Fujitsu Esprimo Q958 vs. HP ProDesk 400 G6 Mini
Comparison and Differences
Differences between Fujitsu Esprimo Q958 and HP ProDesk 400 G6 Mini
If you are looking for a more modern desktop, then you should go with the HP ProDesk 400 G6 Mini which was released in 2020. The Fujitsu Esprimo Q958 is older and entered production in 2018.
Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.
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 HP ProDesk 400 G6 Mini as it is running a newer generation CPU. This is not to say that Fujitsu Esprimo Q958 is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Fujitsu Esprimo Q958 has 4 RAM slots while the HP ProDesk 400 G6 Mini 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 HP ProDesk 400 G6 Mini is using the faster 3200 MT/s RAM. The Fujitsu Esprimo Q958 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 HP ProDesk 400 G6 Mini as it has the ability to run 64 GB of RAM. The Fujitsu Esprimo Q958 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 Fujitsu Esprimo Q958 has 9 USB ports. The HP ProDesk 400 G6 Mini is inferior in this regard and packs 7 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. It's great that both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. But if you need maximum connectivity, go with the Fujitsu Esprimo Q958 as it has 5 USB3.1 ports (the HP ProDesk 400 G6 Mini has 2).
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Fujitsu Esprimo Q958 comes with 2 ports, while the HP ProDesk 400 G6 Mini has only 1. If you are planning to use multiple monitors, the Fujitsu Esprimo Q958 is the better choice.
The HP ProDesk 400 G6 Mini comes with an HDMI port, while the Fujitsu Esprimo Q958 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 Fujitsu Esprimo Q958 is better equipped as it comes with 2 SATA slot(s), while the HP ProDesk 400 G6 Mini has 1 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
Looking at the Power Supply Unit (PSU) of the two models we don't see any differences. For either of them you get a maximum power of 65 Watts. However be careful, many models have more than one power supply option. When buying your computer, it is a good idea to get a version with the most powerful PSU. This will potentially allow you to upgrade to a more powerful GPU for example.
