Dell OptiPlex 3040 MT vs. Fujitsu Esprimo P7010
Comparison and Differences
Differences between Dell OptiPlex 3040 MT and Fujitsu Esprimo P7010
If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo P7010 which was released in 2020. The Dell OptiPlex 3040 MT is older and entered production in 2015.
Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.
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 P7010 as it is running a newer generation CPU. This is not to say that Dell OptiPlex 3040 MT is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Fujitsu Esprimo P7010 has 4 RAM slots while the Dell OptiPlex 3040 MT 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 P7010 is using the faster 2933 MT/s RAM. The Dell OptiPlex 3040 MT 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 Fujitsu Esprimo P7010 as it has the ability to run 128 GB of RAM. The Dell OptiPlex 3040 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 P7010 has 12 USB ports. The Dell OptiPlex 3040 MT 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 P7010, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 3040 MT 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 P7010 comes with 2 ports, while the Dell OptiPlex 3040 MT has only 1. If you are planning to use multiple monitors, the Fujitsu Esprimo P7010 is the better choice.
The Dell OptiPlex 3040 MT comes with an HDMI port, while the Fujitsu Esprimo P7010 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 P7010 is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 3040 MT 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 P7010. Sadly, the Dell OptiPlex 3040 MT 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 3040 MT comes with a decent 240 Watt PSU, but the Fujitsu Esprimo P7010 has a more powerful one rated at 300 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.
