Dell Vostro 5880 vs. Fujitsu Esprimo E520
Comparison and Differences
Differences between Dell Vostro 5880 and Fujitsu Esprimo E520
If you are looking for a more modern desktop, then you should go with the Dell Vostro 5880 which was released in 2020. The Fujitsu Esprimo E520 is older and entered production in 2014.
If you are looking for the smaller form factor the Fujitsu Esprimo E520 is the right one for you. It is smaller than the Dell Vostro 5880 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 Vostro 5880 as it is running a newer generation CPU. This is not to say that Fujitsu Esprimo E520 is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Fujitsu Esprimo E520 has 4 RAM slots while the Dell Vostro 5880 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.
The Dell Vostro 5880 is using the faster 2933 MT/s RAM. The Fujitsu Esprimo E520 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 Vostro 5880 as it has the ability to run 64 GB of RAM. The Fujitsu Esprimo E520 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 Vostro 5880 has 9 USB ports. The Fujitsu Esprimo E520 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.
The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.
The Dell Vostro 5880 comes with an HDMI port, while the Fujitsu Esprimo E520 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 Vostro 5880. Sadly, the Fujitsu Esprimo E520 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 Fujitsu Esprimo E520 comes with a decent 280 Watt PSU, but the Dell Vostro 5880 has a more powerful one rated at 460 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.
