Dell OptiPlex 5000 Tower vs. Lenovo ThinkCentre M92 Small

Differences between Dell OptiPlex 5000 Tower and Lenovo ThinkCentre M92 Small

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 5000 Tower which was released in 2022. The Lenovo ThinkCentre M92 Small is older and entered production in 2011.

If you are looking for the smaller form factor the Lenovo ThinkCentre M92 Small is the right one for you. It is smaller than the Dell OptiPlex 5000 Tower 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 5000 Tower as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M92 Small is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (4 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.

The Dell OptiPlex 5000 Tower is using the faster 3200 MT/s RAM. The Lenovo ThinkCentre M92 Small 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 Dell OptiPlex 5000 Tower as it has the ability to run 128 GB of RAM. The Lenovo ThinkCentre M92 Small can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the Dell OptiPlex 5000 Tower has 10 USB ports. The Lenovo ThinkCentre M92 Small is inferior in this regard and packs 8 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Dell OptiPlex 5000 Tower, is that it has 1 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Lenovo ThinkCentre M92 Small has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 5000 Tower comes with 2 ports, while the Lenovo ThinkCentre M92 Small has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 5000 Tower is the better choice.

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 4 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.

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 5000 Tower. Sadly, the Lenovo ThinkCentre M92 Small 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 M92 Small comes with a decent 240 Watt PSU, but the Dell OptiPlex 5000 Tower has a more powerful one rated at 400 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.
