Staying Single Costs More

AMD reckons 500 Intel Nocona Xeon processors, each drawing around 111w, cost more than $84,000 (£44,000 approx) a year to run at Californian prices. As a result, cutting the power drain on processors can save big organisations a lot of money.

The relatively low UK price of 4.1p per kilowatt-hour for large users still works out at just under £50 for a 24-hour day, or nearly £18,000 a year, for 500 100w CPUs. So a 30 per cent reduction in power drain could save tens of thousands a year for organisations with lots of PCs.

Heat is a major issue in big installations where blade servers are stacked in racks. Dual-core means companies can increase power for the same ‘thermal envelope’ or reduce the heat for the same computing power.
