As processor technology has crossed the 1 GHz boundary, the bottleneck in system design has frequently shifted to how fast data can be transferred between chips. Direct Rambus DRAM (RDRAM) technology offers higher memory bus throughput speeds to address the needs for bandwidth. Here are some things you may or may not know about Intel and Rambus technology. Myth: RDRAM is expensive and will always be more expensive than SDRAM or DDR. Reality: RDRAM prices are falling rapidly. From Q2 ’00 to Q2 ’01, the price for a 128 MB RIMM (non-ECC) has come down over 65%. Samsung, the world’s leading supplier of RDRAM, projects only a $20 difference between 128 MB of PC133 SDRAM and PC800 RDRAM by the end of 2001 for large OEM volume. Prices will continue to fall in 2002. “We think RDRAM will be very price-competitive with DDR memory. If the volumes are high enough, then it may be the same price, and if RDRAM volumes are significantly higher, then it could be even cheaper.” – Geoff Hughes, Samsung senior vice president of sales and marketing as quoted in EETimes, 3/29/2001 Myth: RDRAM has no real performance benefits. Reality: Dual-channel RDRAM provides 3.2 GB/second of memory bandwidth to the system. Combined with the Intel ® Pentium ® 4 processor’s 300% increase in system bus bandwidth compared to the Intel ® Pentium ® III processor, today’s RDRAM platforms provide noticeable performance benefits. On applications that are not bandwidth con-strained, such as word processing, RDRAM may not differ in performance compared to other memory technologies. However, on intense applications that tax system bandwidth, such as XML-based Internet tools, media encoding/decoding, streaming technologies and 3D graphics, the Pentium 4 processor with RDRAM provides a superior user experience. Myth: Memory vendors are not building RDRAM. Reality: Memory vendors are most definitely building RDRAM, and they are ramping production at tremendous rates. “Samsung Semiconductor Inc., San Jose, Calif., Monday said it has exceeded $1 billion in revenue to date from its Direct Rambus DRAM (RDRAM) shipments. The Korean chipmaker reiterated that it is expanding RDRAM production to achieve 10 million units a month during this half and 20 million units a month during the second half of the year. The company also repeated its previous announcement that a new, less costly, four-memory bank RDRAM chip will enter production in the second half. The new chip is expected to be 20% cheaper to make than the current 32-bank RDRAM.” – EBN, 3/19/2001 “Japanese chip and PC maker Toshiba Corp said on Friday it will more than triple its output of Rambus DRAM chips by September while cutting commodity DRAM production, and NEC Corp said it is eyeing a similar move. A Toshiba spokesman said the company would boost its output of Direct Rambus DRAMs, which use technology from Rambus Inc that speeds up memory chip performance, to eight million units per month by September from the current 2.3 million units, based on a 128 MB equivalent.” – Yahoo Finance, 2/9/2001
