AMD is shipping new B3 versions of its low-power quad-core Opteron processors.
AMD first released details of these processors in September 2007, when it unveiled the quad-core Opteron processor. However, earlier versions of the chips were affected by a bug discovered in December that reportedly forced AMD to suspend some processor shipments. The B3 version of the chips fix that bug.
The five chips run at clock speeds ranging from 1.7GHz to 1.9GHz. Three of the chips - the 2344 HE, 2346 HE and 2347HE - are designed for servers with two processors, while the other two - the 8346 HE and 8347 HE - can be used in servers with four or eight processors. They are priced from $255 to $873 (£127 to £436) in 1,000-unit quantities, a standard way of quoting chip prices.
The low-power quad-core Opteron chips have an average power consumption of 55W, AMD has said.
