Differences between Dell OptiPlex 5070M and Dell OptiPlex 5080 SFF

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 5080 SFF which was released in 2020. The Dell OptiPlex 5070M is older and entered production in 2019.

If you are looking for the smaller form factor the Dell OptiPlex 5070M is the right one for you. It is smaller than the Dell OptiPlex 5080 SFF and will fit more easily under your desk.

Processor

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 5080 SFF as it is running a newer generation CPU. This is not to say that Dell OptiPlex 5070M is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Dell OptiPlex 5080 SFF has 4 RAM slots while the Dell OptiPlex 5070M 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 5080 SFF is using the faster 2933 MT/s RAM. The Dell OptiPlex 5070M is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 5080 SFF as it has the ability to run 128 GB of RAM. The Dell OptiPlex 5070M can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the Dell OptiPlex 5080 SFF has 10 USB ports. The Dell OptiPlex 5070M 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. Both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. This is especially crucial if you are using external drives on a regular basis.

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 5080 SFF is better equipped as it comes with 3 SATA slot(s), while the Dell OptiPlex 5070M has 1 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 5070M comes with a decent 90 Watt PSU, but the Dell OptiPlex 5080 SFF has a more powerful one rated at 200 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.
