HP EliteDesk 800 G4 SFF vs. HP ProDesk 400 G5 Mini
Comparison and Differences
Differences between HP EliteDesk 800 G4 SFF and HP ProDesk 400 G5 Mini
Both computers, the HP EliteDesk 800 G4 SFF and the HP ProDesk 400 G5 Mini, were released during the same year - 2018.
If you are looking for the smaller form factor the HP ProDesk 400 G5 Mini is the right one for you. It is smaller than the HP EliteDesk 800 G4 SFF and will fit more easily under your desk.
Processor
The two models have the same generation of Intel processors. We think that the 8 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 HP EliteDesk 800 G4 SFF has 4 RAM slots while the HP ProDesk 400 G5 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 2666. In addition, you will be able to install the same amount of RAM in both models, and most probably 64 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 G4 SFF has 11 USB ports. The HP ProDesk 400 G5 Mini is inferior in this regard and packs 6 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 SFF, is that it has 5 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the HP ProDesk 400 G5 Mini 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.
The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.
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 G4 SFF is better equipped as it comes with 3 SATA slot(s), while the HP ProDesk 400 G5 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 SFF has 1 M.2 slots while the HP ProDesk 400 G5 Mini 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 ProDesk 400 G5 Mini comes with a decent 150 Watt PSU, but the HP EliteDesk 800 G4 SFF has a more powerful one rated at 250 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.
