AMD added a pair of low power processors to its Opteron 6300 parts. Previously codenamed “Warsaw,” the 12- and 16-core CPUs are largely aimed at customers who run large private cloud computing environments. AMD claims the processors will “deliver improved performance per watt for virtualized private cloud deployments with less power and at lower cost.”
These lower-power versions of the Opteron both have a thermal design power (TDP) of 99W compared to the TDP of 115W of AMD’s Opteron 6380 and the 140W of the Opteron 6386 SE. While they run at a lower clock speed than those higher-power processors, they cost significantly less and offer about 27 percent more performance per watt than the previous generation of Opteron 6300s, according to Supermicro. The 16-core 6370P runs at a base of 2.0GHz with a “turbo” mode up to 2.5GHz and the 12-core 6338P runs at 2.3GHz with a 2.8GHz turbo. Apart from the clock speeds and TDPs, the new processors share the same Piledriver cores, 32nm fabrication process, cache configurations, and dual-die design that their high-power siblings sport.
The 16-core Opteron 6370P is priced at $598, and the 12-core 6338P goes for $377. Both are available today through the system integrators Avnet and Penguin, and they are shipping in servers from Supermicro and Sugon as well. AMD clearly hopes they will get the attention of big data center owners like Facebook and Google, and it is promoting the CPUs as candidates for Open Compute Platform open source hardware servers on AMD’s Open 3.0 OCP offering. But the processors could also be attractive to companies looking to build small, inexpensive private clouds for their virtual server farms.
