While Intel may already be worried about ever gaining a foothold in the mobile chip market. ARM is starting to push into the high-end server market too with news of a 480-core, low power server in the works.The company behind the new server is a data center startup called Calxeda. Its focus is on building a processor platform that will have a significant impact on IT costs and energy consumption. They go so far as to claim a factor of 10 reduction in costs and a 5x, or even 10x performance gain over what is currently available.In order to produce hardware capable of reducing power consumption by such a large extent, the company has turned like so many others to ARM for its chips. It plans to develop a server consisting of up to 120 quad-core ARM Cortex-A9 processors, which means as many as 480 available cores.As for power use, when combined with DRAM Calxeda believes each node in the server will draw just 5 watts, or 1.25 watts per core. It is hoped that such a low power configuration combined with the proven performance on offer from the Cortex-A9 and so many cores, will be desirable to data centers.As for when this server configuration will be ready, Calxeda isn’t saying yet and remains in stealth mode as a company for the moment.Read more at Computerworld and Richard Fichera’s Blog (image courtesy of Wikipedia)Matthew’s OpinionARM’s latest mobile processors offer up enough performance to make them viable for smartphones (as can already be seen in the marketplace), for use in netbooks and, according to Calxeda, for servers too. As we’ve already seen in the most recent smartphones, the chips are fast and still allow many hours of battery life demonstrating their low power draw. Low power also means less heat therefore having an impact on the amount of cooling required for these new servers.While Intel is too big and established to be on its back foot just yet, the growing use of ARM designs in the processor market must surely have the chip design company on its radar. One of the biggest breakthroughs for making ARM chips a mainstream computing option was the news earlier this year that Windows 8 will support the architecture. Add to that a forthcoming 2.5GHz Snapdragon processor and we’re in for some exciting times ahead as consumers.And if you’re wondering what performance is like compared to the Intel Atom chip, the Cortex-A9 can compete with a 1.6GHz Atom even when running at 500MHz. Now imagine what is going to happen when you have Atom-based servers (which Microsoft is already asking for) competing for data center space next to a Cortex-A9 server. The one sure outcome of this is more processing power coupled with lower prices on the hardware side as these two chip companies go to war.
