Differences between Dell OptiPlex 9020 MT and HP ProDesk 400 G4 Microtower

If you are looking for a more modern desktop, then you should go with the HP ProDesk 400 G4 Microtower which was released in 2017. The Dell OptiPlex 9020 MT is older and entered production in 2013.

Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.

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 ProDesk 400 G4 Microtower as it is running a newer generation CPU. This is not to say that Dell OptiPlex 9020 MT is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Dell OptiPlex 9020 MT has 4 RAM slots while the HP ProDesk 400 G4 Microtower 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.

The HP ProDesk 400 G4 Microtower is using the faster 2400 MT/s RAM. The Dell OptiPlex 9020 MT is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 400 G4 Microtower as it has the ability to run 64 GB of RAM. The Dell OptiPlex 9020 MT can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the Dell OptiPlex 9020 MT has 10 USB ports. The HP ProDesk 400 G4 Microtower is inferior in this regard and packs 8 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 MT comes with 2 ports, while the HP ProDesk 400 G4 Microtower has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 9020 MT 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 Dell OptiPlex 9020 MT is better equipped as it comes with 4 SATA slot(s), while the HP ProDesk 400 G4 Microtower has 3 slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell OptiPlex 9020 MT, nor the HP ProDesk 400 G4 Microtower has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

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 MT comes with a decent 290 Watt PSU, but the HP ProDesk 400 G4 Microtower has a more powerful one rated at 310 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.
