The Dell OptiPlex SFF 7020 2024 is using the faster 5600 MT/s RAM. The HP EliteDesk 800 G4 Mini is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex SFF 7020 2024 as it has the ability to run 64 GB of RAM. The HP EliteDesk 800 G4 Mini can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.

In total the Dell OptiPlex SFF 7020 2024 has 8 USB ports. The HP EliteDesk 800 G4 Mini is inferior in this regard and packs 7 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. 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 SFF 7020 2024 has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP EliteDesk 800 G4 Mini comes with 2 ports, while the Dell OptiPlex SFF 7020 2024 has only 1. If you are planning to use multiple monitors, the HP EliteDesk 800 G4 Mini is the better choice.

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 Dell OptiPlex SFF 7020 2024 is better equipped as it comes with 2 SATA slot(s), while the HP EliteDesk 800 G4 Mini has 1 slot(s).
An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the HP EliteDesk 800 G4 Mini has 1 M.2 slots while the Dell OptiPlex SFF 7020 2024 comes with just 1.
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 HP EliteDesk 800 G4 Mini comes with a decent 150 Watt PSU, but the Dell OptiPlex SFF 7020 2024 has a more powerful one rated at 300 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.
