Prescott based value CPU, appears with 2.8GHz and 3.06GHz. Plan of the time before compared to it became substantially forward fall. Starting producing the product with 90nm process, only 2 quarter, it has to the value market whose volume is necessary, it is impact. Self-confidence to the 90nm process of Intel is rather deeply so.
Though, really from the Pentium brand, still Northwood remains even from that point in time. Depending upon the method of thinking, with the top two bottom, Northwood system and Prescott system parallel, it can also see that it has been about to offer.
By the way, Intel hastened also the discontinuation of 533MHz FSB edition Northwood. Intel to next year 2nd quarter, it was the intention of continuing 533MHz FSB Northwood, but 533MHz FSB system Pentium 4 disappears within year Prescott attendant upon clock edition throwing low. FSB of Pentium type CPU, including manufacturer make PC, moves to everything 800MHz.
However, this time it can pull up from 400MHz FSB of Celeron to 533MHz. As for FSB it becomes 533MHz from value edition Prescott, also L2 cash becomes 256KB. The difference of Prescott is of both brands sort under.
The difference of two Prescott
Pentium system Celeron system
Performance/main stream market Value market
FSB 800MHz 533MHz
L2 cash 1MB 256KB
Package MPGA478/LGA775 MPGA478/LGA775
In other words, at the point in time when value Prescott appears, Celeron system both FSB and L2 cash it is the case that it improves. In addition, value edition Prescott, LGA775 edition appears not only mPGA478. This has rather important meaning.
- The permeation of PCI Express is promoted by Prescott.
As for one of the intention where Intel throws value edition Prescott to early stage, if it is not Prescott, it is presumed that it is because of the LGA775 package which cannot be supported. Intel from 2004 2nd quarter, adds LGA775 edition to Pentium system Prescott, Pentium not only the mPGA478 edition which has 4 and compatibility. From 3.8GHz of the top to 2.8GHz of the bottom LGA775 edition parallel on all line, it is thrown. Because as for Intel hurrying the movement to LGA775, LGA775 has been related with PCI Express.
Intel new chip set "Grantsdale of PCI Express/DDR2 memory support (グランツデール)" throws 2004 2nd quarter. Only LGA775 edition CPU it supports Grantsdale chip set. Because of that, if it tries that the PC vendor will move to PCI Express, as for the choices it is gone other than LGA775 edition Prescott.
When you thought, that and, the PC vendor, would like to have PCI Express even in the value market, value edition Prescott becomes necessary.
Actually, Intel updates also the chip set road map. We had decided to throw the Grantsdale family for the value market 2004 3rd quarter. Concretely, inexpensive edition chip set "Grantsdale-GV" for the main stream market and, "Grantsdale-GL" for the value market is thrown. Only FAB 533MHz it supports Grantsdale-GL with LGA775, it is value edition Prescott private chip set.
In any case, also the permeation of PCI Express may accelerate with the Prescott strategy where Intel accelerated. Of course, such Prescott strategy depends on the completion of all 90nm process.
