Pentium chips will be on severe allocation throughout 1993 with no one company getting more than 5,000 or 10,000 units total, according to what Intel Corp is telling its customers, our sister paper Unigram.X reports, adding that these kinds of quantities will go only to Intel’s best customers. Others will have to make do with deliveries in the tens or hundreds depending on who they are. The allocation policy is apparently the result of production difficulties. Sources however think that what will be delivered after the chip is finally announced, probably at the tail end of this quarter, will be the promised 66MHz units. Intel has had difficulty getting working parts over 40MHz and even at that reduced speed the silicon produced so much heat it required a heat sink and a fan. According to the current timetable, if development of Pentium’s P6 successor chip stays on course, it could step on Pentium’s toes. Intel is therefore said to be telling customers that the P6 will be deliberately held back from the market, despite its state of readiness, to enable them to recoup their investment in Pentium. Last quarter Intel was openly talking about introducing the P6 at the end of 1993. Thanks to Intel’s vigilance, P6 specs are hard to come by. We hear that they may be try-ing for 2.5V operation to reduce the heat dissipation. Meantime US PC Week reports that the first machines to use the Pentium won’t be able to exploit the full potential of the processor. As well as the heat dissipation, the machines will be slowed by the very complex design and by slower support chips.
