The Best Thing That Could Happen To Intel's Pentium 4 - The SiS645 Chipset
SiS645 is clearly armed with an impressive memory bandwidth that should be able to accelerate Pentium 4 to new DDR-memory performance heights. It might even be possible that SiS645 is able to reach or even pass Intel's i850 chipset with its expensive RDRAM memory requirement. The good performance seen with SiS's 735 chipset gives us hope that SiS645 might live up to our expectations. We also tested SiS645 with DDR266 memory, since we are not quite sure about the price and availability of DDR333 right now.
We tested SiS645 in the reference platform SS51A, as seen above, which proved to run extremely stable and reliable. In fact, this motherboard didn't even crash once, neither did it show any other irregularities. It had to stand up against the fastest representatives of the i850, P4X266 and i845 chipsets, which were also tuned to maximum performance.
