All Opteron Models | Hardware Secrets

As mentioned before, Opteron processors from 2xx series support multiprocessing with two CPUs and have two HyperTransport busses. These models are based on socket 940 and required registered (buffered) DDR memories, which are a special kind of memory targeted to servers. “HE” models have lower power consumption.

Below you can find all Opteron 2xx models released to date. TDP stands for Thermal Design Power and indicates the CPU maximum thermal dissipation, i.e., the CPU cooler must be able to dissipate at least this amount of heat.
