Differences between Lenovo ThinkCentre M73 Small and Lenovo ThinkCentre M83 Small Pro

Both computers, the 2013 and the 2013, were released during the same year - 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 Lenovo ThinkCentre M83 Small Pro has 4 RAM slots while the Lenovo ThinkCentre M73 Small 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 Lenovo ThinkCentre M83 Small Pro as it has the ability to run 32 GB of RAM. The Lenovo ThinkCentre M73 Small can do a bit less at max 16 GB. Most of the times, this should be sufficient for most users.

Ports

In total the Lenovo ThinkCentre M83 Small Pro has 8 USB ports. The Lenovo ThinkCentre M73 Small 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 Lenovo ThinkCentre M83 Small Pro comes with 2 ports, while the Lenovo ThinkCentre M73 Small 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 Lenovo ThinkCentre M83 Small Pro is better equipped as it comes with 4 SATA slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA. Unfortunately, neither the Lenovo ThinkCentre M73 Small, nor the Lenovo ThinkCentre M83 Small Pro 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 Lenovo ThinkCentre M73 Small comes with a decent 240 Watt PSU, but the Lenovo ThinkCentre M83 Small Pro 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.
