The AMD Opteron 8350 was a server/workstation processor with 4 cores, launched in September 2007, at an MSRP of $1019. It is part of the Opteron lineup, using the Barcelona architecture with Socket Fr2. To further increase overall system performance, up to eight Opteron 8350 CPUs can link up in a multi-processor (SMP) configuration. Opteron 8350 has 2 MB of L3 cache and operates at 2000 MHz. AMD is building the Opteron 8350 on a 65 nm production process using 463 million transistors. The multiplier is locked on Opteron 8350, which limits its overclocking capabilities. With a TDP of 95 W, the Opteron 8350 consumes a good deal of power, so decent cooling is needed. AMD's processor supports DDR2 memory with a dual-channel interface. The highest officially supported memory speed is 667 MT/s. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. Actual memory technology support depends on the chosen motherboard, the processor itself supports multiple memory types, but most motherboards have only one kind of slot. This processor lacks integrated graphics, you might need a graphics card. Hardware virtualization is available on the Opteron 8350, which greatly improves virtual machine performance.

AMD's "ACP" or Average Core Power ratings exist to, "reflect the CPU power consumption running typical data center workloads" according to AMD. The number is a geometric mean of power consumed running TPC-C, SPECcpu2006, SPECjbb2005, and Stream.
