Differences between HP EliteDesk 800 G1 USDT and HP ProDesk 400 G1 Mini

If you are looking for a more modern desktop, then you should go with the HP ProDesk 400 G1 Mini which was released in 2014. The HP EliteDesk 800 G1 USDT is older and entered production in 2013.

If you are looking for the smaller form factor the HP ProDesk 400 G1 Mini is the right one for you. It is smaller than the HP EliteDesk 800 G1 USDT and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 4 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 G1 USDT has 4 RAM slots while the HP ProDesk 400 G1 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 1600. Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G1 USDT as it has the ability to run 32 GB of RAM. The HP ProDesk 400 G1 Mini can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the HP EliteDesk 800 G1 USDT has 10 USB ports. The HP ProDesk 400 G1 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. 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 HP EliteDesk 800 G1 USDT comes with 2 ports, while the HP ProDesk 400 G1 Mini has only 1. If you are planning to use multiple monitors, the HP EliteDesk 800 G1 USDT 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 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 1 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.

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 ProDesk 400 G1 Mini comes with a decent 65 Watt PSU, but the HP EliteDesk 800 G1 USDT has a more powerful one rated at 180 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.
