The Opteron 4386 3.1 GHz 6-Core Processor from AMD is designed to support workloads for IT organizations of all sizes. This includes server rooms, data centers, traditional IT shops, cloud providers, and more. It has been optimized for virtualization and features a base clock speed of 3.1 GHz, a max clock speed of 3.8 GHz, 8 processing cores, 8MB of shared L3 cache, 1MB of L2 cache per core (8MB total), a 95W TDP, and fits in a C32 socket. The Opteron 4386 also supports DDR3-1866 MHz RAM with voltages of 1.25 and 1.35V and has a 256-bit FPU.
Modular Core Architecture
Optimized performance per watt:
High-frequency and low-power design
Shared double-sized Flex FP
The processor core can help enhance power efficiency for server products:
Help minimize cooling solution complexities.
Help reduce power at low utilization.
Enable more control for IT managers
AMD Turbo CORE Technology
Helps turn unused TDP headroom into added clock speed for improved performance. The full-core boost provides up to a 300 MHz frequency increase
A flexible 256-bit FPU with two 128-bit FMACs shared per module, allowing for dedicated 128-bit execution per core or shared 256-bit execution per module. This helps enhance flexibility and performance in technical computing
DDR3-1866 MHz support for memory intensive applications
APML (Advanced Platform Management Link)
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.
Remote Power Management Interface (RPMI) in:
Ability to monitor and control platform power consumption via p-state limits
Access to processor identification and health
Precision Thermal Monitor:
Provides information about CPU thermals to closely monitor power/cooling and proactively alert the Base Management Controller (BMC)
Early notification helps save time and money by providing intelligence that can be used to effectively monitor power and thermals to optimize cooling solutions in an IT datacenter
TDP Power Cap
Allows the user to set the maximum processor power ceiling via BIOS or APML. This technology gives enterprises the ability to customize their chips to meet power and workload demands, providing:
More control over power settings
Flexibility to set power limits without capping CPU frequencies
AMD CoolSpeed Technology
Helps Protect processor integrity by reducing power-states when a temperature limit is reached
A server can automatically drop into lower power mode if the processor's thermal environment exceeds safe operational limits
Offers platform providers the ability to safely reduce system fan speeds, which helps deliver greater platform efficiency
Helps reduce memory controller and HyperTransport technology links' power. This feature can equate to power savings in your datacenter depending on system configuration, when the Northbridge and HyperTransport technology links are powered down and cores are at idle
Core power gating: When a core is halted, its context is exported to system memory and voltage is removed from the core. This helps reduce power consumption at idle to minimize energy consumption when servers are not in use
Supports 1.25V and 1.35V DDR3, which helps to reduce overall power consumption
Specialized ultra-low power platforms work well for cloud/dense environments. Cooperative designs for specialized and ultra-low power platform help provide power efficiency beyond just the processor
Direct Connect Architecture 2.0
HyperTransport Technology Assist (HT Assist)
Helps to increase coherent memory bandwidth and reduce latency in multi-node systems by reducing cache probe traffic between cores. This helps to reduce the amount of cache probe bus traffic enhancing a server's efficiency and scalability
HyperTransport 3.0 Technology (HT3)
Provides increased system bandwidth between CPUs and I/O, helping to increase the interconnect rate up to a maximum 6.4 GT/s with HT3. This helps improve overall system balance and scalability
