Intel to retire Rambus chipsets

X-bit Labs reports that Intel is discontinuing the production of its 850E and 860 chipsets. This move should come as no surprise following the launch of the dual-DDR400 875 chipset, which supports the faster 800MHz front-side bus of newer Pentium 4 chips.

Intel's move will leave SiS as the only producer of PC core logic supporting RDRAM. SiS' dual-channel R658 chipset has not proven popular among motherboard manufacturers, ABIT being the only taker.

This may not be the end of Rambus on the desktop, however. In the third quarter of this year, the SiS R659 is slated for release. The new design will provide quad-channel RDRAM running at 1200MHz for an amazing 9.6 GB/s of memory bandwidth, compared to the i875's 6.4 GB/s. Perhaps even more importantly, R659 has the backing of ASUS.
