Differences between Lenovo ThinkCentre M83 Small Pro and Lenovo ThinkCentre M900 Tiny

If you are looking for a more modern desktop, then you should go with the Lenovo ThinkCentre M900 Tiny which was released in 2015. The Lenovo ThinkCentre M83 Small Pro is older and entered production in 2013.

If you are looking for the smaller form factor the Lenovo ThinkCentre M900 Tiny is the right one for you. It is smaller than the Lenovo ThinkCentre M83 Small Pro and will fit more easily under your desk.

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 Lenovo ThinkCentre M900 Tiny as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M83 Small Pro is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Lenovo ThinkCentre M83 Small Pro has 4 RAM slots while the Lenovo ThinkCentre M900 Tiny has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.

The Lenovo ThinkCentre M900 Tiny is using the faster 2133 MT/s RAM. The Lenovo ThinkCentre M83 Small Pro is slower by supporting RAM speeds of up to 1600 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 32 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.

Ports

In total the Lenovo ThinkCentre M83 Small Pro has 8 USB ports. The Lenovo ThinkCentre M900 Tiny 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 ports are placed on the system board and it 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), while the Lenovo ThinkCentre M900 Tiny has 1 slot(s).

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 Lenovo ThinkCentre M900 Tiny. Sadly, the Lenovo ThinkCentre M83 Small Pro 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 M900 Tiny comes with a decent 65 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, especially if you plan to upgrade to a powerful GPU.
