Differences between HP ProDesk 400 G5 Microtower and HP ProDesk 600 G6 Mini

If you are looking for a more modern desktop, then you should go with the HP ProDesk 600 G6 Mini which was released in 2020. The HP ProDesk 400 G5 Microtower is older and entered production in 2018.

If you are looking for the smaller form factor the HP ProDesk 600 G6 Mini is the right one for you. It is smaller than the HP ProDesk 400 G5 Microtower 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 HP ProDesk 600 G6 Mini as it is running a newer generation CPU. This is not to say that HP ProDesk 400 G5 Microtower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (2 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.

The HP ProDesk 600 G6 Mini is using the faster 3200 MT/s RAM. The HP ProDesk 400 G5 Microtower is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 600 G6 Mini as it has the ability to run 64 GB of RAM. The HP ProDesk 400 G5 Microtower can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the HP ProDesk 400 G5 Microtower has 8 USB ports. The HP ProDesk 600 G6 Mini is inferior in this regard and packs 7 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the HP ProDesk 600 G6 Mini, is that it has 4 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the HP ProDesk 400 G5 Microtower 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.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP ProDesk 600 G6 Mini comes with 2 ports, while the HP ProDesk 400 G5 Microtower has only 1. If you are planning to use multiple monitors, the HP ProDesk 600 G6 Mini 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 ProDesk 400 G5 Microtower is better equipped as it comes with 3 SATA slot(s), while the HP ProDesk 600 G6 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 ProDesk 600 G6 Mini has 1 M.2 slots while the HP ProDesk 400 G5 Microtower 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 600 G6 Mini comes with a decent 95 Watt PSU, but the HP ProDesk 400 G5 Microtower has a more powerful one rated at 310 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.
