Fujitsu Esprimo D9012 vs. HP ProDesk 400 G3 Microtower
Comparison and Differences
Differences between Fujitsu Esprimo D9012 and HP ProDesk 400 G3 Microtower
If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo D9012 which was released in 2022. The HP ProDesk 400 G3 Microtower is older and entered production in 2015.
If you are looking for the smaller form factor the Fujitsu Esprimo D9012 is the right one for you. It is smaller than the HP ProDesk 400 G3 Microtower 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 D9012 as it is running a newer generation CPU. This is not to say that HP ProDesk 400 G3 Microtower is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Fujitsu Esprimo D9012 has 4 RAM slots while the HP ProDesk 400 G3 Microtower 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 D9012 is using the faster 3200 MT/s RAM. The HP ProDesk 400 G3 Microtower 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 Fujitsu Esprimo D9012 as it has the ability to run 128 GB of RAM. The HP ProDesk 400 G3 Microtower 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 D9012 has 12 USB ports. The HP ProDesk 400 G3 Microtower 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. What is nice about the Fujitsu Esprimo D9012, is that it has 5 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the HP ProDesk 400 G3 Microtower has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Fujitsu Esprimo D9012 comes with 2 ports, while the HP ProDesk 400 G3 Microtower has only 1. If you are planning to use multiple monitors, the Fujitsu Esprimo D9012 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 D9012 is better equipped as it comes with 5 SATA slot(s), while the HP ProDesk 400 G3 Microtower has 3 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 D9012. Sadly, the HP ProDesk 400 G3 Microtower 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
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 300 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.
