The AMD Opteron 6274 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 two Opteron 6274 CPUs can link up in a multi-processor (SMP) configuration. Opteron 6274 has 16 MB of L3 cache and operates at 2.2 GHz by default, but can boost up to 3.1 GHz, depending on the workload. AMD is building the Opteron 6274 on a 32 nm production process using 2,400 million transistors. The multiplier is locked on Opteron 6274, which limits its overclocking capabilities.
With a TDP of 115 W, the Opteron 6274 consumes a lot of power, so good cooling is definitely needed. AMD's processor supports DDR3 memory. For communication with other components in the machine, Opteron 6274 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 6274, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
