New Pentium 4 chipsets

Intel has so far only sold half as many Pentium 4 processors as was originally calculated. The main reason for this dilemma is that currently only motherboards with the Intel 850 chipset are on the market.

This in turn requires the cost-intensive Rambus memory modules. So far, however, these have not been able to reach the price targeted by Intel (approx. 30% above the price level of SD-RAM) and are still much more expensive. In addition, you always have to populate the memory banks in pairs. So it is primarily the high price that makes Pentium 4 systems unattractive at the moment.

Intel itself has recognized this fact and plans to launch the i845 chipset (code name: Brookdale) on the market at the beginning of July bring. This offers support for SDRAM, which will enable cheaper Pentium 4 systems than before. The trend-setting DDR memory technology has been dispensed with in the i845, and only a further version of the i845 is said to have support for DDR memory. At the Computex trade fair, however, rumors are currently making the rounds that the Brookdale 2 can only clock the memory modules synchronously with the frontside bus. Since the FSB of the Intel Pentium 4 is 100MHz, the system cannot benefit from DDR memory according to the PC2100 standard. Therefore, the cheaper and slightly less memory throughput modules based on the PC1600 standard will be used.

The through Other chipset manufacturers now want to fill this gap in the market. Ali and Via have now developed Pentium 4 chipsets that handle both SDR and DDR memory and can also fully utilize them due to a memory clock that is independent of the FSB. Via only presented the P4X266 chipset behind closed doors at Computex. According to some motherboard manufacturers, Intel Via has so far only developed, curiously enoughbut not allowed to sell the P4X266 chipset. Ali, on the other hand, does not seem to have any licensing problems with Intel and is presenting the M1671 chipset at his stand, the series production of which is to start in the third quarter. SiS has nothing to do with the hype surrounding the Pentium 4 and prefers to develop highly integrated components for the mainstream market.
