Big Blue unveils chip plans

IBM has announced its forthcoming 64-bit microprocessor as well as details of a future chip architecture for its midrange servers, writes Antony Adshead.

The S/390 64-bit microprocessor, codenamed Blue Flame, will be used in the zSeries 900 mainframe and will support 21-, 32- and 64-bit applications concurrently. The future architecture of the Power4 processor was also announced at the Microprocessor Forum last week in California.

Analysts see IBM's plans as an attempt to outgun Sun Microsystems.
