Differences between HP ProDesk 400 G4 Mini and HP ProDesk 600 G3 Microtower

If you are looking for a more modern desktop, then you should go with the HP ProDesk 400 G4 Mini which was released in 2018. The HP ProDesk 600 G3 Microtower is older and entered production in 2017.

If you are looking for the smaller form factor the HP ProDesk 400 G4 Mini is the right one for you. It is smaller than the HP ProDesk 600 G3 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 400 G4 Mini as it is running a newer generation CPU. This is not to say that HP ProDesk 600 G3 Microtower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The HP ProDesk 600 G3 Microtower has 4 RAM slots while the HP ProDesk 400 G4 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 2400. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 600 G3 Microtower as it has the ability to run 64 GB of RAM. The HP ProDesk 400 G4 Mini 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 600 G3 Microtower has 11 USB ports. The HP ProDesk 400 G4 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.

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 ProDesk 600 G3 Microtower is better equipped as it comes with 5 SATA slot(s), while the HP ProDesk 400 G4 Mini has 1 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 ProDesk 400 G4 Mini comes with a decent 150 Watt PSU, but the HP ProDesk 600 G3 Microtower 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.
