DELL OptiPlex 9020 SFF Desktop i7-4770 3.4GHz 32GB DDR3 512GB SSD Windows 10 Pro

Compact desktop for office and study

The Dell OptiPlex 9020 SFF is a small-form-factor desktop built around a 4th Gen Intel Core i7-4770 running at 3.40 GHz. It ships with 32 GB of DDR3 memory and a 512 GB 2.5-inch SATA SSD. Windows 10 Pro 64-bit is pre-installed with a Certificate of Authenticity. A DVD±RW drive, USB keyboard and USB mouse are included in the box.

32 GB DDR3 memory capacity

The single specification that determines suitability is the installed 32 GB of DDR3 RAM. This amount supports heavy multitasking, multiple browser tabs and typical business applications without paging. The platform uses DDR3 technology only; no other memory generation is compatible. Buyers who need more than 32 GB of system memory cannot expand this unit further.

Sustained thermal behaviour in a slim chassis

Under continuous load the compact case relies on the integrated Intel Graphics 4600 and the processor's stock cooler. The small form factor limits airflow, so extended compute tasks will cause the CPU to throttle to stay within thermal limits. Gigabit Ethernet and the SATA SSD maintain steady throughput, but the system is not designed for prolonged maximum-frequency operation. Buyers who need sustained peak performance without throttling should consider a larger tower platform.
