Differences between Fujitsu Esprimo Q920 and HP ProDesk 400 G3 SFF

If you are looking for a more modern desktop, then you should go with the HP ProDesk 400 G3 SFF which was released in 2016. The Fujitsu Esprimo Q920 is older and entered production in 2014.

If you are looking for the smaller form factor the Fujitsu Esprimo Q920 is the right one for you. It is smaller than the HP ProDesk 400 G3 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 HP ProDesk 400 G3 SFF as it is running a newer generation CPU. This is not to say that Fujitsu Esprimo Q920 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 HP ProDesk 400 G3 SFF is using the faster 2133 MT/s RAM. The Fujitsu Esprimo Q920 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 HP ProDesk 400 G3 SFF as it has the ability to run 32 GB of RAM. The Fujitsu Esprimo Q920 can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the HP ProDesk 400 G3 SFF has 8 USB ports. The Fujitsu Esprimo Q920 is inferior in this regard and packs 6 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 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.

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the HP ProDesk 400 G3 SFF, nor the Fujitsu Esprimo Q920 has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

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 Q920 comes with a decent 65 Watt PSU, but the HP ProDesk 400 G3 SFF has a more powerful one rated at 180 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.
