AMD is set to announce five new low-watt processors within its Opteron family of quad-core processors today. This will be the first time these processors have been available for purchase outside of systems offered by AMD's OEM partners. The new chips are part of AMD's 8300 and 2300 series. The new Opterons are all designed with a 55-watt TDP. The 8300 series processors will clock at 1.8- and 1.9GHz. The three CPUs in the 2300 series are being offered in speeds from 1.7GHz to 1.9GHz. All of the chips feature 512KB of L2 cache and 2M of shared L3 cache. Systems built around these processors are already available from HP and Dell with other major vendors expected to follow suit later this year. Prices range from $209 to $873 in 1,000-unit lots.
