IBM aims for Summit with dual 32-bit, 64-bit chipset

Big Blue hopes to mount McKinley

Intel has selected chipset technology from IBM to test upcoming multi-processor versions of its Xeon server chip and the next-generation Itanium processor, McKinley.

IBM's Summit is the first chipset that can be used with both 32-bit and 64-bit processors, and it hopes that Intel's validation work will allow it to be one of the first to market with xSeries servers based on multi-processor versions of Xeon.

Each Summit chipset joins as many as four Intel Xeon MP processors together - enabling them to share resources such as I/O and memory - resulting in up to a 20 per cent increase in overall system performance. The chipset features IBM-developed technologies, such as copper interconnects and silicon-on-insulator fabrication.

Summit will also incorporate a PCI-X add-in interface, effectively designed to double data transfer rates. ®
