Differences between Dell OptiPlex M Plus 7020 2024 and HP EliteDesk 800 G6 Tower

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex M Plus 7020 2024 which was released in 2024. The HP EliteDesk 800 G6 Tower is older and entered production in 2020.

If you are looking for the smaller form factor the Dell OptiPlex M Plus 7020 2024 is the right one for you. It is smaller than the HP EliteDesk 800 G6 Tower and will fit more easily under your desk.

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 Dell OptiPlex M Plus 7020 2024 as it is running a newer generation CPU. This is not to say that HP EliteDesk 800 G6 Tower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The HP EliteDesk 800 G6 Tower has 4 RAM slots while the Dell OptiPlex M Plus 7020 2024 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 Dell OptiPlex M Plus 7020 2024 is using the faster 5600 MT/s RAM. The HP EliteDesk 800 G6 Tower is slower by supporting RAM speeds of up to 2933 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G6 Tower as it has the ability to run 128 GB of RAM. The Dell OptiPlex M Plus 7020 2024 can do a bit less at max 64 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the HP EliteDesk 800 G6 Tower has 11 USB ports. The Dell OptiPlex M Plus 7020 2024 is inferior in this regard and packs 5 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. It's great that both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. But if you need maximum connectivity, go with the HP EliteDesk 800 G6 Tower as it has 5 USB3.1 ports (the Dell OptiPlex M Plus 7020 2024 has 3).

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex M Plus 7020 2024 comes with 3 ports, while the HP EliteDesk 800 G6 Tower has only 2. If you are planning to use multiple monitors, the Dell OptiPlex M Plus 7020 2024 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 HP EliteDesk 800 G6 Tower is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex M Plus 7020 2024 has 0 slot(s).

When your goal is to have the fastest SSD transfer speeds, an M.2 interface is crucial. Thus, it is good that both models have M.2 SSD slots. Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to invest in SATA drives anymore.

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 M Plus 7020 2024 comes with a decent 180 Watt PSU, but the HP EliteDesk 800 G6 Tower has a more powerful one rated at 550 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.
