    Exclamation Intel to drop support of Rambus in new CPU products

    I read this article and thought it was worth posting

    By Jack Robertson

    Intel Corp. in the second half of this year will drop its final Direct Rambus DRAMs support in new computer products, it was learned Tuesday at the Intel Developers Forum.

    The last RDRAMs used in Xeon workstations will be replaced by new chipsets supporting double data rate (DDR memory).

    An Intel workstation roadmap secured by EBN showed a Placer chipset with DDR SDRAMs for dual processor Xeon workstations, and a Granite Bay DDR chipset for uniprocessor Xeon workstations. They will replace the Intel 860 workstationchipset using RDRAM and Intel 850 with RDRAM.

    The new Prestonia Xeon processor for servers introduced in January already uses DDR memory, supported either by Intel's own E7500 Plumas chipset or a third party vendor chipset from ServerWorks, Santa Clara, Calif. Intel's desktop and notebook lines since last year have virtually dropped RDRAM in favor of single data rate SDRAM or in January going to DDR memory as well.

    Intel will continue using Direct Rambus memory with its network processors. Also, although not new products, the next iterations of its 850 and 860 chipsets, supporting a 533MHz front-side, will support RDRAM when they arrive, probably in the second half of this year.

    But when the next generation of workstation DDR chipsets arrive, it will mark the end of a long and torturous episode when Intel tried to mandate Direct Rambus as the next generation memory for the PC and workstation markets.

    After a series of embarrassing troubles and lukewarm reception by the PC market, Intel in the last year has reversed course and shifted rapidly to support SDRAM and DDR.

    A spokeswoman for Rambus Inc. said she couldn't comment on new Intel workstation chipsets supporting DDR, and referred all questions to Intel.

    Intel roadmaps released at IDF also continued to reveal new server processors slated to be introduced in 2004. On Monday, Mike Fister, senior vice president and general manager of the Intel Enterprise Platform group, revealed the existence of a new Montecito 64-bit processor to be built on the firm's 0.09-micron processes.

    A new Intel roadmap introduced at IDF Tuesday disclosed a Nocona processor for 32-bit servers to succeed Prestonia, also built on a 0.09-micron process.

    Montecito and Nocona each reportedly may cover both the multiprocessor servers and dual processor servers with the same chip. Until now separate processor versions were needed for the two main server markets.

    E5C4P3: I just found it funny when Intel
    was sayin DDRSDRAM was inferior, but now looks like they are gonna join the DDR club.
    I think this is great, it shows to dominate the market you also have to dominate in customer
    Due to the expence and the fact Rambus is not signifiganly better than DDR.
    (remember DDR has a shorter latency time, compared to the Rambus faster retrieval.)

    Thank you -E5C4P3

    It was only a matter of time. Good find.
    Mankind have a great aversion to intellectual labor; but even supposing knowledge to be easily attainable, more people would be content to be ignorant than would take even a little trouble to acquire it.

    Didn't intel sign some contract that said they would only use rambus for a couple of years? I guess that expired...

    Does anybody else have plans to support RDRAM? If so, then who?
    Why is Intel dropping the consumer PC w/ P4 and Rambus memory? Was it too expensive? Was it because the "sticks" had to be installed in pairs?
    Welcome to Hell , where we have served more than all of the fast food chains put together! And the number grows everyday! Stay tuned!

    well basicly they wanted to make so if u wanted a p/4 processor u had to buy an Intel
    motherboard and Rambus memory.
    the draw back you could purchase an AMD processor which was .2 G htz less than the P/4 and, and and a motherboard and you would still have some money left over, compared to just buying a P/4 processor.
    I guess people figured what if i need to upgrade my memoy?
    Im I gonna spend an arm and a leg on Rambus memory?
    Rambus is considerably more expensive than DDR.
    I guess people were more financially savey than Intel suspected.
    Also you didnt have to install rambus in pairs u do with ddr though
    but u did need to place "connectivity cards"
    (sorry the proper term eludes me right now) in the empty rambus slots
    to complete the circut.
