Differences between Dell OptiPlex 7090 MT and HP EliteDesk 800 G8 Mini

Both computers, the Dell OptiPlex 7090 MT and the HP EliteDesk 800 G8 Mini, were released during the same year - 2021.

If you are looking for the smaller form factor the HP EliteDesk 800 G8 Mini is the right one for you. It is smaller than the Dell OptiPlex 7090 MT and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 11 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 Dell OptiPlex 7090 MT has 4 RAM slots while the HP EliteDesk 800 G8 Mini 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 3200. In addition, you will be able to install the same amount of RAM in both models, and most probably 128 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.

Ports

In total the HP EliteDesk 800 G8 Mini has 10 USB ports. The Dell OptiPlex 7090 MT is inferior in this regard and packs 9 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. Both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. This is especially crucial if you are using external drives on a regular basis.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 7090 MT comes with 4 ports, while the HP EliteDesk 800 G8 Mini has only 2. If you are planning to use multiple monitors, the Dell OptiPlex 7090 MT is the better choice.

The Dell OptiPlex 7090 MT comes with an HDMI port, while the HP EliteDesk 800 G8 Mini does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).

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 7090 MT is better equipped as it comes with 4 SATA slot(s), while the HP EliteDesk 800 G8 Mini 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 HP EliteDesk 800 G8 Mini comes with a decent 90 Watt PSU, but the Dell OptiPlex 7090 MT has a more powerful one rated at 500 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.
