Differences between Dell OptiPlex M 7020 2024 and Dell OptiPlex SFF Plus 7020 2024

Both computers, the Dell OptiPlex M 7020 2024 and the Dell OptiPlex SFF Plus 7020 2024, were released during the same year - 2024.

If you are looking for the smaller form factor the Dell OptiPlex M 7020 2024 is the right one for you. It is smaller than the Dell OptiPlex SFF Plus 7020 2024 and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 14 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.

Memory

The Dell OptiPlex SFF Plus 7020 2024 has 4 RAM slots while the Dell OptiPlex M 7020 2024 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 M 7020 2024 is using the faster 5600 MT/s RAM. The Dell OptiPlex SFF Plus 7020 2024 is slower by supporting RAM speeds of up to 4400 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex SFF Plus 7020 2024 as it has the ability to run 128 GB of RAM. The Dell OptiPlex M 7020 2024 can do a bit less at max 64 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the Dell OptiPlex SFF Plus 7020 2024 has 10 USB ports. The Dell OptiPlex M 7020 2024 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. It's great that both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. But if you need maximum connectivity, go with the Dell OptiPlex SFF Plus 7020 2024 as it has 2 USB3.1 ports (the Dell OptiPlex M 7020 2024 has 1).

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex SFF Plus 7020 2024 comes with 3 ports, while the Dell OptiPlex M 7020 2024 has only 1. If you are planning to use multiple monitors, the Dell OptiPlex SFF Plus 7020 2024 is the better choice.

The Dell OptiPlex M 7020 2024 comes with an HDMI port, while the Dell OptiPlex SFF Plus 7020 2024 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 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 Dell OptiPlex SFF Plus 7020 2024 is better equipped as it comes with 3 SATA slot(s), while the Dell OptiPlex M 7020 2024 has 0 slot(s).

When your goal is to have the fastest SSD transfer speeds, an M.2 interface is crucial. Thus, it is good that both models have M.2 SSD slots. Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to invest in SATA drives anymore.

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 M 7020 2024 comes with a decent 90 Watt PSU, but the Dell OptiPlex SFF Plus 7020 2024 has a more powerful one rated at 300 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.
