The HP ProDesk 400 G6 SFF is using the faster 2666 MT/s RAM. The HP ProDesk 400 G4 Mini is slower by supporting RAM speeds of only up to 2400 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 400 G6 SFF 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 most users.

Ports

In total the HP ProDesk 400 G6 SFF has 8 USB ports. The HP ProDesk 400 G4 Mini is inferior in this regard and packs 6 USB ports. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals you will need to look at other models.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP ProDesk 400 G4 Mini comes with 2 ports, while the HP ProDesk 400 G6 SFF has only 1.

None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter.

SATA port 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 G6 SFF is better equipped as it comes with 2 SATA 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 buy SATA drives anymore.

Remark: Make sure that the M.2 slot supports the PCIe (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 6 Gb/s, while the PCIe 3.0 x4 will support speeds up to 32 Gb/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 400 G6 SFF 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.
