Differences between Dell OptiPlex 7020 SFF and HP ProDesk 400 G2 SFF
Both computers, the 2014 and the 2014, were released during the same year - 2014.
If you are looking for the smaller form factor the Dell OptiPlex 7020 SFF is the right one for you. It is smaller than the HP ProDesk 400 G2 SFF and will fit more easily under your desk.
Processor
The two models support the same generation of Intel Core processors. We think that the 4 generation of Intel Core has enough power to execute all of the home and office tasks that most people will care to do.
Memory
The Dell OptiPlex 7020 SFF has 4 RAM slots while the HP ProDesk 400 G2 SFF 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. In addition, you will be able to install the same amount of RAM in both models, and most probably 16 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.Ports
In total the Dell OptiPlex 7020 SFF has 10 USB ports. The HP ProDesk 400 G2 SFF 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.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 7020 SFF comes with 2 ports, while the HP ProDesk 400 G2 SFF has only 1.
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 3 SATA slots.
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA. Unfortunately, neither the Dell OptiPlex 7020 SFF, nor the HP ProDesk 400 G2 SFF 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 HP ProDesk 400 G2 SFF comes with a decent 240 Watt PSU, but the Dell OptiPlex 7020 SFF has a more powerful one rated at 255 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.
