Differences between Dell OptiPlex 3010 DT and Dell OptiPlex 9020 MT

If a more modern desktop is what you are looking for, then you should go with the Dell OptiPlex 9020 MT which was released in 2013. 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 9020 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 9020 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 9020 MT has 4 RAM slots while the Dell OptiPlex 3010 DT has only 2 slot(s). Of course this is not something to worry about. Just make sure you take it into consideration when planning how much RAM will your system be using.

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 1600. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 9020 MT as it has the ability to run 32 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 most users.

Ports

In total the Dell OptiPlex 9020 MT has 10 USB ports. The Dell OptiPlex 3010 DT is inferior in this regard and packs 8 USB ports. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals you will need to look at other models.

Unfortunately, only the Dell OptiPlex 9020 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 mode conversion.

The Dell OptiPlex 3010 DT comes with an HDMI port, while the Dell OptiPlex 9020 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 slot is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 4 SATA slots.

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA. Unfortunately, neither the Dell OptiPlex 3010 DT, nor the Dell OptiPlex 9020 MT has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

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 3010 DT comes with a decent 250 Watt PSU, but the Dell OptiPlex 9020 MT has a more powerful one rated at 290 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.
