Intel has introduced more single-core Xeon processors, which consume less power and reduce overheating in datacentres.
The processors are the 55-watt, 3GHz Xeon LV and the 90-watt, 3.2GHz Xeon MV. Intel's conventional 3.8GHz dual-core Xeon processors operate at 110 watts.
The new chips are designed for blade servers and other tightly packed server configurations that can give off large amounts of heat, resulting in bigger electricity bills from air conditioning systems working flat-out.
Dell recently announced it would be selling its first servers equipped with the dual-core Xeon processors from next month. Like Intel, the company is expected to offer single-core models as well.
