Differences between Fujitsu Esprimo D538 and Fujitsu Esprimo Q558

Both computers, the Fujitsu Esprimo D538 and the Fujitsu Esprimo Q558, were released during the same year - 2018.

If you are looking for the smaller form factor the Fujitsu Esprimo Q558 is the right one for you. It is smaller than the Fujitsu Esprimo D538 and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 9 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.

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.

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 2666. In addition, you will be able to install the same amount of RAM in both models, and most probably 32 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

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. 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.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Fujitsu Esprimo Q558 comes with 2 ports, while the Fujitsu Esprimo D538 has only 1. If you are planning to use multiple monitors, the Fujitsu Esprimo Q558 is the better choice.

None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.

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 Fujitsu Esprimo D538 is better equipped as it comes with 3 SATA slot(s), while the Fujitsu Esprimo Q558 has 2 slot(s).

When your goal is to have the fastest SSD transfer speeds, an M.2 interface is crucial. Thus, it is good that both models have M.2 SSD slots. Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to invest in SATA drives anymore.

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 Q558 comes with a decent 65 Watt PSU, but the Fujitsu Esprimo D538 has a more powerful one rated at 280 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.
