AMD launches Opteron 185, 285 and 885 processors

Sunnyvale (CA) - AMD kicks off a week that will be largely dominated by news coming out of Intel's developer forum in San Francisco. The company today announced three new versions of its Opteron workstation and server processor - which run at 2.6 GHz and remain in the 95 watt power envelope.

It isn't coincidence that AMD introduces the fifth clock speed level of its dual-core Opteron processors just one day before Intel will provide a first look on products that determine the company's near and mid-term future. It's a reminder that AMD is breathing down Intel's neck with its Opteron processor, which is responsible for a substantial portion of the market share loss Intel has experienced in recent months.

However, it isn't so much the Opteron's performance that AMD is highlighting these days. Whenever there is a chance, AMD pushes its power consumption advantage over Intel - which has reached a dramatic level in the dual-core arena. While all three new Opterons remain in the 95 watt power envelope, Intel's dual-core Xeon DP with 2.8 GHz Paxville core is listed with a thermal design power (TDP) of 135 watts. According to spec sheets posted on Intel's website, the Xeon MP 7000 series has a TDP of 165 watts, which may be caused by the 4 MB L2 cache of the higher end models of the family. The Opteron comes with just 1 MB of cache per core, but 40% less power consumption may sound very convincing to many server buyers.
