Differences between Dell OptiPlex 9020 USFF and HP EliteDesk 800 G4 Mini

If a more modern desktop is what you are looking for, then you should go with the HP EliteDesk 800 G4 Mini which was released in 2018. The Dell OptiPlex 9020 USFF is older and entered production in 2013.

Processor

Usually the newer the generation of the CPU, the better the performance and efficiency is. If your budget allows it, you should go with the HP EliteDesk 800 G4 Mini as it is running a newer generation CPU. This is not to say that Dell OptiPlex 9020 USFF is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

RAM slots is where your insert your RAM sticks. Each of those two models has 2 RAM slot(s) which should be taken into account when planning how much and what combination of RAM you are going to need.

The HP EliteDesk 800 G4 Mini is using the faster 2666 MT/s RAM. The Dell OptiPlex 9020 USFF is slower by supporting RAM speeds of only up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G4 Mini 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 most users.

Ports

In total the HP EliteDesk 800 G4 Mini has 7 USB ports. The Dell OptiPlex 9020 USFF is inferior in this regard and packs 6 USB ports. What is nice about the HP EliteDesk 800 G4 Mini, is that it has 4 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 9020 USFF has no such port, thus restricting your transfer speeds a bit.

The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. It is good to see that both of the models come with a DisplayPort.

None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter.

SATA port 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 Dell OptiPlex 9020 USFF is better equipped as it comes with 2 SATA 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 HP EliteDesk 800 G4 Mini. Sadly, the Dell OptiPlex 9020 USFF has no such slot, and you will be forced to use the SATA interface instead.

Remark: Make sure that the M.2 slot supports the PCIe (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 6 Gb/s, while the PCIe 3.0 x4 will support speeds up to 32 Gb/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 HP EliteDesk 800 G4 Mini comes with a decent 150 Watt PSU, but the Dell OptiPlex 9020 USFF has a more powerful one rated at 200 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.
