Dell OptiPlex 3010 DT vs. Dell OptiPlex 5080 MT
Comparison and Differences
Differences between Dell OptiPlex 3010 DT and Dell OptiPlex 5080 MT
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 5080 MT which was released in 2020. The Dell OptiPlex 3010 DT is older and entered production in 2012.
If you are looking for the smaller form factor the Dell OptiPlex 3010 DT is the right one for you. It is smaller than the Dell OptiPlex 5080 MT 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 MT as it is running a newer generation CPU. This is not to say that Dell OptiPlex 3010 DT is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Dell OptiPlex 5080 MT has 4 RAM slots while the Dell OptiPlex 3010 DT 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 MT is using the faster 2933 MT/s RAM. The Dell OptiPlex 3010 DT is slower by supporting RAM speeds of up to 1600 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 3010 DT can do a bit less at max 8 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Dell OptiPlex 5080 MT has 10 USB ports. The Dell OptiPlex 3010 DT is inferior in this regard and packs 8 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Dell OptiPlex 5080 MT, is that it has 1 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 3010 DT has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.
Unfortunately, only the Dell OptiPlex 5080 MT has a DisplayPort. The Dell OptiPlex 3010 DT does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
The Dell OptiPlex 3010 DT comes with an HDMI port, while the Dell OptiPlex 5080 MT does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).
SATA slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 4 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the Dell OptiPlex 5080 MT. Sadly, the Dell OptiPlex 3010 DT has no such slot, and you will be forced to use the SATA interface instead.
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 3010 DT comes with a decent 250 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, especially if you plan to upgrade to a powerful GPU.
