Differences between Dell OptiPlex 3020 SFF and Lenovo ThinkCentre M92p Small
If you are looking for the smaller form factor the Dell OptiPlex 3020 SFF is the right one for you. It is smaller than the Lenovo ThinkCentre M92p Small and will fit more easily under your desk.
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 3020 SFF as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M92p Small is bad - it can still run some powerful CPUs, albeit being an older generation.
The Lenovo ThinkCentre M92p Small has 4 RAM slots while the Dell OptiPlex 3020 SFF 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 M92p Small as it has the ability to run 32 GB of RAM. The Dell OptiPlex 3020 SFF can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.
Both models have the same amount of USB ports for total count of 8. If this is not enough, using a USB hub is always a viable option. 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 M92p Small is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 3020 SFF has 2 slot(s).
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell OptiPlex 3020 SFF, nor the Lenovo ThinkCentre M92p Small has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.
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!
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 M92p Small comes with a decent 240 Watt PSU, but the Dell OptiPlex 3020 SFF has a more powerful one rated at 255 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.
