Pentium4 chipset from SiS with DDR400 support?
After SiS presented their SiS645 chipset with support for DDR333 RAM for the Pentium4 at the end of August, a new chipset has now appeared on the roadmap. One of its main features should be the support of 400MHz DDR-RAM and it is planned to bring it to the market in 2002.
Although there is not even memory available for its direct predecessor, the SiS645 mentioned above, which is capable of exhausting the chipset, SiS wants to go one step further and thus continue to be at the forefront of DDR SDRAM for the Pentium4 claim before the competition even caught up. The success of the SiS645 already seems certain, as it has a time advantage over the two competitors from Intel and ALi. Compared to the P4X266 from VIA, it can play another trump card, which is particularly important for the mainboard manufacturers: SiS has Intel's permission to develop chipsets for the Pentium4. VIA, on the other hand, is involved in a legal dispute with Intel, as they claim to have such a license, but Intel denies this.
