Dell OptiPlex 9020 MT vs. Fujitsu Esprimo D6011
Comparison and Differences
Differences between Dell OptiPlex 9020 MT and Fujitsu Esprimo D6011
If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo D6011 which was released in 2021. The Dell OptiPlex 9020 MT is older and entered production in 2013.
If you are looking for the smaller form factor the Fujitsu Esprimo D6011 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 Fujitsu Esprimo D6011 as it is running a newer generation CPU. This is not to say that Dell OptiPlex 9020 MT is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
Both models have have equal amount of ram slots (4 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.
The Fujitsu Esprimo D6011 is using the faster 3200 MT/s RAM. The Dell OptiPlex 9020 MT 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 Fujitsu Esprimo D6011 as it has the ability to run 128 GB of RAM. The Dell OptiPlex 9020 MT 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 9020 MT has 10 USB ports. The Fujitsu Esprimo D6011 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. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 9020 MT comes with 2 ports, while the Fujitsu Esprimo D6011 has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 9020 MT is the better choice.
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 9020 MT is better equipped as it comes with 4 SATA slot(s), while the Fujitsu Esprimo D6011 has 3 slot(s).
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 Fujitsu Esprimo D6011. Sadly, the Dell OptiPlex 9020 MT 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 9020 MT comes with a decent 290 Watt PSU, but the Fujitsu Esprimo D6011 has a more powerful one rated at 300 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.
