Dell OptiPlex 790 DT vs. Fujitsu Esprimo D7010 8
Comparison and Differences
Differences between Dell OptiPlex 790 DT and Fujitsu Esprimo D7010 8
If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo D7010 8 which was released in 2020. The Dell OptiPlex 790 DT is older and entered production in 2011.
If you are looking for the smaller form factor the Fujitsu Esprimo D7010 8 is the right one for you. It is smaller than the Dell OptiPlex 790 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 D7010 8 as it is running a newer generation CPU. This is not to say that Dell OptiPlex 790 DT is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Fujitsu Esprimo D7010 8 has 4 RAM slots while the Dell OptiPlex 790 DT 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 D7010 8 is using the faster 2933 MT/s RAM. The Dell OptiPlex 790 DT is slower by supporting RAM speeds of up to 1333 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Fujitsu Esprimo D7010 8 as it has the ability to run 128 GB of RAM. The Dell OptiPlex 790 DT can do a bit less at max 16 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 8. 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 D7010 8 comes with 2 ports, while the Dell OptiPlex 790 DT has only 1. If you are planning to use multiple monitors, the Fujitsu Esprimo D7010 8 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 D7010 8. Sadly, the Dell OptiPlex 790 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 790 DT comes with a decent 250 Watt PSU, but the Fujitsu Esprimo D7010 8 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.
