Dell Vostro 3690 vs. Fujitsu Esprimo Q558
Comparison and Differences
Differences between Dell Vostro 3690 and Fujitsu Esprimo Q558
If you are looking for a more modern desktop, then you should go with the Dell Vostro 3690 which was released in 2021. The Fujitsu Esprimo Q558 is older and entered production in 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 Dell Vostro 3690 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 3690 as it is running a newer generation CPU. This is not to say that Fujitsu Esprimo Q558 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 Vostro 3690 is using the faster 2933 MT/s RAM. The Fujitsu Esprimo Q558 is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell Vostro 3690 as it has the ability to run 64 GB of RAM. The Fujitsu Esprimo Q558 can do a bit less at max 32 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. 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 Fujitsu Esprimo Q558 has a DisplayPort. The Dell Vostro 3690 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 Vostro 3690 comes with an HDMI port, while the Fujitsu Esprimo Q558 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 2 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
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 Dell Vostro 3690 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.
