The SR950 supports the Gold and Platinum level processors in the Intel Xeon Processor Scalable Family, including the "top bin" highest performing 205 W processors available from Intel.

The server supports up to four or eight processors, depending on the configuration selected, however processors are all installed within the 4U rack enclosure:

- For configurations that support up to eight processors, the server supports 2, 4 or 8 processors. (There is no support for 6-processor configurations. )
- For configurations of up to four processors (lower cost configuration, no upgrade path to eight processors), the server supports 2 or 4 processors
