Differences between Dell OptiPlex 5070 MT and Dell OptiPlex 5080 MT

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

Form factor wise the models are the same - both desktops are of similar size and form.

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

Memory

RAM slots is where your insert your RAM sticks. Each of those two models has 4 RAM slot(s) which should be taken into account when planning how much and what combination of RAM you are going to need.

The Dell OptiPlex 5080 MT is using the faster 2933 MT/s RAM. The Dell OptiPlex 5070 MT is slower by supporting RAM speeds of only up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 5080 MT as it has the ability to run 128 GB of RAM. The Dell OptiPlex 5070 MT can do a bit less at max 64 GB. Most of the times, this should be sufficient for most users.

Ports

Total count of USB ports for both computers is 10. Both of the models have USB 3.1 ports 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. Each of the two models being compared have 4 SATA slots.

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 buy SATA drives anymore.

Remark: Make sure that the M.2 slot supports the PCIe (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 6 Gb/s, while the PCIe 3.0 x4 will support speeds up to 32 Gb/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 MT comes with a decent 260 Watt PSU, but the Dell OptiPlex 5080 MT has a more powerful one rated at 360 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.
