Differences between HP ProDesk 400 G4 Mini and Lenovo ThinkCentre M73 Tiny

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 Lenovo ThinkCentre M73 Tiny is older and entered production in 2013.

Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.

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 Lenovo ThinkCentre M73 Tiny 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 400 G4 Mini is using the faster 2400 MT/s RAM. The Lenovo ThinkCentre M73 Tiny is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 400 G4 Mini as it has the ability to run 32 GB of RAM. The Lenovo ThinkCentre M73 Tiny 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 ProDesk 400 G4 Mini has 6 USB ports. The Lenovo ThinkCentre M73 Tiny is inferior in this regard and packs 5 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 ProDesk 400 G4 Mini comes with 2 ports, while the Lenovo ThinkCentre M73 Tiny has only 1. If you are planning to use multiple monitors, the HP ProDesk 400 G4 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 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.

If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the HP ProDesk 400 G4 Mini. Sadly, the Lenovo ThinkCentre M73 Tiny has no such slot, and you will be forced to use the SATA interface instead.

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 Lenovo ThinkCentre M73 Tiny comes with a decent 65 Watt PSU, but the HP ProDesk 400 G4 Mini has a more powerful one rated at 150 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.
