The difference between Dell OptiPlex 5070 MT and Dell OptiPlex 5070 SFF

This page will compare the Dell OptiPlex 5070 MT and Dell OptiPlex 5070 SFF desktop computers. If you are wondering what is the difference between the Dell OptiPlex 5070 MT and Dell OptiPlex 5070 SFF, you are at the right place. We've prepared also a comparison table where you can check the differences in more detail.

Both computers, the Dell OptiPlex 5070 MT and the Dell OptiPlex 5070 SFF, were released during the same year - 2019.

For some use cases size is important. If you are looking for the smaller form factor the Dell OptiPlex 5070 SFF is the right one for you. It is smaller than the Dell OptiPlex 5070 MT and will fit easier under your desk.

The processor

The two models support the same generation of Intel Core processors. We think that the 9th generation Intel Core has enough power to execute all of the home and office tasks that most people will care to do.


RAM slots is where your insert your RAM sticks. Each of those two models have 4 RAM slots which should be taken into account when planning how much and what combination of RAM it\'s going to be used. 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 2666. You will be able to install the same amount of RAM in both models, and most probably 64 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.


Both of the models have a USB 3.1 port which will allow you to exchange data with your peripherals at up to 10 Gb/s.

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.

None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter.

SATA slot is where SSD, HDD and Optical Disk Drives are connected. More SATA slots will allow you to have more Disk Drives running at the same time. In this regard the Dell OptiPlex 5070 MT is better equipped as it comes with 4 SATA slots, while the Dell OptiPlex 5070 SFF has only 3 slots.

When your goal is to have the fastest transfer speeds for your SSD, M.2 interface is crucial. Thus, it is good that both models have an M.2 SSD slot(s). Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to buy SATA drives anymore.
Remark: If you want the fastest M.2 SSD interface, make sure that the slot supports the PCIe interface. Compared to the SATA III, the PCIe 3.0 x4 is more than 5 times faster (6Gb/s vs. 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 5070 SFF comes with a decent 200 Watt PSU, but the Dell OptiPlex 5070 MT has a more powerful one rated at 260 Watts. Choosing either one depends on your specific requirements and use case.
