DELL OptiPlex 790 SFF Desktop PC i3-2100 3.10GHz 4GB DDR3 320GB

Small Form Factor Business Desktop

The Dell OptiPlex 790 SFF is a compact business desktop built around an Intel Core i3-2100 dual-core processor running at 3.10 GHz. It ships with 4 GB of DDR3 memory and a 320 GB hard drive. Windows 7 Professional 64-bit is pre-installed. The small form factor chassis fits tight office spaces while providing a DVD-RW drive and integrated Gigabit Ethernet.

Dual-Core Processor with 3 MB Smart Cache

The single specification that determines suitability is the Intel Core i3-2100 CPU. It delivers two cores at 3.10 GHz with 3 MB of Intel Smart Cache and 64-bit architecture. This configuration handles typical office applications and light multitasking. Buyers who need more cores, higher clock speeds or a newer instruction set for modern workloads should look elsewhere.

Sustained Office Workloads

Under continuous load the i3-2100 maintains its base 3.10 GHz frequency without thermal throttling in the SFF chassis. The integrated Intel HD Graphics 2000 shares system memory, so extended graphical tasks reduce the 4 GB DDR3 available to applications. The 320 GB hard drive provides consistent throughput for sequential reads but slows during heavy random I/O. The DVD-RW and Gigabit Ethernet remain responsive during prolonged use.
