Differences between HP ProDesk 400 G4 Microtower and Lenovo ThinkCentre M73 Tower
If you are looking for a more modern desktop, then you should go with the HP ProDesk 400 G4 Microtower which was released in 2017. The Lenovo ThinkCentre M73 Tower is older and entered production in 2013.
Form factor wise the models are the same. This means that they are of similar size and form.
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 Microtower as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M73 Tower is bad - it can still run some powerful CPUs, albeit being an older generation.
RAM slots is where your insert your RAM sticks. Each of those two models has 2 RAM slot(s) which should be taken into account when planning how much and what combination of RAM you are going to need.The HP ProDesk 400 G4 Microtower is using the faster 2400 MT/s RAM. The Lenovo ThinkCentre M73 Tower 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 Microtower as it has the ability to run 64 GB of RAM. The Lenovo ThinkCentre M73 Tower can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.
In total the HP ProDesk 400 G4 Microtower has 8 USB ports. The Lenovo ThinkCentre M73 Tower 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 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 3 SATA slot(s). Keep in mind that having too few SATA slots might limmit your options for connecting additional memory drives.
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the HP ProDesk 400 G4 Microtower, nor the Lenovo ThinkCentre M73 Tower has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.Remark: 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!
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 Microtower comes with a decent 310 Watt PSU, but the Lenovo ThinkCentre M73 Tower has a more powerful one rated at 450 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.
