EETimes heeft een behoorlijk dik artikel gepost over het Intel Rambus vs PC133 geklooi. Vorige week werd bekend dat Intel PC133 (zoals verwacht) in heroverweging ging nemen, dit ivm de problemen bij de produktie van het zogenaamd superieure Rambus DRAM (eerder toonde Tom aan dat PC133 op dit moment sneller is dan Rambus DRAM). Hier heb je een hap uit het artikel van EETimes. Zie ook de belachelijk hoge Rambus prijzen:
PC133 does have a large cost advantage over RDRAM, however. "We now offer a PC133 128-Mbyte DIMM at $143 per unit," said Robin Chang, associate director of product marketing for Acer Technology Inc. "In comparison, our 144-Mbyte RIMM module costs about $840."
But, with consumers receptive to the appeal of faster-megahertz memories, and cost considerations ever more important, sources said Intel almost surely will take its chip sets to the PC133 speed. The sheer cost difference between the SDRAM and Rambus solutions continues to plague Intel's decision, made in December 1996, to support the Rambus technology.
MacWilliams said the recent sharp decline in the price of the PC100 SDRAMs — albeit with a small bounceback over the past 10 days — has widened the price gap between the SDRAMs and Rambus DRAMs. "The DRAM vendors are losing lots of money on SDRAMs," MacWilliams said. "As prices go down they are less willing to track the same aggressive pricing with RDRAMs."
While the additional cost of making an RDRAM is estimated by Intel to be from 20 percent to 30 percent higher than SDRAM at most DRAM vendors (one vendor said its cost adder was 50 percent), the prices charged for RDRAMs in the early days of the marketplace are four to five times as much as for SDRAMs. And while DRAM vendors try to charge as much as possible for RDRAMs, the collapse in the SDRAM price has made the difference between the two memory types particularly glaring, MacWilliams said.
DRAM vendors are charging a stiff premium for RDRAMs running at 400 MHz, which delivers 800 Mbits per second by reading data from both the rising and falling edge of the clock. Estimates for the price of a 128-Mbyte RIMM vary considerably. Intel said such a module would cost about $200. A DIMM of similar density, populated with 64-Mbit PC100 SDRAMs, would cost about $80.
One small module maker in Taiwan said its 128-Mbyte RIMM sells for $840; Intel officials dismissed that price as an aberration. Hyundai Electronics America said it is currently selling 128-Mbyte RIMMs "in the high $300-to-$400 range," said Farhad Tabrizi, the company's strategic memory marketing manager.
The price of the 128-Mbyte RIMM should drop to $250 by the fourth quarter, at which time the 128-Mbyte PC133 DIMM will sell for about $100 to $125, Tabrizi said. The 100 percent premium will reflect the higher cost of the RDRAM package, the more expensive testers, and the larger die size of the RDRAMs, he said.
