Chuck, re: <My understanding of AMD roadmap is PC100->PC133->DDR->DR. So, I think AMD is well set on the platform side. My only beef is these things should be happening faster than the rate at which they are happening now.> I agree with you, but I blame it on AMD's limited resources and other pertinent issues they had to deal with to have the Athlon platform viable. It will be interesting to see who (AMD or Intel) is going to come out first with DDR SDRAM support. Here is an article from EBnews, about DDR & RAMBUS: ebnews.com _______________ Benchmark battle brews between DDR, Rambus The opening salvo has been fired in the performance battle between double-data-rate PC266 SDRAM and Direct Rambus DRAM. Bert McComas, analyst with InQuest Market Research, Gilbert, Ariz., issued a report today claiming that in benchmark tests DDR SDRAM had a 10% to 30% performance advantage over Direct Rambus when compared using evaluation programs from Intel Corp. McComas' report comes just days before Intel is slated to roll out its Camino PC core-logic chipset and Direct Rambus memory platform, which have been delayed twice since their original March launch date. And the findings are sure to be quickly dismissed by memory architect Rambus Inc., Mountain View, Calif., which at next week's fall Comdex show in Las Vegas is expected to present its own benchmark tests supporting the performance of its Direct RDRAM packet-data memory interface. The InQuest test used a Vancouver motherboard and Camino chipset supplied by Intel and two double-sided 256-Mbyte 800-MHz Direct RDRAM RIMM memory modules from Samsung Electronics Co. Ltd. The platforms was tested against a Samurai DDR chipset from Micron Technology Inc. supporting Micron's 64-Mbit PC266 SDRAM in buffered PC2100 DIMMs. Both tests used Intel's new Coppermine Pentium 733-MHz processor, and each system was tested using the University of Virginia standard StreamD benchmark, according to McComas. The Samurai/DDR combo beat the Camino/Rambus duo with an average performance advantage of 24.4% in a series of tests, and exceeded 30% in some cases. Tests using the WSTREAM.EXE benchmark showed DDR besting Direct Rambus by a much smaller average of 2.7 %. McComas said he also ran both systems under the Intel Platform Test program to evaluate bandwidth between the Accelerated Graphics Port (AGP) and DRAM. McComas said the Samurai/DDR PC266 platform outperformed the Camino chipset with 256 Mbytes of Rambus memory by 13%, and by 20% when 512 Mbytes of RDRAM were used. Yet another Intel Platform Test showed DDR PC266 had a 58% performance advantage over the 200-MHz DDR SDRAM used by Intel in earlier tests, whose results were disclosed at the fall Intel Developers Forum. ebnews.com _______________ Regards, Goutama
