Fujitsu Esprimo Q558 vs. HP ProDesk 600 G2 SFF
Comparison and Differences
Differences between Fujitsu Esprimo Q558 and HP ProDesk 600 G2 SFF
If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo Q558 which was released in 2018. The HP ProDesk 600 G2 SFF is older and entered production in 2015.
If you are looking for the smaller form factor the Fujitsu Esprimo Q558 is the right one for you. It is smaller than the HP ProDesk 600 G2 SFF 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 Fujitsu Esprimo Q558 as it is running a newer generation CPU. This is not to say that HP ProDesk 600 G2 SFF is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The HP ProDesk 600 G2 SFF has 4 RAM slots while the Fujitsu Esprimo Q558 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 Fujitsu Esprimo Q558 is using the faster 2666 MT/s RAM. The HP ProDesk 600 G2 SFF is slower by supporting RAM speeds of up to 2133 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 600 G2 SFF 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
In total the HP ProDesk 600 G2 SFF has 10 USB ports. The Fujitsu Esprimo Q558 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.
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 HP ProDesk 600 G2 SFF is better equipped as it comes with 3 SATA slot(s), while the Fujitsu Esprimo Q558 has 2 slot(s).
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 Fujitsu Esprimo Q558. Sadly, the HP ProDesk 600 G2 SFF 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 Q558 comes with a decent 65 Watt PSU, but the HP ProDesk 600 G2 SFF has a more powerful one rated at 200 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.
