The three Opteron 3200 chips are for use in single-socket servers for Web hosting and cloud applications, according to a company presentation. The chips have up to eight processor cores, clock speeds of up to 3GHz, and draw between 45 watts and 65 watts of power.

The new chips are based on the Bulldozer processor architecture, which is also in the Opteron 6200 16-core processors and FX-series gaming chips. The Opteron 3200 launch comes after AMD in late February announced it would pay US$334 million to acquire SeaMicro, which offers dense and power-efficient servers for cloud computing environments.

AMD's chips will likely compete against Intel's Xeon E3 series chips, which are used in SeaMicro's SM10000-XE server. Intel worked with SeaMicro on the server, but analysts have said that AMD will ultimately swap Intel's chips with its own chips.

AMD is pitching the Opteron 3200 as a "low-cost-per-core" product. The chips are priced between US$99 and $129, while Intel's E3 chips are priced between $189 and $885. MSI, Tyan, Fujitsu and Dell are expected to launch Web servers and dense systems based on the chips.

AMD's expanded product line provides an entry point to new markets, said Jim McGregor, chief technology strategist at In-Stat.
