AMD Opteron 6276

The AMD Opteron 6276 was a server/workstation processor with 16 cores, launched in November 2011. It is part of the Opteron lineup, using the Interlagos architecture with Socket G34. To further increase overall system performance, up to four Opteron 6276 CPUs can work together in a multi-processor (SMP) configuration. Opteron 6276 has 8MB of L3 cache and operates at 2.3 GHz by default, but can boost up to 3.2 GHz, depending on the workload. AMD is making the Opteron 6276 on a 32 nm production node using 2,400 million transistors. The multiplier is locked on Opteron 6276, which limits its overclocking potential. With a TDP of 115 W, the Opteron 6276 consumes a lot of power, so good cooling is definitely needed. AMD's processor supports DDR3 memory. For communication with other components in the system, Opteron 6276 uses a PCI-Express Gen 2 connection. This processor lacks integrated graphics, you might need a graphics card. Hardware virtualization is available on the Opteron 6276, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications.
