Differences between Dell Inspiron 3847 and Dell OptiPlex 9020 MT

Both computers, the Dell OptiPlex 9020 MT and the Dell Inspiron 3847, were released during the same year - 2013.

Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.

Processor

The two models have the same generation of Intel processors. We think that the 4 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.

Memory

The Dell OptiPlex 9020 MT has 4 RAM slots while the Dell Inspiron 3847 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.

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 Inspiron 3847 can do a bit less at max 16 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 Dell Inspiron 3847 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.

Unfortunately, only the Dell OptiPlex 9020 MT has a DisplayPort. The Dell Inspiron 3847 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 Inspiron 3847 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 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 Inspiron 3847. 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 Dell Inspiron 3847 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.
