DellPowerEdge R715 Technical Guide 265 Processors5.1 OverviewThe AMD G34 processor is designed specifically for high-end server applications. The processorfeatures up to twelve-core processing to maximize performance and performance/watt fordatacenter infrastructures and highly dense deployments. The G34 processor also features AMD’sOpteron micro-architecture and AMD64 architecture for flexibility in 64-bit and 32-bit applicationsand operating systems.The G34 processor utilizes a 1944-contact Organic Land Grid Array (OLGA) package that plugs into asurface mount socket (Socket-G34). R715 provides support for up to two G34 processors. See Table 8.Table 8.
