Краткое содержание статьи: Everybody knows it, Pentium III plus an i820-platform with RDRAM is an expensive combination. Therefore many i820-motherboards and systems are sold with Intel's 'MTH' chip and SDRAM instead, without making the customer aware of the horrible performance penalty of this combination. We found out that today the best Pentium III (Coppermine)-platform comes from VIA. The Apollo Pro 133A chipset offers a performance that's close and in some cases even equal to i820 with RDRAM, but at a much more reasonable price point.
Performance Showdown at 133 MHz FSB - The best Platform for Coppermine
Intel's new chipset, that was supposed to support the 'Coppermine'-processor, was first known under the code name 'Camino'. It was supposed to be the first PC-chipset to support Rambus or RDRAM. RDRAM was and still is not exactly popular in the industry, because Rambus Inc. owns the design and so each memory maker producing RDRAM has to pay royalties to Rambus Inc. Intel didn't bother about that, since history had proven that whatever Intel proclaimed as the future direction was finally accepted by the world. Unfortunately however, the Force had left the designers of Camino. The effect was rather devastating. 'Camino', today known as 'Intel 820' chipset, turned out to have a major bug in the very last minute before its planned release. This had been relayed to the poor motherboard makers so late, that some of them couldn't even stop their marketing campaigns for i820 anymore. Intel also decided against any further delay of 'Coppermine', so that this new processor was released without an Intel-platform for it. What happened after that is history and known to all of us. Finally i820 was released, but castrated to only 2 RIMM slots for the super expensive RDRAM. The Intel820 chipset may perform well, but nobody can afford RDRAM. Thus people considered Intel's half-baked 'MTH'-solution that supports PC100 SDRAM. It translates the parallel CPU protocol in the serial RDRAM protocol and then back into the parallel SDRAM protocol, which results in mediocre performance. The next thing that came as a shock was when Intel admitted that i820 plus SDRAM is having problems as well. ECC SDRAM leads to crashes, which is as paradox as it comes, but who would wonder about that anymore? We've learned to expect the craziest stuff from Intel today.
