Overview

The AMD G34 is designed specifically for high-end server applications. The processor
features up to twelve-core processing to maximize performance and
performance/watt for data center infrastructures and highly dense deployments. The
G34 processor also features AMD Opteron micro-architecture and AMD64 architecture
for flexibility in 64-bit and 32-bit applications and operating
The G34 processor utilizes a 1944-contact Organic Land Grid Array (OLGA) package
that plugs into a surface-mount socket (Socket-G34). The PowerEdge R815 provides
support for up to four G34 processors. See Table 7.
