Differences between Dell OptiPlex 9020 USFF and Fujitsu Esprimo P520

If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo P520 which was released in 2014. The Dell OptiPlex 9020 USFF is older and entered production in 2013.

If you are looking for the smaller form factor the Dell OptiPlex 9020 USFF is the right one for you. It is smaller than the Fujitsu Esprimo P520 and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 4 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.

Memory

The Fujitsu Esprimo P520 has 4 RAM slots while the Dell OptiPlex 9020 USFF has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.

None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 1600. Additionally, if you will be needing a lot of RAM, better go for the Fujitsu Esprimo P520 as it has the ability to run 32 GB of RAM. The Dell OptiPlex 9020 USFF can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the Fujitsu Esprimo P520 has 8 USB ports. The Dell OptiPlex 9020 USFF is inferior in this regard and packs 6 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 9020 USFF comes with 2 ports, while the Fujitsu Esprimo P520 has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 9020 USFF is the better choice.

None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.

SATA ports are placed on the system board and it is where you connect your HDD, SSD and Optical Disk Drives. More SATA slots will allow you to have more drives running at the same time. In this regard the Fujitsu Esprimo P520 is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 9020 USFF has 2 slot(s).

If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the Dell OptiPlex 9020 USFF. Sadly, the Fujitsu Esprimo P520 has no such slot, and you will be forced to use the SATA interface instead.

Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6Gb/s, while the PCIe 3.0 x4 will support speeds up to 32Gb/s!

Power Supply

Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The Dell OptiPlex 9020 USFF comes with a decent 200 Watt PSU, but the Fujitsu Esprimo P520 has a more powerful one rated at 280 Watts. Choosing either one depends on your specific requirements and use case. Also don't forget that some models might have more than one PSU option - try to always get the most powerful one, especially if you plan to upgrade to a powerful GPU.
