Differences between Fujitsu Esprimo D756 and Fujitsu Esprimo P556

If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo D756 which was released in 2016. The Fujitsu Esprimo P556 is older and entered production in 2015.

If you are looking for the smaller form factor the Fujitsu Esprimo D756 is the right one for you. It is smaller than the Fujitsu Esprimo P556 and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 6 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.

Memory

The Fujitsu Esprimo D756 has 4 RAM slots while the Fujitsu Esprimo P556 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.

None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 2133. Additionally, if you will be needing a lot of RAM, better go for the Fujitsu Esprimo D756 as it has the ability to run 64 GB of RAM. The Fujitsu Esprimo P556 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 10. 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.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Fujitsu Esprimo D756 comes with 2 ports, while the Fujitsu Esprimo P556 has only 1. If you are planning to use multiple monitors, the Fujitsu Esprimo D756 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 D756 is better equipped as it comes with 5 SATA slot(s), while the Fujitsu Esprimo P556 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 D756. Sadly, the Fujitsu Esprimo P556 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 280 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.
