Precision T5820 Xeon W-2135 20-core workstation

The Dell Precision T5820 is a new rackmount workstation built around a single Intel Xeon W-2135 processor running at 3.70GHz with 20 cores. It ships with 64GB of DDR4-2666 memory and supports up to 512GB total. Four 3.5-inch SAS/SATA expansion bays are available for storage configuration.

Suits CPU-heavy professional workloads.

This system suits engineers, designers and data specialists who need high core-count CPU performance for rendering, simulation or multi-threaded analysis. It is not for buyers who require a pre-installed graphics card, an operating system or storage drives, as none are included. Buyers needing more than one physical processor should also look elsewhere.

Single Xeon W-2135 in LGA3647 socket limits to one

The workstation accommodates exactly one processor in its LGA3647 socket and the maximum supported count is one. This fixed single-socket design defines the platform ceiling for multi-threaded throughput and memory capacity. Verify that your software licensing and workload scaling align with this constraint before purchase.

Questions about this item

How is the Xeon W-2135 installed in the Precision T5820 and which step is often missed?

The W-2135 seats in the LGA3647 socket with a single processor limit; the step often missed is applying the correct torque to the retention bracket before closing the load plate.

What maintenance or replacement will the 64GB DDR4 2666MHz memory need later?

Memory can be expanded to 512GB using DDR4 2666MHz modules; plan to add matched DIMMs in sets of four for optimal channel population.

Which limit appears first under sustained load with four 3.5" SAS/SATA bays populated?

Drive thermal throttling typically appears first; the four 3.5" bays share limited front-to-rear airflow, so sustained writes can push bay temperatures above safe thresholds.
