PR O CESSOR
NOTE: Global Standard Products (GSP) are a subset of Dell’s relationship products that are managed for availability and synchro-
nized transitions on a worldwide basis. They ensure the same platform is available for purchase globally. This allows customers to
reduce the number of configurations managed on a worldwide basis, thereby reducing their costs. They also enable companies to
implement global IT standards by locking in specific product configurations worldwide. The following GSP processors identified below
will be made available to Dell customers.
NOTE: Processor numbers are not a measure of performance. Processor availability subject to change and may vary by region/
country.
