Differences between HP ProDesk 490 G2 Microtower and Lenovo ThinkCentre M73 Tower

If a more modern desktop is what you are looking for, then you should go with the HP ProDesk 490 G2 Microtower which was released in 2014. The Lenovo ThinkCentre M73 Tower is older and entered production in 2013.

Form factor wise the models are the same - both desktops are of similar size and form.

Processor

The two models support the same generation of Intel Core processors. We think that the 4 generation of Intel Core has enough power to execute all of the home and office tasks that most people will care to do.

Memory

The HP ProDesk 490 G2 Microtower has 4 RAM slots while the Lenovo ThinkCentre M73 Tower has only 2 slot(s). Of course this is not something to worry about. Just make sure you take it into consideration when planning how much RAM will your system be using.

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 1600. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 490 G2 Microtower as it has the ability to run 32 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 most users.

Ports

In total the HP ProDesk 490 G2 Microtower has 8 USB ports. The Lenovo ThinkCentre M73 Tower 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.

Unfortunately, only the Lenovo ThinkCentre M73 Tower has a DisplayPort. The HP ProDesk 490 G2 Microtower does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of mode conversion.

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

SATA slot is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 3 SATA slots.

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA. Unfortunately, neither the HP ProDesk 490 G2 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 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 490 G2 Microtower comes with a decent 300 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.
