Differences between Dell OptiPlex 7000 M and Lenovo ThinkCentre M92 Small

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 7000 M 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 Dell OptiPlex 7000 M is the right one for you. It is smaller than the Lenovo ThinkCentre M92 Small 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 7000 M 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

The Lenovo ThinkCentre M92 Small has 4 RAM slots while the Dell OptiPlex 7000 M 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 Dell OptiPlex 7000 M is using the faster 4800 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 7000 M as it has the ability to run 64 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 7000 M has 9 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 7000 M, is that it has 2 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 7000 M comes with 2 ports, while the Lenovo ThinkCentre M92 Small has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 7000 M 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 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 M92 Small is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 7000 M has 0 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 Dell OptiPlex 7000 M. 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 Dell OptiPlex 7000 M comes with a decent 180 Watt PSU, but the Lenovo ThinkCentre M92 Small has a more powerful one rated at 240 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.
