Processors
The following table lists the details of the processors supported by your OptiPlex 5490:
NOTE: Global Standard Products (GSP) are a subset of Dell’s relationship products that are managed for availability and
synchronized transitions on a worldwide basis. They ensure that 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.
Device Guard (DG) and Credential Guard (CG) are the new security features that only available on Windows 10 Enterprise
today. Device Guard is a combination of enterprise-related hardware and software security features. When you configure
together, it locks a device down so that it can only run trusted applications. If it is not a trusted application, it cannot run.
Credential Guard uses virtualization-based security to isolate secrets (credentials) so that only privileged system software can
access them. Unauthorized access to these secrets can lead to credential theft attacks. Credential Guard prevents these
attacks by protecting NTLM password hashes and Kerberos Ticket Granting Tickets.
NOTE: Processor numbers are not a measure of performance. Processor availability subject to change and may vary by
region/country.

Commercial platform Windows 10 N-2 and 5-year operating system supportability:
All newly introduced 2019 and later commercial platforms (Latitude, OptiPlex, and Dell Precision) will qualify and ship with the
most current factory installed Semi-Annual Channel Windows 10 version (N) and qualify (but not ship) the previous two versions
(N-1, N-2). The OptiPlex 5490 All-in-One will RTS with Windows 10 version v20H2 at time of launch, and this version will
determine the N-2 versions that are initially qualified for this platform.
For future versions of Windows 10, Dell continues to test the commercial platform with coming Windows 10 releases during
device production and for five years post-production, including both fall and spring releases from Microsoft.
