The difference between Dell OptiPlex 5080 SFF and Dell OptiPlex 7080 SFF

Welcome to our page comparing the Dell OptiPlex 5080 SFF vs. the Dell OptiPlex 7080 SFF. Are you trying to choose between the two desktop computers unsure which one is more suitable for you? This page will try to highlight the differences between the two models: the Dell OptiPlex 5080 SFF vs. Dell OptiPlex 7080 SFF. Don't forget to also check the comparison table where you will find detailed specification.

Both computers, the Dell OptiPlex 5080 SFF and the Dell OptiPlex 7080 SFF, were released during the same year - 2020.

Form wise there is no difference. Both desktops are of similar size and form. We like this Small form factor as it is equally good for office and home setups.

The processor

The two models support the same generation of Intel Core processors. We think that the 10th 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 2933. You will be able to install the same amount of RAM in both models, and most probably 128 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.


What is nice about the Dell OptiPlex 7080 SFF, is that it has USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 5080 SFF has no such port, thus restricting your transfer speeds a bit.

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 you connect SSD, HDD and Optical Disk Drives. Each of the two models being compared have 3 SATA slots. For most use cases this should be enough but you should decide for yourself.

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

Inspecting the Power Supply Unit (PSU) of the two models we don't see any changes. For either of them you get 200 Watts. If you intend to use components or peripherals which require more power, you should either change the PSU, or if this is not possible, just pick another model with more power.
