Dell OptiPlex 5090 MT vs. HP EliteDesk 800 G8 Tower
Comparison and Differences
Differences between Dell OptiPlex 5090 MT and HP EliteDesk 800 G8 Tower
Both computers, the Dell OptiPlex 5090 MT and the HP EliteDesk 800 G8 Tower, were released during the same year - 2021.
Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.
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
Both models have have equal amount of ram slots (4 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.
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 Tower has 11 USB ports. The Dell OptiPlex 5090 MT is inferior in this regard and packs 10 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 G8 Tower as it has 4 USB3.1 ports (the Dell OptiPlex 5090 MT has 3).
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 5090 MT comes with 4 ports, while the HP EliteDesk 800 G8 Tower has only 2. If you are planning to use multiple monitors, the Dell OptiPlex 5090 MT is the better choice.
The Dell OptiPlex 5090 MT comes with an HDMI port, while the HP EliteDesk 800 G8 Tower 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 slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 4 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
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 G8 Tower has 1 M.2 slots while the Dell OptiPlex 5090 MT 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 Dell OptiPlex 5090 MT comes with a decent 360 Watt PSU, but the HP EliteDesk 800 G8 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.
