Differences between Dell OptiPlex 5040 MT and Lenovo ThinkCentre M93 Small Pro

If a more modern desktop is what you are looking for, then you should go with the Dell OptiPlex 5040 MT which was released in 2015. The Lenovo ThinkCentre M93 Small Pro is older and entered production in 2013.

If you are looking for the smaller form factor the Lenovo ThinkCentre M93 Small Pro is the right one for you. It is smaller than the Dell OptiPlex 5040 MT 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 Dell OptiPlex 5040 MT as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M93 Small Pro is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

RAM slots is where your insert your RAM sticks. Each of those two models has 4 RAM slot(s) which should be taken into account when planning how much and what combination of RAM you are going to need.

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 M93 Small Pro as it has the ability to run 32 GB of RAM. The Dell OptiPlex 5040 MT can do a bit less at max 16 GB. Most of the times, this should be sufficient for most users.

Ports

In total the Dell OptiPlex 5040 MT has 10 USB ports. The Lenovo ThinkCentre M93 Small Pro is inferior in this regard and packs 8 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.

The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. It is good to see that both of the models come with a DisplayPort.

The Dell OptiPlex 5040 MT comes with an HDMI port, while the Lenovo ThinkCentre M93 Small Pro does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).

SATA slot is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 4 SATA slots.

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 Dell OptiPlex 5040 MT. Sadly, the Lenovo ThinkCentre M93 Small Pro has no such slot, and you will be forced to use the SATA interface instead.

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

Looking at the Power Supply Unit (PSU) of the two models we don't see any differences. For either of them you get a maximum power of 240 Watts. Howver be careful, many models have more than one power supply option. When buying your computer, it is a good idea to get a version with the most powerful PSU option.
