5 Processors

5.1 Overview

The AMD G34 processor is designed specifically for high-end server applications. The processor

features up to twelve-core processing to maximize performance and performance/watt for

datacenter infrastructures and highly dense deployments. The G34 processor also features AMD’s

Opteron micro-architecture and AMD64 architecture for flexibility in 64-bit and 32-bit applications

and operating systems.

The G34 processor utilizes a 1944-contact Organic Land Grid Array (OLGA) package that plugs into a

surface mount socket (Socket-G34). R715 provides support for up to two G34 processors. See Table 8.
