HP ProLiant AMD-based 300-series G7 servers

Processor technology
The HP AMD-based 300-series G7 servers use the AMD Opteron 6100 series eight- and twelve-core
processors allowing up to 24 cores in a two-processor platform. These processors are based on
AMD's 45 nanometer process and have a core standard wattage of 75W Average CPU Power. In
addition, these processors use Direct Connect™ architecture 2.0, HyperTransport™ 3.0, HT Assist™,
and 8x ECC error correction. The 6100 processors fit into the G34 socket infrastructure and feature
DDR3 memory, four 64 bit memory channels per processor, the AMD SR5690/SP5100 chipset, and
quad HyperTransport (HT) links as shown in Figure 1. The processors operate at speeds of up to 2.4
GHz with eight cores and 2.3 GHz with twelve cores. They access 512 KB of L2 cache memory per
core and share a 12 MB L3 cache. The AMD Opteron 6100 series processor includes performance-
optimized power and thermal controls. See the Power and thermal technologies
section for more
information.

NOTE:
In this AMD Opteron 6100-series architecture, the SR5690 (sometimes referred to as
the Northbridge chip) is responsible for I/O and PCI devices, while the SR5100
(sometimes referred to as the Southbridge chip) is responsible for USB, CD/DVD, and
video functions
