Dell Inspiron 3880 vs. Dell OptiPlex 5000 M
Comparison and Differences
Differences between Dell Inspiron 3880 and Dell OptiPlex 5000 M
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 5000 M which was released in 2022. The Dell Inspiron 3880 is older and entered production in 2020.
If you are looking for the smaller form factor the Dell OptiPlex 5000 M is the right one for you. It is smaller than the Dell Inspiron 3880 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 5000 M as it is running a newer generation CPU. This is not to say that Dell Inspiron 3880 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 OptiPlex 5000 M is using the faster 3200 MT/s RAM. The Dell Inspiron 3880 is slower by supporting RAM speeds of up to 2933 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 64 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 Inspiron 3880 has 8 USB ports. The Dell OptiPlex 5000 M is inferior in this regard and packs 6 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Dell OptiPlex 5000 M, is that it has 1 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell Inspiron 3880 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 OptiPlex 5000 M has a DisplayPort. The Dell Inspiron 3880 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 3880 comes with an HDMI port, while the Dell OptiPlex 5000 M 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 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 3880 is better equipped as it comes with 2 SATA slot(s), while the Dell OptiPlex 5000 M has 0 slot(s).
An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the Dell OptiPlex 5000 M has 1 M.2 slots while the Dell Inspiron 3880 comes with just 1.
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 5000 M comes with a decent 180 Watt PSU, but the Dell Inspiron 3880 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.
