AMD today unveiled nine new mid-range and entry-level AMD Opteron 4300 Series and 3300 Series server processors increasing performance per watt versus the previous generation, targeted for use in cloud servers that process Web transactions. The new Opteron 4300 and 3300 x86 server chips have up to eight cores and are targeted at entry-level and mid-range servers.

The AMD Opteron 4300 Series processors offer up to 15 percent better performance versus AMD's prior generation, based on AMD SPECint benchmark results. And SPECpower results show up to a 24 percent improvement in performance per watt. As with the AMD Opteron 6300 Series processors, these are socket compatible with the previous generation processor.

"The Piledriver core architecture shared by the AMD Opteron 4300 and 3300 Series processors provides optimized performance, power and price for today's customer," said Suresh Gopalakrishnan, general manager, Server Business Unit, AMD. "These new processors are ideal for cloud providers, web hosts and small- and medium-sized businesses who want to address their space and power constraints. With a simple upgrade, existing customers can obtain more performance and improved energy efficiency and new customers will obtain compelling value and ROI."

Servers based on the new processors are now available from Supermicro as well as the AMD SeaMicro SM15000 platform. Additional server offerings will soon be available from Dell and others.

AMD Opteron 4300 series processors offer up eight cores clocked at up to 3.4 GHz (base frequency) and up to 3.8 GHz using AMD Turbo CORE technology They draw between 35 watts and 65 watts of power and support AMD Virtualization (AMD-V) technology and AMD-P power management features. The new chips have two memory channels support of up to 1866 MHz memory. Up to six DIMMs per CPU can be used to add up to 192GB memory per processor. Two x16 HyperTransport technology (HT3) links offer up to 6.4GT/s per link.

The AMD Opteron 3300 processors also have up to eight cores per socket clocked at up to 2.8 GHz (3.8 GHz using AMD Turbo CORE technology.) They draw as little as 25W of power and have two memory channels with up to 1866 MHz memory support. Up to four DIMMs are available for each CPU for up to 32GB memory per processor. The 3300 series also support AMD Virtualization (AMD-V) technology, AMD-P power management features and feature one x16 HyperTransport technology (HT3) link at up to 5.2GT/s.
