Intel最新推出的9x5系列芯片组抛弃了目前主流市场上消费者能够接受而且技术成熟的DDR与AGP 8x,转而只支持DDRⅡ和PCI Express。经历过820和850两个芯片组的失败之后,DDRⅡ与DDR相比究竟有什么优势使得Intel甘于用新架构冒险呢? DDR的发展瓶颈当Intel极力推崇Rambus的时候,高昂的专利费和复杂的生产技术使得内存厂商对于Rambus没有很大的兴趣;相反,由于从SDRAM生产线过渡到DDR生产线并不需要多少额外的投入和专利费,所以DDR得到了绝大多数内存厂商的青睐。当时自信可以在市场上呼风唤雨的Intel也不得不放弃Rambus并且匆匆发布支持DDR的845E芯片组以求挽回市场份额。在当时,SDRAM由于受到系统总线
Intel’s latest 9x5 chipset abandoned the DDR and AGP 8x, which is currently accepted by the mainstream consumer market and is mature in technology, supporting only DDRII and PCI Express. After experiencing the failure of the two chipsets 820 and 850, what are the advantages of DDRⅡ compared to DDR, which makes Intel willing to risk using the new architecture? The bottleneck of DDR development When Intel strongly advocates Rambus, the high royalties and complicated Production technology has made memory vendors less interested in Rambus; on the other hand, DDR has gained the favor of most memory vendors as it does not require much extra investment and royalties to migrate from the SDRAM line to the DDR line. Intel, who was confident at the time, would have to give up on Rambus and hurriedly released a DDR-enabled 845E chipset in an effort to regain market share. At that time, SDRAM due to the system bus
