7/9/2001: Pentium 4: new models and bad yield with SDRAM
As it was waited and we announce already on these pages, last week Intel he announced the throwing of two new models of Pentium 4, to 1,6 GHz and 1,8 GHz. Apart from the speed, the characteristics of these mikes have not changed by no means, being still models made of 0,18 microns and of format of 423 pines.
Almost at the same time, there have been known the first tests of yield independent from the chipset Intel 845 Brookdale, from the hand of the well-known web site Tom's Hardware. This chipset is characterized for being the first one with support of memory SDRAM (PC133) for Pentium 4, what should low the price of the price of these systems, seriously penalized by the memory RDRAM of Rambus.
... Nevertheless, the tests demonstrate awful yield of the Pentium 4 with SDRAM: up to 25 % slower than with RDRAM, who is said soon. It seems that to the Intel mike there is not enough to him the band of 1 GB/s of the PC133, which does not wonder thinking that the use of a double channel of RDRAM offers him 3 times more...: nevertheless often the Athlon overcomes him with facility!
Why have not they decided for using memory DDR-SDRAM? His secret average agreement with Rambus? Does conviction of which the consumer has not even idea of what demons buy? Mysteries of logical "Made in Intel"...
On the other hand, Intel has extended his average-low scale of microprocessors, with a model of Celeron of dessert to 900 MHz and a Celeron for portable to 850 MHz. The first one, despite there is slower enough than the AMD Duron, insurance that it will be in many PCs; the second one, more advisable, at least will lower the price of the portable ones. One of lime and other one of sand?
