IBM introduced a Unix-based server, build around a new, 0.13-micron version of its 64-bit microprocessor line.
The new eServer p650 server marks the debut of IBM's next-generation processor for servers, dubbed the Power4+.
Initially operating at speeds of 1.2- and 1.45-GHz, the Power4+ processors are 184-million transistor devices that feature 1.5-MB of L2 cache and 32-MB of L3 cache on a 267-square-milimeter die. Power consumption is said to be 70 Watts for the 1.2-GHz chip.
The Power4+ is a 0.13-micron version of its existing Power4 processor line, which is based on 0.18-micron technology. The Power4+ is said to be 35% smaller in terms of die size than the Power4, according to the Armonk-based computer giant.
The processor architecture is key to IBM's server strategy. The p650 server will compete against x86-based computers, based on Intel Corp.'s 32-bit Xeon or 64-bit Itanium processors.
IBM's server will also compete against RISC-based systems from HP and Sun Microsystems. IBM claims the p650 is 50% faster than comparable servers from Sun and consumes a third less power per processor than the latest version of Sun's UltraSPARC III processor.
