Dell OptiPlex 7010 DT vs. Fujitsu Esprimo D556
Comparison and Differences
Differences between Dell OptiPlex 7010 DT and Fujitsu Esprimo D556
If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo D556 which was released in 2015. The Dell OptiPlex 7010 DT is older and entered production in 2012.
If you are looking for the smaller form factor the Fujitsu Esprimo D556 is the right one for you. It is smaller than the Dell OptiPlex 7010 DT 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 D556 as it is running a newer generation CPU. This is not to say that Dell OptiPlex 7010 DT is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Dell OptiPlex 7010 DT has 4 RAM slots while the Fujitsu Esprimo D556 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 D556 is using the faster 2133 MT/s RAM. The Dell OptiPlex 7010 DT is slower by supporting RAM speeds of up to 1600 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 32 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.
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 Dell OptiPlex 7010 DT comes with 2 ports, while the Fujitsu Esprimo D556 has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 7010 DT 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 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 3 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
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 D556. Sadly, the Dell OptiPlex 7010 DT 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 7010 DT comes with a decent 250 Watt PSU, but the Fujitsu Esprimo D556 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.
