Differences between Dell OptiPlex 5080M and Dell OptiPlex 7080 MT

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

If you are looking for the smaller form factor the Dell OptiPlex 5080M is the right one for you. It is smaller than the Dell OptiPlex 7080 MT and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 10 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 7080 MT has 4 RAM slots while the Dell OptiPlex 5080M 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.

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. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 7080 MT as it has the ability to run 128 GB of RAM. The Dell OptiPlex 5080M 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 7080 MT has 10 USB ports. The Dell OptiPlex 5080M 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 7080 MT as it has 3 USB3.1 ports (the Dell OptiPlex 5080M has 1).

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 Dell OptiPlex 7080 MT is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 5080M has 1 slot(s).

An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the Dell OptiPlex 7080 MT has 1 M.2 slots while the Dell OptiPlex 5080M comes with just 1.

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 5080M comes with a decent 130 Watt PSU, but the Dell OptiPlex 7080 MT has a more powerful one rated at 500 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.
