Differences between Dell OptiPlex 5040 MT and Fujitsu Esprimo E720

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 5040 MT which was released in 2015. The Fujitsu Esprimo E720 is older and entered production in 2014.

If you are looking for the smaller form factor the Fujitsu Esprimo E720 is the right one for you. It is smaller than the Dell OptiPlex 5040 MT 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 Dell OptiPlex 5040 MT as it is running a newer generation CPU. This is not to say that Fujitsu Esprimo E720 is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (4 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.

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 1600. Additionally, if you will be needing a lot of RAM, better go for the Fujitsu Esprimo E720 as it has the ability to run 32 GB of RAM. The Dell OptiPlex 5040 MT 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 Fujitsu Esprimo E720 has 12 USB ports. The Dell OptiPlex 5040 MT is inferior in this regard and packs 10 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.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 5040 MT comes with 2 ports, while the Fujitsu Esprimo E720 has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 5040 MT is the better choice.

The Dell OptiPlex 5040 MT comes with an HDMI port, while the Fujitsu Esprimo E720 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 E720 is better equipped as it comes with 5 SATA slot(s), while the Dell OptiPlex 5040 MT has 4 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 Dell OptiPlex 5040 MT. Sadly, the Fujitsu Esprimo E720 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 Dell OptiPlex 5040 MT comes with a decent 240 Watt PSU, but the Fujitsu Esprimo E720 has a more powerful one rated at 280 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.
