The Opteron 6348 2.8 GHz 12-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 2.8 GHz, a max clock speed of 3.4 GHz, 12 processing cores, 16MB of shared L3 cache per socket, 1MB of L2 cache per core (for a total of 12MB), a TDP of 115W, and G34 socket compatibility. The Opteron 6348 also supports DDR3-1866/1600 MHz RAM with voltages of 1.25 and 1.35V.
2nd Generation of AMD's Core Architechture - "Piledriver"
Improved performance and performance/watt than the previous generation
Same power bands and power saving features
This helps provides a lower TCO with improved performance. It also helps run applications faster within the same power budget and helps extend the life of your investment by leveraging current socket platforms
Cache and Core Count
12 cores, 1 MB of L2 cache per core (12 MB total), and 16 MB of shared L3 cache per socket. This helps improves performance and performance/watt for multi-threaded environments like virtualization, database, and web serving
Supports DDR3-1600 for typical memory configurations and DDR3-1866 for slightly loaded memory configurations. This helps to improve system performance
Quad Channel Memory
Four DDR3 memory channels with max memory bandwidth of up to 51.2 GB/s @ DDR3-1600 with RDIMM, LRDIMM, LV RDIMM, and UDIMM. This can help to increase performance, especially in memory-intensive workloads
AMD Turbo CORE Technology
Twelve cores can boost performance by up to 300 MHz simultaneously when headroom is available. This helps add clock speed for improved performance
AES Instructions provide hardware acceleration for fast and secure data encryption and decryption. This helps improve application performance
TDP Power Cap
Thermal design power (TDP) can be set in one watt increments using the BIOS or APML to get the most processing power into a single rack. This helps offer more control over power settings and the flexibility to set power limits without capping CPU frequencies
C6 Power State
Core power gating reduces and increases voltage as needed. This helps reduce power costs during times of low usage
APML (Advanced Platform Management Link)
Enables monitoring and controlling of system resources via a Remote Power Management Interface (RPMI) and Precision Thermal Monitor(in APML-enabled platforms). This helps to remotely monitor and control power and cooling
AMD CoolSpeed Technology
The server automatically drops into lower power mode if processor's temperature exceeds safe operational limits. Platform providers can safely reduce system fan speeds to deliver greater platform efficiency. This helps protect the processor from overheating
C1E reduces power to the memory controller and HyperTransport technology links. This helps reduce power consumption
This enables extremely dense memory configurations and helps reduce memory-bottlenecks in memory intensive environments such as virtualization
Direct Connect Architecture 2.0
HyperTransport Technology Assist
This helps to increase coherent memory bandwidth and reduces latency in multi-node systems by reducing cache probe traffic between cores, helping to improve system efficiency and scalability
HyperTransport 3.0 Technology (HT3)
Provides increased system bandwidth between CPUs and I/O, increasing the interconnect rate up to a maximum 6.4 GT/s with HT3. This helps improve system balance and scalability
AMD-V 2.0 Technology
AMD Virtualization (AMD-V) 2.0 Technology
Tagged TLB - Efficient switching between virtual machines for better application responsiveness
AMD-V Technology Extended Migration - Helps enable live migration of VMs between all available AMD Opteron processor generations
I/O Virtualization - Enables direct device access by a virtual machine for increased integrity and security
This technology is easy to deploy and the larger pool of resources helps enable greater VM consolidation. It is also easy to manage with common architecture helping to simplify the managing of virtual pools. It is also easy to move, as extended migration helps deliver increased flexibility for load balancing and disaster recovery
