The AMD Opteron 4276 HE was a server/workstation processor with 8 cores, launched in June 2012, at an MSRP of $455. It is part of the Opteron lineup, using the Valencia architecture with Socket C32. To further increase overall system performance, up to two Opteron 4276 HE CPUs can link up in a multi-processor (SMP) configuration. Opteron 4276 HE has 8 MB of L3 cache and operates at 2.6 GHz by default, but can boost up to 3.6 GHz, depending on the workload. AMD is building the Opteron 4276 HE on a 32 nm production process using 1,200 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. The multiplier is locked on Opteron 4276 HE, which limits its overclocking capabilities.
With a TDP of 65 W, the Opteron 4276 HE consumes typical power levels for a modern PC. AMD's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1600 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the machine, Opteron 4276 HE 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 4276 HE, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
