Power vs. ARM
The Power architecture is likely to have higher performance but also
higher power consumption than ARM-based SoCs. Currently, at least five
companies are designing ARM-based server SoCs, including Applied Micro,
which has a background with the Power architecture in communications
chips. The company nevertheless opted for a 64-bit custom ARM core for
its upcoming XGene server chips.
Other ARM server SoC makers
include startup Calxeda, which has a 32-bit chip now shipping in systems
and a 64-bit chip planned for 2014. Dell is using Marvell’s 32-bit
Armada XP chip in servers. Cavium has announced plans for 64-bit ARM
server SoCs and Samsung reportedly also has a project in the works.
recently announced a family of low power servers designed to use a
variety of CPU architectures. It picked Intel’s dual-core Atom server
chip, Centerton, for the first member of the family.
press release contained general comments praising the startup from
leaders of the Power.org group and the Linux Foundation. The news comes
one week before the opening of the annual ARM Tech Con
at which Applied is expected to give the first demo of an ASIC version of its 64-bit XGene.
