Differences between Dell Inspiron 3881 and Dell Inspiron 620s

If you are looking for a more modern desktop, then you should go with the Dell Inspiron 3881 which was released in 2020. The Dell Inspiron 620s is older and entered production in 2012.

If you are looking for the smaller form factor the Dell Inspiron 620s is the right one for you. It is smaller than the Dell Inspiron 3881 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 Inspiron 3881 as it is running a newer generation CPU. This is not to say that Dell Inspiron 620s is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (2 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 Dell Inspiron 3881 is using the faster 2933 MT/s RAM. The Dell Inspiron 620s 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 Inspiron 3881 as it has the ability to run 64 GB of RAM. The Dell Inspiron 620s can do a bit less at max 8 GB. Most of the times, this should be sufficient for the majority of users.

Ports

Both models have the same amount of USB ports for total count of 8. If this is not enough, using a USB hub is always a viable option. What is nice about the Dell Inspiron 3881, is that it has 1 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell Inspiron 620s 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 Inspiron 3881 has a DisplayPort. The Dell Inspiron 620s does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

In case your monitor supports HDMI only, you will be happy to hear that both models come with an HDMI port.

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 Inspiron 620s is better equipped as it comes with 4 SATA slot(s), while the Dell Inspiron 3881 has 2 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 Dell Inspiron 3881. Sadly, the Dell Inspiron 620s 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 Inspiron 620s comes with a decent 250 Watt PSU, but the Dell Inspiron 3881 has a more powerful one rated at 260 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.
