3 Processor

AMD Opteron 4100, 4200 and 4300 series processors, part of the AMD Opteron 4000 series
platform, offer the world's lowest power-per-core server processor, setting the foundation for cloud
workloads and affordability for mainstream infrastructure servers. AMD power-efficient server
processor designs are the first to break the six watt per core barrier. Compared to previous
generations, these designs allow customers to double the number of servers within the same power
budget.

Processor features

Features of the AMD Opteron 4200/4300 series include:

32nm process technology

Eight "Piledriver" processor cores (256b FPU)

New ISA extensions

Up to 16MB combined L2 + L3 cache

Two DDR3 memory channels supporting RDIMM and UDIMM

Two HyperTransport technology 3.0 links up to 6.4GT/s

Advanced Platform Management Link (APML) for system management

Increased frequency

Four to eight cores per processor

Same thermal support as previous generations

Supports 12 DIMMs in 2-socket servers such as the PowerEdge C6105

New "Piledriver" per clock instructions

Increased performance and power efficiency versus previous 4200 series processors

Compatible with C32 socket; requires a BIOS update

AMD Opteron 4000 series processor features
Function
Provides an interface for
processor and systems
management monitoring
and controlling of system
resources (in APML-
enabled platforms);
comprised of the Remote
Power Management
Interface (RPMI) and the
precision thermal
monitor
Benefits
RPMI in APML enabled platforms:

Ability to monitor and control
platform power consumption through
p-state limits

Access to processor identification and
health
Precision thermal monitor:

Accurate information about
processor thermals to closely monitor
power/cooling and proactively alert
the BMC

Early notification helps save time and
money by providing intelligence to
more effectively monitor power and
thermals to optimize cooling
