Guild Companies

Intel, which has been more or less driven out of the server chipset business by the ServerWorks unit of communication chipmaker Broadcom, has been fighting to get back into that business. To that end, Intel launched the E7X00 family of chipsets with the "Prestonia" Pentium 4 Xeon DP processors in early 2002; this chipset supported a 400 MHz front side bus. The E7500 is used to make two-way servers based on the Xeon DP chip.

Such two-way machines are popular at small and mid-sized businesses as either database or application servers. In a world that consumes 4 million servers a year and about 3.7 million of them use Intel processors, selling 800,000 chipsets in a year is a big deal for Intel. Intel's figures on chipset sales mixed server and workstation chipsets, so it is unclear how many server chipsets the company is pushing out a year.

Intel also now sells an improved E7505 chipset for two-way Xeon DP servers, E7501 chipset with a 533 MHz front side bus for two-way Xeon DP servers, the E7205 chipset for uniprocessor Pentium 4 workstations, and the E8870 for four-way "Gallatin" Xeon MP servers.

This fall, Intel said in releasing its shipment statistics, the company will also debut the "Canterwood-ES" chipset for Pentium 4 servers. This chipset will support PCI-X I/O and is heavily based on the 875P chipset Intel announced in April 2003.

Next year, said Intel, it will introduce the "Lindenhurst" chipset for future Xeon DP processors for two-way workstations and servers and the "Twin Castle" chipset for future Xeon MP processors for four-way servers. These two chipsets will incorporate support for PCI Express point-to-point I/O interconnections and will also support DDR2 memory subsystems.

The Lindenhurst chipset is expected to be matched with the future "Jayhawk" Xeon DP processor in the second half of 2004, while the Twin Castle chipset will work with the future Gallatin chips with 4Mb integrated L3 cache, due in early 2004, and the "Potomac" Xeon MP chips, due in the second half of 2004.
