The AMD Opteron 3320 EE is a server/workstation processor with 4 cores, launched in December 2012. It is part of the Opteron lineup, using the Delhi architecture with Socket AM3+. Opteron 3320 EE has 8 MB of L3 cache and operates at 1900 MHz by default, but can boost up to 2.5 GHz, depending on the workload. AMD is making the Opteron 3320 EE on a 32 nm production node using 1,200 million transistors. The multiplier is locked on Opteron 3320 EE, which limits its overclocking potential.
With a TDP of 25 W, the Opteron 3320 EE consumes only little energy. AMD's processor supports DDR3 memory with a dual-channel interface. For communication with other components in the computer, Opteron 3320 EE uses a PCI-Express Gen 2 connection. Although neither the processor nor its chipsets support integrated graphics, certain motherboards include dedicated graphics chipset that can provide some basic display output functionality.
Hardware virtualization is available on the Opteron 3320 EE, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications.
